Remote sensing
According to the Spanish National Geographic Institute (IGN), remote sensing is the technique for acquiring data from the earth’s surface through sensors installed on space platforms. The electromagnetic interaction between the ground and the sensor generates a set of data, which is subsequently processed to gather interpretable information from the Earth.
There are currently a wide range of technology systems available, enabling this technique to be used in different applications, which are all expanding rapidly. Creativity is the only limitation. These include:
- Crop management and monitoring (precision agriculture)
- Quality control for power lines, photovoltaic power stations and wind farms
- Measurements of bulk material or industrial plant profiles
- Fast, accurate 3D laser scanner representation of cultural elements
- Tree density analysis
- Fire surveillance, border control or rescue for land, sea and/or air vehicles
- Precision mapping and photogrammetry
- Transport infrastructure mapping, road surface measurements, 3D point cloud city models in different operating modes: static or dynamic
