[求助] 知道投影信息怎么生成经纬度网格
USGS的土地利用分类数据,给出了投影信息为:<br/><p>
The data dimensions of the Lambert Azimuthal Equal Area projection for the North America land cover characteristics data set are 8,996 lines (rows) and 9,223 samples (columns) resulting in a data set size of approximately 83 megabytes for 8-bit (byte) images. The following is a summary of the map projection parameters used for this projection:</p><p> Projection Type: Lambert Azimuthal Equal Area </p> Units of Measure: meters <p> Pixel Size: 1000 meters </p><p> Radius of sphere: 6370997 m </p><p> Longitude of origin: 100 00 00 W </p><p> Latitude of origin: 50 00 00 N </p><p> False easting: 0.0 </p><p> False northing: 0.0 </p><p> XY corner coordinates (center of pixel) in projection units (meters): </p><p> </p><ul> Lower left: (-4487000, -4515000) <p> Upper left: (-4487000, 4480000) </p><p> Upper right: (4735000, 4480000) </p><p> Lower right: (4735000, -4515000) <br/></p><p><br/></p><p><br/></p><p>我想知道每个网格点的经纬度坐标,也就是生成一个二维的经纬度坐标数组。有高手知道怎么处理。非常感谢!<br/></p></ul><br/> |
