Land Use /Land Cover and Change

The  Land Use /Land Cover and Change products presents the status of, and changes in, land use and land cover. The information is derived from high resolution (HR) satellite data of a spatial resolution between ten and thirty meters.

The Land Use/ Land Cover Status product uses a (hierarchical) land use/ land cover classification scheme, where land cover and/or functional use of land is presented at a granularity level that matches that of the satellite data. 

The Land Use/ Land Cover Change product shows the conversion of land use/ land cover from one class to another between two points in time. The classification scheme for a status and a change product can be adapted to user requirements.

Land use/ land cover and change maps provide fundamental base information for a wide variety of forest monitoring and spatial planning tasks.

The products enable an accurate assessment of forest extent, loss and gain, and to identify areas of deforestation. They can also be used in combination with emission factors (EF) to assess the greenhouse gas (GHG) emissions associated with land and forest change:

  • Assessment of Activity Data for REDD+
  • Analysis of Degradation and deforestation
  • Sustainable Forest Management (SFM)
  • Forest Management / planning
  • Planning of Forest Landscape Restoration (FLR)

Identification of Drivers of Deforestation and Forest Degradation.

PRODUCT SPECIFICATIONS

CONTENT

  • Detailed mapping of land use / land cover into classes such as forest land, crop land, grassland, wetland, settlement.
  • Changes can be mapped between two or more points in time, showing changes from one type of land use to any other type of land use, or vice versa.

GEOGRAPHICAL COVERAGE

Regional, National, Sub-national, Local

TEMPORAL COVERAGE & FREQUENCY

Historical data and/or specific dates (e.g. 2010) can be used.

Continuous update is possible (e.g. every 12 months, 5 years), depending on availability of satellite data.

EO DATA AND SPATIAL RESOLUTION

High resolution (HR) satellite data e.g. Sentinel-2 with 10m resolution. Historic Landsat data with 30m resolution.

ACCURACY

Overall thematic accuracy: > 85 – 90%.  Positional accuracy: < 1 pixel of source imagery.
