1、�ؓ什么是ArcGIS server REST

下面的两�q�图分别描述了ArcIMS 和ArcGIS server REST的是��h��机制

ArcIMS

ArcGIS server REST

从图中的我们可以清晰地看出，如果把黄色虚�U�内看成是黑��q��话，其两�U�服务采用完全一��L��l�构�Q�Webservice) �?不同之处在于ArcIMS 应用发送的是ArcXML 接收的是 ArcXML ,而ArcGIS server REST 应用发送的是GET (POST)��h�� 接收的是 JSON。在之前我们��p��q?ArcIMS之所以广受用��L��好评�Q�就是因为其架构优秀�Q�逻辑清晰�Q�开发方便，而ArcGIS server REST 也秉承了�q�个优点�Q�其架构也是�q�种发送请�?接受�l�果的模式，不但�l�构清晰也利于开发者的开发调试。通过对其发送接受请求的分析能��我们更清楚地认识�q�点�?/p>

应用向ArcIMS的发送请�?nbsp; �Q�getFeatures)

上面一个就是在ArcIMS里发送的查询��h��Q�请求是在cities囑ֱ�中查询名�U�是San diego的地图要素。而下面的Axl��是ArcIMS接受到请求返回的查询�l�果�?/p>

从中我们可以看出San Diego地图要素的一些信�?/p>

下面�q�个��h��是应用向ArcGIS server REST的发送请�?�Q�getFeatures)

不同于向ArcIMS发送的ArcXML 的POST方式�Q�这个请求是通过GET方式发送的字符�Ԍ��从字�W�串的参��C��我们可以看出�Q�其是向地图服务为USA的第0囑ֱ� �Q�cities囑ֱ��Q�发送一个请求，查询�?city_NAME=San Diego 的地图要�?br /> 下面是ArcGIS server REST接受到请求后�q�回的查询结果�?/p>

从上面可以看出，ArcGIS server REST 和ArcIMS 是如此的�怼��Q�都是请求应�{�模式，而相对于ArcIMS �?AXL而言ArcGIS server REST的JSON更适于脚本语言的解析（xml在不同浏览器下解析方法有很大区别�Q�，而且相同内容JSON比AXL更小�Q�这个在大数据结果返回中是很重要的，不仅仅如�?ArcGIS server REST对于ArcIMS开发�h�?而言�q�具有不需要额外学习AO知识 �Q�入门迅速，�{�诸多方面优�ѝ�?/p>

��Z��么是 JavaScript �Q?/p>

在ArcIMS中��用最多的��是JavaScript开发（其次是java connector~�Q�，在很多项目中都是JavaScript做GIS 应用�Q�DotNet或java�Q�J2EE�Q?作业务逻辑�Q�我�怿�大多数ArcIMS开发�h员对JavaScript开发�ƈ不陌生�?/p>

JavaScript 的WebGIS 开发大致分��Z��下的三类�Q?/p>

1、地囄��展示�Q?DIV �?IMG的抽�?/p>

2、信息的查询发送AJAX��h��

3、动态信息的地图展示
对于marker pop ��是DIV
对于Graphic ��是 VML/SVG

下面�q�个是利用JavaScript向ArcIMS ��h��地图的全�q�程�Q�其�?url为ArcIMS服务器servlet connector的地址�Q�axl 为发送的getmap ��h��?/p>

其步骤：
       1、客��L��JavaScript建立xmlhttprequest 通道�Q�向ArcIMS的servlet connector 发送axl��h��Q�黑色JavaScript代码�Q?br />        2、ArcIMS 接受到请求生成图�?br />        3、通过刚才客户端发起徏立的xmlhttprequest 通道�Q�ArcIMS发送AXL�l�客��L��Q�告知生成的地图囄��的url
       4、客��L��JavaScript解析收到的AXL�Q��ƈ告知��面html抽换DIV中的囄��指向url�Q��色代码）
       5、页面通过新的url地址取到ArcIMS刚才生成的地囑֛�片，展示�l�客戗��?/p>

相对于ArcIMS而言 ArcGIS server REST地图��h��更�ؓ��单，如下�?/p>

其步骤：
         1、利用JavaScript拼接��h��的url�Ԍ��传给html
         2、页面请求url
         3、ArcGIS server REST 接受�q�个URL 生成地图囄��以流的方式传�l�页�?br />          4、页面展�C�地囑֛�片给用户
�?br />       以上的Javascript代码没有用到��M��API�Q�其主要目的��是向大家说明，在有强大的服务端支持�Q�ArcIMS/ArcGIS server REST�Q�下利用JavaScript开发WebGIS 应用是一件多么惬意的事情。而且不要忘了,我们�q�有��装大量要素的Javascript API !

1.在页面端�Q�首先撰写自定义的javascript�Ҏ(gu��)��Q�有了这个方法，��可以在前端��面的�Q何地方去触发地图事�g了：

function test(str){

    //需要传递到后台的自定义参数

    var str1=encodeURI(encodeURI(str));

    //“mapForm”是地��N��面上的表单名�Q�从该表单获取向后台提交的URL

    var url = EsriUtils.getServerUrl("mapForm");

    //“map1”是地��N��面上的地图ID

    var map = EsriControls.maps["map1"];

      //定义需要传递的参数列表�Q�最后的“EsriUtils.buildRequestParams(map.formId)”为固定写�?br />
    var params = "addpointInt=addpointInt";//�q�个参数用来在后台判断当前应该做什么操作，从而决定调用哪个处理类�Q�参数名和值都是自定义�?br />
    params += " &mapId=map1 ";//地图的ID

    params += " &str="+str1;//自定义的参数

    params += " &"+EsriUtils.buildRequestParams(map.formId);//固定写法

    //调用sendAjaxRequest�Ҏ(gu��)��Q�发送请求，其中的function(){testCallBack(xmlHttp);}为回调方�?br />
    var xmlHttp = EsriUtils.sendAjaxRequest(url,params,true,function(){testCallBack(xmlHttp);});

