I have taken the time to download the SRTM-30 data which the Help file says is better than the GTOPO30 data. to get rid off the overlay information (like a grid) go to Modify -> Map Marginalia and surpress the labels and grid, otherwise the saved image will have those labels saved with!Īlthough MicroDEM is a little unstable it does make nice grayscale images. If you do a zoom on microdem-dem data and you save your imaghe afterwrads it will be of much better quality then if you saved the file and do a zoom later with photoshop. (remark the GTOPO Files are not of such a good quality! heightmaps are much more precise and better for resulting mountains, search for those hgt files, i've got some beuatifull results with 'the alpes' (=mountains in italy)) (the quality can be 1inch 10-30meter precise) Load this map via editor or play railroads. Copy-paste this image into your map_railrtoads.targa file on the height map section Save the image as targa-data (or other) from -30 to -2000 (this will give a brighter light grey) Adapt the zRange (i do this, because i think the result is too black) -> in Specified change the minimum z-range value fe. File -> Open DEM (select your saved file)
