Vegetation index monitoring
As part of the PADER program, calculation and evolution of the vegetation index in northern Cameroon between 2008 and 2018.
Nature likes to hide from our eyes.
As a GIS engineering firm, MAPTOGIS supports projects in land observation and management. With a comparison of ground control points, we analyze remote sensing data to produce geographic indicators from observations from different sources (satellites, planes and drones).
It offers more economical solutions than more traditional means (single field surveys for example). In addition, for a certain number of cases, remote sensing remains the only method to deal with problems which cannot be solved by conventional means (physically inaccessible places for instance).
MAPTOGIS has an Earth observation and spatial imagery analysis service which covers a wide range of applications:
- Natural land use
- Hydrology and water resources management (IWRM)
- Land use plans (LUP)
- Evolution of the vegetation indices
- Land degradation
- Management of renewable resources
- Crop identification and monitoring
- Nuisance detection (pollution, pests in crops)
- Urban and peri-urban developments
- ...and many others...
The emergence of new supports such as those of the European Space Agency (ESA) and its mission Copperniccus Sentinel 2 and 3 allow free acquisition of high spatial resolution images (10 m) with a very short revisit period (5 days ).
The MAPTOGIS team observes and analyzes the images of a large number of satellite sensors with different solutions, proprietary or open source, allowing us to have access to a wide range of technological tools.
