Land change detection
Land Change Detection
Sentinel satellites provide support to land monitoring services and will ensure frequent and systematic coverage to support the mapping of land cover, classification and change maps, and accurate assessment of geophysical parameters.
With land change maps it is easy to identify developments in the land - e.g. new structures being built, deforestation happening, etc. As different types of land (e.g. arable land, forest, pastures, urban areas) have different patterns of index change (e.g. EVI, NDVI, etc.). By observing greenness time series patterns it is possible to detect changes. Operators can then analyse the results closely by observing original images and decide on required action
Land Change Maps
Satellite image data is highly useful for creating or updating base maps and detecting major changes in urban land cover and land use.
Satellite imagery provides support to land monitoring services and ensure frequent and systematic coverage to support the mapping of:
- Land cover development
- Classification and change maps
- Environmental analysis
- Irrigated landscape mapping
- Carbon Storage and Avoidance
- Yield determination
- Soils and Fertility Analysis
- And other accurate assessment of geophysical parameters
