Flex 加载shp

至于gis格式比较常见的shp是开源的，网上开源的as代码也很多 这个支持的shp算比较好的 源码在这边http://files.cnblogs.com/files/haibalai/shp.rar，加载shp必须勾选两个文件shp和dbf，shp是存取图形geometry信息。dbf是属性信息

我这边写了个工具类调用

 package widgetscadastre.DwgLoad
 {
     import com.esri.ags.Graphic;
     import com.szpl.extension.util.shp.dbf.DbfHeader;
     import com.szpl.extension.util.shp.dbf.DbfRecord;
     import com.szpl.extension.util.shp.dbf.DbfTools;
     import com.szpl.extension.util.shp.shp.ShpPolygon;
     import com.szpl.extension.util.shp.shp.ShpReader;
     import com.szpl.extension.util.shp.shp.ShpSymbol;
     import flash.events.Event;
     import flash.utils.ByteArray;
     import mx.collections.ArrayCollection;
     /**

     public class ShpLoadTool
     {

         public function ShpLoadTool()
         {

         }

         private var _callFun:Function;
         public function shpLoad(shpByteArray:ByteArray, dbfByteArray:ByteArray,callFun:Function):void
         {
             _callFun = callFun;
             var index:int = 0;
             const array:Array = [];
             const shpReader:ShpReader = new ShpReader(shpByteArray);
             const dbfHeader:DbfHeader = new DbfHeader(dbfByteArray);
             while (shpReader.hasMore())
             {
                 var shpPolygon:ShpPolygon = shpReader.readShpPolygon();
                 var dbfRecord:DbfRecord = DbfTools.getRecord(dbfByteArray, dbfHeader, index++);
                 array.push(new Graphic(shpPolygon, new ShpSymbol(), dbfRecord.values));
             }

             _callFun.call(null,array);

         }

     }

 }
