CadasterENV – Overview

CadasterENV is the fourth project within the overarching LISA initiative and funded by the GMES Service Element within the Earth Watch Program of the European Space Agency (ESA). The project has been started in August 2015 and will run till December 2017. Within the first two LISA projects the land cover mapping was based on orthophotos and laser scanning data, whereas in the third project - CadasterENV Austria - the map production relied on the Pléiades and WorldView-2 satellites, which acquire very high resolution (VHR) satellite imagery.

For the current CadasterENV project a prototyping phase served to develop a sound method for the realisation of the five foreseen products. For this purpose imagery of the SPOT-5 Take 5 experiment was used to simulate the image time series of the Sentinel-2 satellite constellation, whose imagery became publicly available later in the project. The SPOT-5 Take5 data were supplemented with Landsat 8 data, where necessary. For the second project phase the developed methods are adapted for use with the data acquired by the Sentinel-2 satellite, which provides images with a spatial resolution of 10 m. Sentinel-2 acquires images for the same footprint on Earth every five to ten days. This dense time series of data considerably facilitates the development of an effective land cover monitoring methodology within the CadasterENV project and therefore allows better identification of land cover changes.

The following objectives shall be accomplished within CadasterENV:

  • The integration and full exploitation of Sentinel-2 imagery in the Land Information System Austria (LISA)
  • The preparation of a high resolution land cover map for the whole of Austria
  • The enrichment of the very high resolution LISA land cover map (10,000 km²) with Sentinel-2 based information
  • The successful detection of different land cover / land use change types:
    • long-term changes (e.g. new buildings, roads)
    • seasonal changes (especially in agriculture)
    • continuous changes (e.g. forest growth)

Similar to the previous projects a representative group of stakeholders from Austria and other European countries is involved in CadasterENV. Their background comprises different disciplines as for example agriculture, forestry, environmental protection and conservation, spatial planning and water management as well as natural hazard management.

Further information about the project will be provided with dedicated newsletters (subscribe here). They can also be found in the downloads section.
