Here is a file with tutorial that allows people to make custom Sentinel tactics environment tiles using the freeware program Inkscape. To use it, unpack the file using Winrar or Winzip, download and install Inkscape and open the file. In this version I estimated the size of the tiles to be 150mm and can adjust that easily if the size varies from that. The .rar file also contains the printscreen from google maps that was used for the earlier posted example, so as to provide some practice material. Enjoy!
Mind posting a few pics of the result so we know what we'd be getting ourselves into without installing and unzipping and whatnot? The link in your quoted paragraphs is broken for me.
This is kind of a bland example using a printscreen from google maps, but in essence you can insert any picture underneath the grid. After that it is just a matter of adjusting the dots.