}

2.然后是相关的回调�Ҏ(gu��)��Q�回调方法就可以�Ҏ(gu��)��自己的需要随意进行操作了�Q�这只是非常普通的AJAX回调�Ҏ(gu��)��

function testCallBack(xmlHttp){

    if (xmlHttp != null && xmlHttp.readyState == 4 && xmlHttp.status == 200) {

        var xml = xmlHttp.responseXML;

        var map = EsriControls.maps["map1"];

        // map.refresh();

        // alert("run here");

        map.resize(map.bounds.width, map.bounds.height);

    }

}

3.然后是撰写后台程序，用以捕捉前台所触发的AJAX事�g。这是一个listener�Q�需要实现接口javax.faces.event.PhaseListener�Q?br />

import java.util.Map;

import javax.faces.context.ExternalContext;

import javax.faces.context.FacesContext;

import javax.faces.event.PhaseEvent;

import javax.faces.event.PhaseId;

import javax.faces.event.PhaseListener;

public class SelfPhaseListener implements PhaseListener {

        //////////////////////////////ajax处理代码

    public PhaseId getPhaseId() {

        // TODO Auto-generated method stub

        //�q�里表示在应用请求值阶�D�进行处�?br />
        return PhaseId.APPLY_REQUEST_VALUES;//.APPLY_REQUEST_VALUES;//选择action的回调处理过�E?br />
    }





    public void afterPhase(PhaseEvent phaseEvent) {

        //从FacesContext中获得由前端javascript�Ҏ(gu��)��传递来的参数列�?br />
        FacesContext facesContext = phaseEvent.getFacesContext();

        ExternalContext externalContext = facesContext.getExternalContext();

        Map paramMap = externalContext.getRequestParameterMap();



        //�q�里判断是不是我们需要的��h��,如果不是直接�q�回。这�?#8220;addpointInt”��x��先前所定义的javasctipt�Ҏ(gu��)��中的一个参�?br />
        if("addpointInt".equals((String) paramMap.get("addpointInt"))){

                    //�q�个AddPointPhaseListener�c�d��是自定义的用来进行后台处理的�c?br />
            AddPointPhaseListener addpoint=new AddPointPhaseListener();

            addpoint.excute(paramMap, facesContext);

        }

     }

    @Override

    public void beforePhase(PhaseEvent arg0) {

       // TODO Auto-generated method stub



    }

}

4.接下来写一个用来处理具体业务的�c�：

import java.util.Map;

import javax.faces.component.UIComponent;

import javax.faces.context.FacesContext;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import com.esri.adf.web.data.TocFunctionality;

import com.esri.adf.web.data.WebContext;

import com.esri.adf.web.data.WebMap;

import com.esri.adf.web.faces.component.MapControl;

import com.esri.adf.web.faces.renderkit.xml.ajax.AJAXUtil;

import com.esri.adf.web.util.XMLUtil;

public class AddPointPhaseListener {

    @SuppressWarnings("deprecation")

    public void excute(Map paramMap,FacesContext facesContext) {

        try {

            //get form element from view。获得页面上的表单对�?br />
            UIComponent form = facesContext.getViewRoot().findComponent((String) paramMap.get("mapForm"));

            if(form == null){

                return;

            }

            //get map control。获得mapControl

            MapControl mc = (MapControl) form.findComponent((String) paramMap.get("mapId"));

            if(mc == null){

                return;

            }

            //get web map, web context & clear graphics。获得WebMap,WebContext�Q�就可以�q�行地图操作�?br />
            WebMap wm = mc.getWebMap();

            WebContext wc = wm.getWebContext();

            wc.getWebQuery().clearGraphics();



            // read information form string of js function

            //获得从页面javasctipt�Ҏ(gu��)��传递来的参数列�?br />
            String str=java.net.URLDecoder.decode((String) paramMap.get("str"), "UTF-8");

            ///////////////////////

            //如果需要返回的话，像这��L��XML的�Ş式返回数�?br />
            //create and populate xml response document

            Document doc = XMLUtil.newDocument();

            Element responseTag = XMLUtil.createElement(doc, "response", null, null);

            responseTag.setAttribute("test", "hello");

            //write response

            AJAXUtil.writeResponse(facesContext, doc);



        }

        catch (Exception e) {

        }

        finally {

            facesContext.responseComplete();

        }

    }

}

5.最后，需要在faces-context.xml文�g中通过注册生命周期的方式，来��以上�q�些代码生效�Q?br />

地理(投媄)坐标与屏�q�坐标的转换!

