Raster maps and datum
Hi all. I'm new to this forum, looking for help in the use of raster maps on Globalmapper. I searched the web for detailed maps of Morocco. I could ind a good amount for free at this site http://www.lib.utexas.edu/maps. There are severals. I am interested in 1:50.000 even if dated. The orographic contours definitely are not changed and the existing roads probably traces the old ones or are very closed. http://www.lib.utexas.edu/maps/ams/morocco_50k/ for many maps are available projection data and its characteristics, this is an example (http://www.lib.utexas.edu/maps/ams / morocco_50k/txu-oclc-6589697-29-11-4a.jpg) then I can use a UTM. There is no mark about to the geodetic datum used for the generation of the map, in particular I would be interested in the transformation parameters into WGS84. If someone has already faced similar problem and solved it, I'd be grateful.
