Edi, its not like that, you provide shp2img a map file, bounding box, height and width of output file, and it produces a image made of all the tiles that land in that bounding box

So i need to merge them. And im still working on it cuz i dont know how many tiles should merge to create a bigger one that will be displayed at bigger scales (still confused how to find this scale for example 1:5000 or 1:100000 i dont know it) Regards Edi Karadumi -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/gdal-dev-Raster-Strategies-Examples-tp5364468p5377105.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