��剑��秋 — Wed, 29 Apr 2009 16:41:00 GMT

     刚接触到�q�个东东,��实头晕!什么地理坐�?投媄坐标,屏幕坐标�{�等.......�?...地理知识中学学过(都不知道咋学�?,数学貌似N多年不用也都�q�给老师�?��实�(zh��n)�哀.....�?...�l�于认真的研�I�了一下才��明白是怎么回事�?其实不要��什么地理坐�?投媄坐标�q�是屏幕坐标,搞的你是非要知道天文地理似的才能��d��手去做这个东�?原理掌握一�?那就是只用弄明白地理坐标和屏�q�坐标的定义规则��O(ji��n)K�?..
    地理坐标定义规则:X�?代表�l�度)向右递增,Y�?�U�度)向上递增,��好比小学学�q�的�q�面坐标(貌似又忘�?要重��d��学了)�?向左,向下的规�?�q�个不用我再阐述了吧,如果你还不明�?那我劝你�q�是真要去重��d��学了....比我更�?zh��n)�哀,嘿嘿,�ȝ��扑ֈ�一个知已啊....不容易啊...
    屏幕坐标定义规则:X轴向右递增,Y轴向下递增..
    可以看出,地理坐标和屏�q�坐标的区别仅仅只是在于Y轴递增方向是相反的...(�q�就是不�?.
    好了,现在我们开始�{换他们吧. �q�里��一点的��是��Z��保证�_�ֺ�,地理坐标的度*3600换算成秒,所有的取值用double来计��?最后的�l�果再�{换成int
    1.已知道屏�q�的�?y)和宽(h),地理坐标区域的范�?maxLon,minLon,maxLat,minLat)..�q�里我们知道了这些已知的参数...
    2.我们可以��出每像素所代表的经度和�U�度(有�h�U�这个�ؓ比例因子):
        公式:scaleX = h/((maxLon-minLon)*3600) ----------X轴上每像素代表的�l�度�U�数;
        公式:scaleY = y/((maxLat-minLat)*3600)  -----------Y轴上每像素代表的�U�度�U�数;
        �q�两个比例因子就是两个坐标系之间的关�p?.
    3.很简单的一步了,那就是算��地理坐标区域中的��M��一�?lon,lat)在屏�q�上的坐标了,怎么��?下面来讲:
       公式:screenX = lon*3600/scaleX; ---------屏幕坐标X轴坐�?br />        公式:screenY = lat*3600/scaleY; ----------屏幕坐标Y轴坐�?        怎么�?很简单吧?�q�里我们��q��出地理坐标上��M��一点�{到屏�q�上的坐标是多少�?.....
        �q�有最后一�?那就是我们要把该地理区域占满占个屏幕该怎么办呢?
   4. 接着我们需要该地理区域占满占个屏幕该怎么办呢
        公式:minX = minLon*3600/scaleX;    区域左边�|�最左端
        公式:minY = minLat*3600/scaleY;     区域上面�|�最上端
   5. 当地地理范围区域占满整个屏幕�?我们需要用到第三步计算出来�?nbsp;screenX和screenY两个参数
,该区域中的�Q何一点的公式如下:
       公式:X = screenX - minX = (lon - minLon)*3600/scaleX;
       �׃��U�度的方向和屏幕Y轴是相反�?
       公式:screenMaxLat = (maxLat - minLat)*3600/scaleY;
       公式:screenLat = (lat - minLat)*3600/scaleY;
       公式:Y = screenMaxLat - screenLat = (maxLat - lat)*3600/scaleY;     至于��Z��么是�q�个公式,我想大家仔细��x��明白了..
6.�ȝ��:
        �l�纬度�{屏幕坐标的最�l�公式如�?
        公式: X = (lon - minLon)*3600/scaleX;
        公式: Y =  (maxLat - lat)*3600/scaleY;
  接着我们�׃��面的公式可以推出屏幕坐标转经�U�度坐标公式如下�Q?br /> 　　公式�Q�lon = X * scaleX/3600 + minLon;
        公式�Q�lat = maxLat - y* scaleY/3600;

呼呼......�l�于写完�?�׃��要赶着睡觉,因�ؓ明天�q�要早�v上班,可能写的�q�不够清�?大家再仔�l�研�I�一下就能够明白�?

地理坐标�p�d��大地坐标�p?转蝲)

��剑��秋 — Fri, 26 Dec 2008 06:33:00 GMT

地理坐标�Q��ؓ球面坐标�?参考��^面地�?椭球面。坐标单�?�l�纬�?/p>

大地坐标�Q��ؓ�q�面坐标。参考��^面地�?水��^�?nbsp; 坐标单位�Q�米、千�c�等�?br />

地理坐标转换到大地坐标的�q�程可理解�ؓ投媄�?nbsp; �Q�投影：��不规则的地球曲面�{换�ؓ�q�面�Q?/p>

在ArcGIS中预定义了两套坐标系�Q�地理坐标系�Q�Geographic coordinate system�Q�投影坐标系�Q�Projected coordinate system�Q�，

1、首先理解地理坐标系�Q�Geographic coordinate system�Q�，Geographic coordinate system直译�?
地理坐标�pȝ��Q�是以经�U�度为地囄��存储单位的。很明显�Q�Geographic coordinate syst
em是球面坐标系�l�。我们要��地球上的数字化信息存放到球面坐标系�l�上�Q�如何进行操�?
呢？地球是一个不规则的椭球，如何��数据信息以�U�学的方法存攑ֈ�椭球上？�q�必然要�?
我们扑ֈ��q�样的一个椭球体。这��L��椭球体具有特点：可以量化计算的。具有长半��u�Q�短
半��u�Q�偏心率。以下几行便是Krasovsky_1940椭球及其相应参数�?
Spheroid: Krasovsky_1940
Semimajor Axis: 6378245.000000000000000000

Inverse Flattening�Q�扁率）: 298.300000000000010000
然而有了这个椭球体以后�q�不够，�q�需要一个大地基准面��这个椭球定位。在坐标�pȝ��?
�q�C��Q�可以看到有�q�么一行：
Datum: D_Beijing_1954
表示�Q�大地基准面是D_Beijing_1954�?
--------------------------------------------------------------------------------
有了Spheroid和Datum两个基本条�g�Q�地理坐标系�l�便可以使用�?

