Environmental monitoring

Satellite image analysis

Satellite images at the service of environmental monitoring

Remote sensing aims at studying the surface of the earth from images taken by airborne cameras placed in a drone, an airplane or a satellite. The results of the latter make it possible to improve the inventory, management and forecasting of natural, agricultural and environmental resources, by making available to managers and decision-makers, localized information collected in the field that sometimes turns out to be costly. MAPTOGIS engineers are at your disposal to define the needs for satellite image analysis.

Land use

Satellite images to define natural occupations or land use by humans. The precise knowledge of these is a crucial issue for many operational applications, particularly in land management.

land use classification


Vegetation and soil indices make it possible to identify and monitor environmental dynamics and soil degradation. These indicators support your actions related to climate change.

vegetation indices ndvi


It makes it possible to highlight the evolution of phenomena through the comparison of data from classifications of satellite images on the same area for a given time interval, and to analyze the factors acting on the evolution of ecosystems.
