Upcoming products :

  • Global agro-environmental stratification Database
  • Multi-resolution annual cropland maps
  • Country Land cover analysis database for selected areas
  • Time series of satellite derived parameters
  • Hotspot maps identifying zones with high variability and agro-environmental changes and description
  • Maps of potential/actual yield and gaps
  • Training materials

These products will become available through SIGMA’s data management facility.
This will consist of 3 main components:

  • A product Distribution facility, being a catalogue of collected and produced data
  • A product Analysis Facility, allowing to analyse remote sensing date
  • A product Evaluation Facility, to enable cross-checking of produced maps with expert knowledge and other data sources

The components will be based upon existing solutions developed by the SIGMA partners IKI, IIASA and VITO.
Available data resources are:

  • GeoWiki
  • Data catalogue portal
  • VEGA Service
  • Africa portal