Inverse Flattening: 298.300000000000010000

2、接下来便是Projection coordinate system�Q�投影坐标系�l�）�Q�首先看看投影坐
标系�l�中的一些参数�?
Projection: Gauss_Kruger

Central_Meridian: 117.000000
Scale_Factor: 1.000000
Latitude_Of_Origin: 0.000000
Linear Unit: Meter (1.000000)
Geographic Coordinate System:
Name: GCS_Beijing_1954
Alias:
Abbreviation:
Remarks:
Angular Unit: Degree (0.017453292519943299)
Prime Meridian: Greenwich (0.000000000000000000)
Datum: D_Beijing_1954
Spheroid: Krasovsky_1940
Semimajor Axis: 6378245.000000000000000000
Semiminor Axis: 6356863.018773047300000000
Inverse Flattening: 298.300000000000010000
从参��C��可以看出�Q�每一个投影坐标系�l�都必定会有Geographic Coordinate System�?
投媄坐标�pȝ��Q�实质上便是�q�面坐标�pȝ��Q�其地图单位通常为米�?
那么��Z��么投影坐标系�l�中要存在坐标系�l�的参数呢？
�q�时候，又要说明一下投��q��意义�Q�将球面坐标转化为��^面坐标的�q�程便称为投影�?
好了�Q�投��q��条�g��出来了�Q?
a、球面坐�?
b、�{化过�E�（也就是算法）
也就是说�Q�要得到投媄坐标��必��d��有一�?#8220;拿来”投媄的球面坐标，然后才能使用��法
��L��影！
��x��一个投影坐标系�l�都必须要求有Geographic Coordinate System参数�?br />

在Coordinate Systems\Projected Coordinate Systems\Gauss Kruger\Beijing 1954目录中，我们可以看到四种不同的命名方式：

    Beijing 1954 3 Degree GK CM 75E.prj
    Beijing 1954 3 Degree GK Zone 25.prj
    Beijing 1954 GK Zone 13.prj
    Beijing 1954 GK Zone 13N.prj

对它们的说明分别如下�Q?/div>

    三度分带法的北京54坐标�p�，中央�l�线在东75度的分带坐标�Q�横坐标前不加带�?br />     三度分带法的北京54坐标�p�，中央�l�线在东75度的分带坐标�Q�横坐标前加带号

    六度分带法的北京54坐标�p�，分带号�ؓ13�Q�横坐标前不加带�?/div>

在Coordinate Systems\Projected Coordinate Systems\Gauss Kruger\Xian 1980目录中，文�g命名方式又有所变化�Q?/div>

    Xian 1980 3 Degree GK CM 75E.prj
    Xian 1980 3 Degree GK Zone 25.prj
    Xian 1980 GK CM 75E.prj
    Xian 1980 GK Zone 13.prj

西安80坐标文�g的命名方式、含义和北京54前两个坐标相同，但没有出�?#8220;带号+N”�q�种形式�Q��ؓ什么没有采用统一的命名方式？让�h看了有些费解�?/div>

转蝲:数据�~�辑问题

��剑��秋 — Thu, 18 Dec 2008 04:41:00 GMT

              IFeatureClass fc = l.FeatureClass ;

}

上边的代码能��d��点地物，但不能作为最�l�的代码使用�Q�细心的��Z��看到。这�D�代码只是把�W�一层加�q�来�Q�然后在�W�一层上�Ҏ(gu��)��加点地物�Q�如果第一层不是点层，该怎么办，那就要判断了。怎么判断我们以后再说。通过上边的代码，我们已经清楚��C��解到�Q�编辑地物的基本框架�Q�这也是我们所说的事务�Q�如果想操作能返回和重做�Q�就必须把代码写�?font style="line-height: 1.3em" face="Times" size="3">IWorkspaceEdit�?font style="line-height: 1.3em" face="Times" size="3">StartEditing()�?font style="line-height: 1.3em" face="Times" size="3">StopEditing()函数之间�Q�把相关的操作写�?font style="line-height: 1.3em" face="Times" size="3">IWorkspaceEdit�?font style="line-height: 1.3em" face="Times" size="3">StartEditOperation()�?font style="line-height: 1.3em" face="Times" size="3">StopEditOperation()之间。�ƈ且操作是利用IWorkspaceEdit接口完成的，所以要仔细理会IWorkspaceEdit接口的用处，如何工作�I�间都可以�{化�ؓIWorkspaceEdit的对象，当�{化�ؓIWorkspaceEdit定义的对象后�Q�我们定义一�?font style="line-height: 1.3em" face="Times" size="3">IFeature的对象，然后利用IFeatureClass�?font style="line-height: 1.3em" face="Times" size="3">CreateFeature()函数创徏一个地物，�q�赋值给定义�?font style="line-height: 1.3em" face="Times" size="3">IFeature对象。接着讄��IFeature对象的一些属性，如：坐标��|��坐标�p�，地物�c�d��{�，最后是调用IFeature对象�?font style="line-height: 1.3em" face="Times" size="3">Store()保存��d��的地物�?

