Hi: I am confusing with the garss. If I want to handle a tiff image and I donot know its wide(Amercia or the France),so what to do next? Should I create a new location and mapset and write it to the .grassrc file and delete it after my process? If so,how to make the commond? For example,I want to do a buffer,the basic commond is "r.buffer........",should I do some initialization work "g.region....."or others like this? Since I provide a interface for other clients to handle there data use the grass in my server,I am not sure how to config the grass,the location . the mapset? Looking forward some one can provide a clear suggestion! ================= apachemaven 2009-06-08
