Study of vegetation and soil types
This service provides for the production of image cartography to assess the status of different species of vegetation, as well as classification of land use, based on the calculation of a variety of indexes. To find out more, see the “Shop” section.
Production of Digital Elevation Models
Production of Digital Elevation Models using satellite imagery (RADAR).
Satellite imagery orthorectification
Processing of pairs of images acquired by orbital sensors for the production of orthorectified image cartography.
Satellites provide much more information than could be obtained on the ground, alone. The use of specific techniques allows the spatial representation of these data in thematic charts (eg: surface temperatures, ocean color, presence and height of ice, tides, etc.)
The use of multispectral imagery currently makes it possible to estimate the bathymetry of shallow areas (up to 30 meters of depth) with sufficient precision to study the hydrodynamics of large coastal areas, natural bars and coral reefs. This type of data can be used for environmental studies, planning engineering projects or integration in nautical charts of areas that are difficult to access by echosounders. The spatial resolution varies between 0.40 - 10 meters, depending on the types of sensor used.Taking into account the specificity of the projects, multispectral cameras installed in autonomous flight vehicles can be used.
