I'm trying to recreate real terrain map but I have faced some difficulties. My goal is to use Google Earth and Google Terrain overlay in combination with AATF Power Toolkit (AATF PT) to recreate real terrain. I decided to go with 6 x 5 km map. I followed "Creating Maps from SRTM Data - Tutorial" and sucessfuly obtained XDM map with size of 1 degree by 1 degree square where bottom left corner coordinates are 43 deg. 47' 10" LAT and 18 deg. 58' 26" LONG. Next step is creation of elevation map in AATF PT and that is where real problems start.
1) When "Map Production Information" dialog is shown if I accept all default values and simply clik "OK" button, I get 50 x 50 km map. So far so good. But, as I already stated, I want smaller 6 x 5 km map. After adjusting map dimension in "Map Product Information" dialog, the resulting smaller map is distorted along upper and right edge.
I am not sure why this disstortion appears? Also some of contours are disconnected. Is it a bug or maybe I need to change some of the default parameters in Map production Information" dialog?
2) Resulting map of 6 x 5 km have 2400 x 2000 pixels. Doing simple math I concluded that 1 km = 400 pixels. After adjusting Google terrain map (which have 20 m contour lines) to have same 1 km = 400 pixels ratio, I would expect to get exact match after I overlay Google terrain map over AATF contour map in drawing program, but it is not a case. They are comparable but not (exactly) matching. I assume solution could be in adjusting map construction parameters in AATF PT "Map Production Information" dialog, but I don't know how to obtain these parameters from Google Earth.
3) After I convert my map bottom left corner coordineates of 43 47' 10" LAT and 18 58' 26" LONG in seconds I get 157630 LAT and 68306 LONG which does not correspond with 154800 LONG and 64800 LAT which are default values in "Map production information" dialog after opening XDM file. I wonder why these values are not matching and which values should I enter?
4) Having all of the above in mind, does anybody know how to recreate real terrain using Google Earth and AATF PT?
Many thanks in advance.