上边的方法可以添加点地物�Q�接着看看下边的代码。看有什么不同：

public void AddPointByWrite()

     {

         IFeatureLayer l = MapCtr.Map.get_Layer(0) as IFeatureLayer;

         IFeatureClass fc = l.FeatureClass ;

         IFeatureClassWrite fr = fc as IFeatureClassWrite ;

         IWorkspaceEdit w = (fc as IDataset).Workspace as IWorkspaceEdit;

         IFeature f ;

         IPoint p;

         w.StartEditing (true);

         w.StartEditOperation() ;

         for (int i = 0 ; i< 100 ; i++ )

         {

              f= fc.CreateFeature();

              p = new PointClass();

              p.PutCoords (i,i);

              f.Shape = p;

              fr.WriteFeature (f);

         }

              w.StopEditOperation();

              w.StopEditing(true);

     }

代码中用�U�色标记的两行就是不同的代码�Q�其实他��是保存方式的不同而已。在�q�利用了IFeatureClassWrite 接口来保存数据。再看看下边的代码：

         public void AddPointByBuffer()

         {

              IFeatureLayer l = MapCtr.Map.get_Layer(0) as IFeatureLayer;

              IFeatureClass fc = l.FeatureClass ;

              IWorkspaceEdit w = (fc as IDataset).Workspace as IWorkspaceEdit;

              w.StartEditing (true);

              w.StartEditOperation() ;

              IPoint p;

              IFeatureBuffer f;

              IFeatureCursor cur = fc.Insert(true);

              for (int i = 0 ; i< 100 ; i++ )

              {

                   f= fc.CreateFeatureBuffer();

                   p = new PointClass();

                   p.PutCoords (i,i);

                   f.Shape = p;

                   cur.InsertFeature (f);

              }

              w.StopEditOperation();

              w.StopEditing(true);

     }
其实不同的地方就两句代码�Q�红色表�C�的。在�q�没有再定义地物接口了（IFeature�Q�，而是使用IFeatureBuffer 接口�Q�保存的时候是使用InsertFeature()保存�Q�这对大数据量处理的非常有好处。他是先把要��d��的保存到�~�冲区里。最后一�ơ性保存�?
二�?/font>��d��U?/strong>
��d��U�的�Ҏ(gu��)��跟添加点一��P��不同的只是地物类型不一栯��已�Q�我把代码脓(chu��ng)出来�Q�大家跟��d��点的方式�q�行�Ҏ(gu��)��。这样便于记忆。也有利于理解�?

     public void AddLineByWrite()

     {

         IFeatureLayer l = MapCtr.Map.get_Layer(0) as IFeatureLayer;

         IFeatureClass fc = l.FeatureClass ;

同一坐标�p�M��Q�由��L��两点计算地图旋�{角度(转蝲)

��剑��秋 — Wed, 25 Jun 2008 02:13:00 GMT

一、引�a�

在各�U?/span>GIS/GPS应用中，地图旋�{是不可或�~�的一部分�Q�尤其明昄��是用在实时导航，对象跟踪�{�应用方面。用来计��地图旋转时偏�{角的坐标�Ҏ(gu��)��动态和静态两�U�之分。动态在�q�里指的是在已知当前点的情况下，下一点的具体位置是不��定的；而静态指的是下一点的具体位置是确定的。动态的应用我们常见到的�?/span>GPS��D��、游戏中的赛�?/span>(多赛道、可转弯�{?/span>)以及调度�{�中的实时地图旋转，而静态更常见的是作�ؓ一�U�功能的演示�Q�如模拟��D��Q�模拟赛车等。地图旋转只有在同一坐标�p�M��q�行才有意义�Q�地图旋转角度的计算才有依据�Q�本文主要着重点在于如何由前后两点计��地图旋转角度，同时主要考虑动态的方式�Q�静态方式的旋�{地图原理是一��L��Q�就不分开介绍了�?/span>

二、约定和术语

²      参考坐标系�Q�本文所依据的坐标系为北�?/span>54下的依据高斯克吕格投影所建立的坐标系�Q�即高斯�q�面坐标�p�，它的囑փ�如图�Q?/span>

X代表为正北方向，Y代表正东方向�Q��ؓ了��y值都为正�Q�将�U�坐标��u西移500km�?/span>

²      正切函数是直角三角�Ş中，对边与邻边的比倹{��放在直角坐标系中（如图�Q�即 tanθ=y/x

其中tanθ的定义域为（-∏/2�Q?∏/2�Q�，值域�?/span>(-∞,+∞)

²         偏�{角：�U�定偏�{角�ؓ北偏东的角度�Q�将地图按照偏�{角进行旋转后��始�l�朝着�q�动方向行驶。在高斯�q�面坐标�p�M��Q�正北即�?/span>X��_��正东即�ؓY��_��所�?/span>tanθ�q�是�?/span>y/x�Q�只是角度的位置有了变化�Q�如图所�C��?br />

²         反正�?/span>�Q�函�?/span>y=tanx的反函数叫做反正切函�?/span>,记做:y=arctanx.
定义�?/span>:R�Q�值域:(-π/2,π/2)
三、计��偏转角

假设存在一起始�?/span>pntBegin�Q��ƈ且存在一个原点�ؓpntBegin的��^面坐标系�Q�同时约定要旋�{的角度�ؓrotateAngle,则下一�?/span>pntDest�Ҏ(gu��)��方位有几�U�情况，其示意图如下�Q�我们可以分�c�进行讨论：

l       �?/span>pntDest.x1>=pntBegin.x0,则该点在�W�一和第四象限，具体对应点�ؓpntDest(1)�?/span>pntDest(4),分别对应的北偏东角度�?/span>α(1)�?#945;�Q?�Q�，�Ҏ(gu��)��Y值的不同�Q�我们又可以分两�U�情况，

n       若pntDest.y>=pntBegin.y://在第一象限
rotateAngle=arctan2(fabs(p0.x-p1.x),fabs(p0.y-p1.y));

n       若pntDest.y rotateAngle=arctan2(fabs(p0.x-p1.x),fabs(p0.y-p1.y));
rotateAngle=∏-rotateAngle;

l       �?/span>pntDest.x1则该点在�W�二和第三象限，具体对应点�ؓpntDest(2)�?/span>pntDest(3),分别对应的北偏东角度�?/span>α(2)�?#945;�Q?�Q�，�Ҏ(gu��)��Y值的不同�Q�分两种情况�q�行讨论�Q?/span>

n       若pntDest.y>=pntBegin.y://在第二象�?br /> rotateAngle=arctan2(fabs(p0.x-p1.x),fabs(p0.y-p1.y));
rotateAngle= 2*∏-rotateAngle;

n       若pntDest.y rotateAngle=arctan2(fabs(p0.x-p1.x),fabs(p0.y-p1.y));
rotateAngle=∏+rotateAngle;

