I am using java bindings to read in some metadata from image files. I have a check for images that are in EPSG:4326 (if not I warp them). However I have an image which I know is EPSG:4326 that has the following: "GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG\","7030"]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","4326"]]"
This is the constant from gdal I am using to compare: org.gdal.osr.osrConstants.SRS_WKT_WGS84 = "GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG\","7030"]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]],AUTHORITY["EPSG","4326"]]" So obviously when I do a string comparison the two strings do not match. 1. my file is marked wrong and I am hosed. This is tough cause I have thousands of these files. 2. There is a much better way to look at the images projection string to determine that it is EPSG:4326 and not some other projection. I also have file that are in a Transverse Mercator projection and its projection string contains "EPSG 4326", so I know that I cannot just check for that in the projection string. So in the end my question is this: how can I tell from the projection string metadata that I get from a GDAL Dataset object (Java) if it is EPSG:4326. thanks
