Image-maps are elaborated using one or more images from remote sensors, generally from the LANDSAT satellite in color composite (RGB-543). The images are georeferenced in alignment with the 1:250.000 scale mapping base in digital medium, and then, mosaicked and cut according to the systematic topographic mapping format.

In support of field investigations, image-maps contribute to the updating of cartographic databases and thematic maps.