查询ArcIMS中的动态图�?引自ESRI北京论坛)

��Z��解决客户的问�? 捣鼓了一下arcims的动态图�?因�ؓ前后�׃��我十来个��时,所以还是想写下来和大家分��n,有不同意见欢�q�广泛交��?
一.关于��d��动态图�?/font>
�q�是个很不值得一提的问题,看到�q�个标题,估计很多老师和资�׃�h士都��x��砖头�q�来.大家�q�是耐心点儿,古典长篇名著�q�要从滚滚长江东逝水开始呢.我们也先弄个引子,��Z��充实一下篇�q?

1.修改AXL文�g
��d��动态图层有个前�?��是必须在AXL�?为MAP元素,��d��dynamic属�?�?

�q�个步骤在Author中无法完�?只能通过文本�~�辑器手工编辑了.��使用EmEditor或者VS.

2.动态添�?/strong>
通过发送ArcXML或者调用连接器中封装的对象,我们��可以动态添加指定的囑ֱ�,下面是��用ArcIMS Java Connector的例�?

(1)动态添加SHAPE囑ֱ�
.....
ShapeWorkspace shpw = new ShapeWorkspace();
shpw.setDirectory("D:\\WorkSpace\\sd");
shpw.setName("sde_ws-1");

map.addWorkspace(shpw);
Dataset data = new Dataset();
data.setName("地区边界");
data.setWorkspaceName(shpw.getName());

data.setType("polygon");
FeatureLayer fl = new FeatureLayer("2", null, null);
fl.setDataset(data);
fl.setName("地区边界");
fl.setVisible(true);
SimpleRenderer sr = new SimpleRenderer();
SimplePolygonSymbol sm=new SimplePolygonSymbol();
sm.setFillColor("255,0,0");
sm.setBoundaryColor("0,0,255");
sm.setFillType(SimplePolygonSymbol.SOLID);
sr.setSymbol(sm);

fl.setRenderer(sr);
map.getLayers().add(fl);
(2)SDE囑ֱ�
......
SDEWorkspace sdeWSP = new SDEWorkspace();
sdeWSP.setName("sde_ws-4");
sdeWSP.setInstance("port:5151");
sdeWSP.setServer("jerry");
sdeWSP.setPassword("sde");
sdeWSP.setUser("sde");
map.addWorkspace(sdeWSP);
Dataset data = new Dataset();
data.setName("SDE.地区边界");
data.setWorkspaceName(sdeWSP.getName());

data.setType("polygon");
FeatureLayer fl = new FeatureLayer("2", null, null);
fl.setDataset(data);
fl.setName("地区边界");
fl.setVisible(true);
SimpleRenderer sr = new SimpleRenderer();
SimplePolygonSymbol sm=new SimplePolygonSymbol();
sm.setFillColor("255,0,0");
sm.setBoundaryColor("0,0,255");
sm.setFillType(SimplePolygonSymbol.SOLID);
sr.setSymbol(sm);
fl.setRenderer(sr);
map.getLayers().add(fl);

�?动态图层的查询

1.�q�是从修改AXL文�g开�?/strong>

如果要��d��的动态图层可以被查询,比如Identify, �~�冲区查询等�{?必须具备一个前�?必须在AXL�?为MAP元素,��d��dynamicfeature="true">属�?�?

2.两个注意事项

�l�过反复��试,发现必须注意两点:
(1)执行查询�?必须��d��对于LAYER的DATASET的定�?而且,DATASET的workspace属性必��L��已经包含在AXL文�g�?
(2)如果不是直接发送ArcXML,那么查询之前需要Remove掉动态添加上�ȝ��所有workspace

3.执行查询的例�?/strong>
查询的应用类型很�?包括点击地图的Identify,�q�有图上的框�?圈�?多边形选择,甚至�~�冲区查询等�{? 有时候还需要结合属性where条�g的筛�?对于ArcIMS而言,都是
SPATIALQUERY. 下面��׃��Identify的点��L��询�ؓ�?

(1)直接发送ArcXML:











注意在LAYER的元素中��d��的DATASET的定�?其中,DATASET的workspace属性必��L��已经包含在AXL文�g的WORKSPACE�?什�?br /> 意思呢?��拿�q�个例子中而言,其中�?sde_ws-4"必须是在�q�个地图服务的AXL文�g中定义过的SDEWORKSPACE.
(2)使用Java Connector�E�序�q�行查询:
......
//注意在这里需要获取当前map中的workspace,赋给一个��时变�?然后从map中去�?br /> SDEWorkspace sdeWSP = new SDEWorkspace();
sdeWSP=(SDEWorkspace)map.getWorkspace(0);
map.removeWorkspace(0);
FeatureLayer fLayer=(FeatureLayer)map.getLayers().item(0);

