Hello i was wondering if ii is possible to merge multiple maps in 1 map i do have 5 maps ( canada north , canada south , canada east , canada west ) which i want to get 1 map i try with GMapTool and i have an error since the mapset ( name of the blocks ) are the same from 1 map to the other one ex: canada north have a file name 63240001.img,63240002.img,63240003.img,63240004.img as well as canada south and the other one too . so is there a way to rename the (little files img ) inside canada north .img? or is there a way to get 1 main img file ? thanks in advance
