基于Flex/Flash的GIS类库

今天和地大的宝才聊天，又得知了几款对基于flex的GIS插件。

1）Vanrijkom-flashlibs 基于flex的shapefile转换库

2）MapShaper （基于flash的shapefile编辑及简化类库）

PS：同时，向大家推荐shp2kml，如果你是新手，又想通过kml表现自己的地图，可以试试这款软件，它完全免费。而且可以制作比较专业的kml文件并叠合到Google Earth上面。

Shp2kml is a stand alone tool that transforms GIS layers to Google Earth. It uses as input the most common format file for GIS (ESRI shapefile) and generates a KML File.

Google Earth requires coordinates to be in Lat/Lon and referenced to the WGS84 datum. Shp2kml is able to transform the coordinate system. The input file can be Lat/Lon (Geographic) or UTM (Projected) coordinate system. Also shp2kml will change datums if required. It contains a list of around 200 datums.

Some of the supported features are:

* Lat/Long or UTM (meters)
* Any Datum
* Point, Lines, Polygons
* Symbol properties: by Single Symbol, Unique value, Graduate Value
* Labeling from attributes table
* Balloon creation from attributes table

我将alachua的shapfile数据转换为kml，然后叠加在Google Earth上。