//注意在这里必��d��明Dataset,�q�且赋予相应的Name, workspace,type�{�属�?其中workspace名称很重�?必须也是定义在AXL�?
//然后把Dataset对象赋给FeatureLayer对象
Dataset data = new Dataset();
data.setName("SDE.地区边界");
data.setWorkspaceName("sde_ws-4");
data.setType("polygon");
fLayer.setDataset(data);

com.esri.aims.mtier.model.map.layer.query.Filter filter= new com.esri.aims.mtier.model.map.layer.query.Filter();
Point pnt = map.toMapPoint(Double.parseDouble(x), Double.parseDouble(y));
double maxx = pnt.getX() + 0.0001;
double maxy = pnt.getY() + 0.0001;
double minx = pnt.getX() - 0.0001;
double miny = pnt.getY() - 0.0001;
Envelope envelope = new Envelope();
envelope.setMinX(minx);
envelope.setMinY(miny);
envelope.setMaxX(maxx);
envelope.setMaxY(maxy);
filter.setSpatialShape(envelope);
filter.setGlobalEnvelope(true);
filter.setBoundingEnvelope(true);
filter.addSubField("DIST_CODE");
filter.addSubField("NAME");
filter.setRelation(com.esri.aims.mtier.model.map.layer.query.Filter.AREA_INTERSECTION);
fLayer.getRecordset().clearRecordset();
fLayer.setFilterObject(filter);
map.refresh();
//执行完查询之�?如果有必�?��之前去除的workspace��d��到map�?
map.addWorkspace(sdeWSP);
......
4.常见错误信息
(1) Underlying input stream returned zero bytes
表明没有指定Layer的Dataset,或者Dataset中的workspace没有定义在AXL文�g�?
对于仅仅��d��动态图层而言,workspace的名字可以是��L��?而且可以不用定义在AXL文�g�?但是如果涉及到对于动态图层的查询,��必��L��意这一�?

(2) map.refresh()时�?提交到后台的��h��是GET_IMAGE而不是想要执行的GET_FEATURE
�q�个问题的原因是因�ؓ没有在查询之前去除map中包含的workspace

(3) ��d��了动态图层以�?无法查询其他固有的图�?br /> �q�个问题的原因同2,也是因�ؓ没有在查询之前去除map中包含的workspace.
�q�是个很奇怪的问题,毕竟没有涉及到对动态图层的查询,但是其他囑ֱ�昄��受到了动态图层的影响, anyway, �q�样做了以后��O(ji��n)K�?

ArcIMS中如何在同一囑ֱ�中做�~�冲选择

��剑��秋 — Sat, 15 Mar 2008 07:15:00 GMT

ArcIMS中如何在同一囑ֱ�中做�~�冲选择�Q?/p>
在javaConnector中如何在同个囑ֱ�中缓冲�ƈ选择要素。在同一囑ֱ�中选择出缓冲分析结果需要额外的步骤才能完成�Q�但是当选择囑ֱ�和做�~�冲的不是同一层时�Q�则不需要额外的步骤。一个典型的查询例子是这��L��Q�在San Jose市周�?公里内有多少城市�Q?
�q�程描述
步骤�Q?br /> 额外的步骤如下，需要创��Z��个新的层来用作buffer层。在filter选择中，如果buffer层和选择目标层是同一层时�Q�将��D��错误�l�果产生�?br /> 1.创徏一个连接�ƈ初始化一个Map对象。在Map.initMap()中LaodRecordset属性必��设�|��ؓtrue�?br /> map.initMap(connection,0,false,false,true,false);
2.创徏buffer层的引用�?br /> FeatureLayer fLayer = (FeatureLayer)map.getLayers().item(5); //buffer layer
3.创徏一个buffer层的复制层来作�ؓ选择的目标层。该新的复制层和原来的图层具有相同的LayerID,MaxScale,MinScale, 和Recordset
FeatureLayer tLayer = new FeatureLayer(fLayer.getID(),fLayer.getMaxScale(),fLayer.getMinScale());
tLayer.setRecordset(fLayer.getRecordset()); //tLayer is the target layer
4.创徏Filter�c�d��Buffer对象�Q��ƈ讄��他们的属性应用到buffer层上�?字串9
Filter filter = new Filter();
filter.setWhereExpression("NAME='San Jose'");
Buffer buffer=new Buffer();
buffer.setBufferUnits(Buffer.MILES);
buffer.setBufferDistance(8);
buffer.setPerformBuffer(true);
buffer.setBufferRegionSymbol(ps);
buffer.setBufferSelectionSymbol(ms);
buffer.setBufferTargetLayer(tLayer);
filter.setBufferObject(buffer);
fLayer.setFilterObject(filter);
5.查询�l�果被保存在一个名�U�Cؓ'bufferLayer'的层中�?br /> FeatureLayer resultLayer=null;
Recordset recordset = null;
for (int i=0;i if (map.getLayers().item(i).getName().equalsIgnoreCase("bufferLayer")){
resultLayer = (FeatureLayer)map.getLayers().item(i);
break;
}

使用ArcGIS Server Java ADF Manager创徏的Web Application中提供一个通用的工��h��Q�包含默认的8个地囑ַ��?包括4个Tool�?个Command).
打开模版产生的mapviewer.jsp文�g�Q�在�W?7行我们可以看到这个工��h��的定义：
xslFile="maptoolstask.xsl"/>

