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https://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

    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);
            
        }
        
    }
