I followed matt peddlestons videos on you tube and had it playing/replaying while carrying out the steps ,used panorama viewfinder for .hgt files download made the DEM file with STRM file inside it put the .hgt file inside Idone my billing account , set my static maps got api key for google , got my coordination long and latitude for port Cartier (hint hint) done all that put the api into tools bit , but nothing came up , I restarted my game but still nothing , just the green grass . when i click to add the data my landscape goes white then black and kicks me off and does the same for generating background terrain.
I feel like done something somewhere wrong but not sure , hence fourth i turn your guys knowledge is there a better way or did I miss something critical . I tried 3 or 4 times to get but it wouldnt play ball
thanks for any help or advice
Lets treat and troubleshoot the Google Overlay and SRTM/DEM issues seperately.
For the DEM, are you absolutely sure that you have the correct DEM file(s?) for your route area? The .hgt file will be named for the northernmost border of DEM coverage in the file (line of latitude) and the westernmost border (longitude). If your route origin point is in Port-Cartier, the file you would need in your Railworks/DEM/SRTM file would be " N51W067.hgt "
You should have all of the appropriate .hgt files to cover your entire route inside the SRTM folder.
Another common mistake is when creating your route, and setting the route starting point, make sure that you have entered the correct values as shown in Google Earth. (eg: Latitude: 50.02xxx , Longitude: -66.88xxx ). If you get those backwards, or forget the " - ", then your route and DEM data will be in completely different places.
To generate your distant terrain, you MUST be in your route's " 0,0 " tile, and with the appropriate DEM files
As I side note, the files from panorama viewfinders are of the '3 arc second' resolution. This means that the contours of the ground are extrapolated from points every 270 feet across the surface of the earth. In mountainous areas (or any area that isn't as flat as a pancake) this means that much of the elevation data is approximated. You will find that rail right of way embankments, river and ocean shores, cuttings and fills along the right of way, and hillside angles are quite a bit different than what is actually there for topography in real life. It is a bit more of a process to download and convert, but there are 1 arc second files available for free from the "open.canada.ca" Canadian Government site. These are made from data sampled every 90 feet, and give a much better representation of the real topography.
