METHOD FOR GENERATING A CARTOGRAPHY OF A GEOGRAPHIC AREA

摘要

A method is provided for generating a cartography of a geographic area, including a step of obtaining a satellite image providing a morphology of obstacles in certain geographical positions of the area, a step of obtaining first data for the altitude of peaks of the obstacles relative to sea level, a step of obtaining second data for the altitude of the ground for the geographical positions relative to sea level, a step of calculating the height of the obstacles via the difference between the first and second data, and a step of generating the cartography by combining, in each geographical position, morphology of the obstacle with the height of the obstacle.

1. A method for generating a cartography of a geographic area, the method comprising:
a step of obtaining a multispectral satellite image supplying morphologies of obstacles at certain geographic positions in said area; a step of obtaining first data on altitude of the tops of said obstacles relative to sea level; a step of obtaining second data on altitude of the ground at said geographic positions relative to sea level; a step of calculating the height of said obstacles by the difference between said first and second data; and a step of generating said cartography by associating, at each of said geographic positions, said morphology of the obstacle with the height of the obstacle.
