I have successfully produced a L4A mask, and I used it to generate a L4B map. However, the final L4B map (stored in the folder .l4b/./LEGACY_DATA/IMG_Data) output by the system is not correct. Indeed, blank spaces are left between the original tiles as shown in the attached image.
Notice that the “tile by tile” results (stored in the folder .l4b/./TILES) seem correct.
Has anyone already experienced this problem?
