• At the ICGC, we are updating our Hypsometric map at a scale of 1:250,000 to include changes in toponymy, administrative boundaries and planimetric elements.

A hypsometric map is a cartographic representation that shows the variations in terrain altitude, including bathymetric ones, through a range of colors that helps to understand the morphology of the relief, with thematic coherence.

Hypsometric maps are generated from altimetric data captured with technologies such as LiDAR (Light Detection and Ranging), which allow digital terrain models to be obtained with high precision. Altimetric data are processed with GIS programs, which integrate LiDAR measurements and other sources to generate a digital terrain model (DTM).

From this model, cartographic representation techniques, such as color assignment according to altitude intervals and shading, are applied to generate the final hypsometric map.
