Interaction Point, een producer of games, comissioned Red Geographics to produce a detailed terrain map of Europe, Asia and North Africa. This map will be used for “Kingdoms of Legend“, a game in an alternative historic setting.
The map uses the Hypsometrische Natural Earth by Tom Patterson, upsampled to the desired resolution, combined with a shaded relief image generated from GMTED elevation data and water (oceans, lakes and rivers) from the Natural Earth vector dataset. This is all combined in Photoshop and then reprojected to a Mercator projection using Geographic Imager.
The final resolution is approximately half a mile per pixel, by upsampling the hypsometric layer in small increments the overall quality is maintained to a degree. Then the overlay with the more detailed relief image causes the overall quality to be as high as possible.
