The PrimaryRadar Euroscope plugin simulates a primary radar, taking into account terrain, range and other parameters.
Terrain data should be converted from the Geotiff format to the format described on the above image using the /converter tool.
The program creates a /geodata folder on the working directory with a geo.dat and a meta.json file inside:
geo.dat: Vec that contains all rows of the geotiff grid joined together in one single vector.meta.json: contains the data necessary to translate real-life coordinates into individual pixels on the grid, as well as it's size.
