我正在使用mapdotnet服務爲我們的gis應用程序加載shapefile,而此mapdotnet服務需要proj4的詳細信息。我從spatialreference.org獲得它們,但對於this projection,proj4的詳細信息是blank。我如何從.prj文件或shapefile中獲取proj4的詳細信息?如何從shapefile的.prj文件獲取Proj4細節?
下面是shape文件的.PRJ:
PROJCS["NAD_1983_HARN_WISCRS_EauClaire_County_Feet",GEOGCS["GCS_North_American_1983_HARN",DATUM["D_North_American_1983_HARN",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",394000.0],PARAMETER["False_Northing",300812.797],PARAMETER["Central_Meridian",-91.28888888888889],PARAMETER["Standard_Parallel_1",45.87228112638889],PARAMETER["Scale_Factor",1.000035079],PARAMETER["Latitude_Of_Origin",45.87228112638889],UNIT["Foot_US",0.3048006096012192]]
這樣的GIS重量級問題可能會得到更高級別的專家關注[GIS Stack Exchange](http://gis.stackexchange.com/)。 – 2014-06-18 16:14:47