我们发现�Q�它�q�不是由a:toolbar和a:tool定义的，而是一个封装好的mapToolsTask对象�?br /> 通过查看faces-config.xml,我们看到mapToolsTask的定义如下：

mapToolsTask
com.esri.adf.web.tasks.MapToolsTask
session

webContext
#{mapContext}

事实上，mapToolsTask是在ArcGIS Server Java ADF 中已�l�封装好的com.esri.adf.web.tasks.MapToolsTask的一个实例�?br /> �c�M��于自定义Task的过�E�中实现TaskInfo的方法，我们可以也可以通过��个mapToolsTask实现一个TaskInfo来达到定制的目的。倍感方便的是�Q�在ArcGIS Server Java ADF 也同样封装好了一�?br /> com.esri.adf.web.tasks.MapToolsTaskInfo的类�Q�我们只需�l�承�q�个�c�d��修改其中的配�|�即可，举个最��单的例子�Q?br /> 1.新徏一个类MyToolsTaskInfo�Q��承自com.esri.adf.web.tasks.MapToolsTaskInfo�Q?/p>

package com.jerry.ags;
import com.esri.adf.web.tasks.MapToolsTaskInfo;
import com.esri.adf.web.tasks.MapToolsTaskConfig;
public class MyToolsTaskInfo extends MapToolsTaskInfo{
public MyToolsTaskInfo(){
MapToolsTaskConfig tc=new MapToolsTaskConfig();
tc.setTools("IDENTIFY,ZOOMIN,ZOOMOUT,");
super.setTaskConfig(tc);
}
}

在这个简单的例子中只包含一个构造函敎ͼ�在构造函��C��我们首先创徏一个import com.esri.adf.web.tasks.MapToolsTaskConfig的实例，�q�调用它的setTools�Ҏ(gu��)��Q�意为在工具条中只包
�?IDENTIFY,ZOOMIN,ZOOMOUT"三个工具。最后通过调用基类的setTaskConfig�Ҏ(gu��)��这个com.esri.adf.web.tasks.MapToolsTaskConfig实例生效�?br /> 2.在face-config.xml文�g中添加如下配�|�：

myToolsTaskInfo
com.jerry.ags.MyToolsTaskInfo
session

3.修改mapviewer.jsp文�g�W?7行工��h��的定义中taskInfo属性的�?/p>

xslFile="maptoolstask.xsl"/>

4.重新部��v�q�启动应用，我们看到工具条中��只出现三个工具�Q�依�ơ是IDENTIFY-ZOOMIN-ZOOMOUT

补充
1.�怿�定制模版应用的工��h��q�有更�ؓ灉|��的方法，比如直接自定义Tool,Command�Q��ƈ通过a:toolbar,a:tool,a:command�{�标�{�֮�义来替代a:task。可以参考与�q�部分内容相关的资料�?/p>
2.MapToolsTaskInfo�l�承自com.esri.adf.web.data.tasks.SimpleTaskInfo�Q�因而可以通过实现TaskInfo接口中定义的getActionDescriptors()�Q�getToolDescriptors()�{�方法进行更复杂的定制�?br /> 比如�Q�我们希望修改点��L��询�ؓ拉框查询�Q�可以修改MyToolsTaskInfo 的实现程序如下：

package com.jerry.ags;
import com.esri.adf.web.tasks.MapToolsTaskInfo;
import com.esri.adf.web.tasks.MapToolsTaskConfig;
import com.esri.adf.web.data.tasks.TaskToolDescriptorModel;

import com.esri.adf.web.faces.event.ClientActions;
import com.esri.adf.web.tasks.MapToolsTask;
public class MyToolsTaskInfo extends MapToolsTaskInfo{
private TaskToolDescriptor[] taskTools=new TaskToolDescriptor[3];
public MyToolsTaskInfo(){
MapToolsTaskConfig tc=new MapToolsTaskConfig();
tc.setTools("IDENTIFY,ZOOMIN,ZOOMOUT,");
super.setTaskConfig(tc);

taskTools[0]=new TaskToolDescriptor(MapToolsTask.class,"identify","拉框查询",ClientActions.MAP_RECTANGLE);
taskTools[0].setRendererType(TaskToolDescriptor.IMAGE_RENDERER_TYPE);
taskTools[0].setDefaultImage("http://jerry:8000/gs/images/tasks/maptools/identify.png");
taskTools[0].setSelectedImage("http://jerry:8000/gs/images/tasks/maptools/identifyD.png");
taskTools[0].setHoverImage("http://jerry:8000/gs/images/tasks/maptools/identifyU.png");

taskTools[1]=new TaskToolDescriptor(MapToolsTask.class,"zoomIn","攑֤�",ClientActions.MAP_RECTANGLE);
taskTools[1].setRendererType(TaskToolDescriptor.IMAGE_RENDERER_TYPE);
taskTools[1].setDefaultImage("http://jerry:8000/gs/images/tasks/maptools/zoomin.png");
taskTools[1].setSelectedImage("http://jerry:8000/gs/images/tasks/maptools/zoominD.png");
taskTools[1].setHoverImage("http://jerry:8000/gs/images/tasks/maptools/zoominU.png");

taskTools[2]=new TaskToolDescriptor(MapToolsTask.class,"zoomOut","�~�小",ClientActions.MAP_RECTANGLE);
taskTools[2].setRendererType(TaskToolDescriptor.IMAGE_RENDERER_TYPE);
taskTools[2].setDefaultImage("http://jerry:8000/gs/images/tasks/maptools/zoomout.png");
taskTools[2].setSelectedImage("http://jerry:8000/gs/images/tasks/maptools/zoomoutD.png");
taskTools[2].setHoverImage("http://jerry:8000/gs/images/tasks/maptools/zoomoutU.png");
}

public TaskToolDescriptorModel[] getToolDescriptors(){
return taskTools;
}

}

注意其中的taskTools[0]=new TaskToolDescriptor(MapToolsTask.class,"identify","拉框查询",ClientActions.MAP_RECTANGLE);
