In projected mode, you have to specify a map profile (i.e. a map projection). You also need to tell osgEarth the spatial reference of your feature data if it differs from that of the map. For example: <map name="demo" type="projected&quo…

在GIS软件的开发中,经常用到开源库GDAL读取Shp数据,当shp数据中包含投影信息时,可能会遇到“Unable to open EPSG support file gcs.csv”错误提示,该错误是由于没有设置“GDAL_DATA”引起的. 1.Shpefile文件组成 Shapefile文件指的是一种文件存储的方法,实际上该种文件格式是由多个文件组成的.其中,要组成一个Shapefile,有三个文件是必不可少的,它们分别是".shp", ".shx"与 &qu…
The OGRDataSource supports executing commands against a datasource via the OGRDataSource::ExecuteSQL() method. While in theory any sort of command could be handled this way, in practice the mechanism is used to provide a subset of SQL SELECT capabili…
