ABSTRACT
The IMPACT Toolbox has been developed by the European Commission's Joint Research Centre (JRC) with the goal to create a specific tool for the assessment of forest disturbances with remote sensing imagery. It contains tools related to (pre-) processing and analysis of medium to high resolution satellite imagery, specifically from the Sentinel-2, Landsat and RapidEye sensors.
IMPACT is an open source, free software based mainly on GDAL libraries and GDAL and Python scripting, flanked by intuitive (ExtJS, Openlayer and Mapserver) graphical user interfaces. It can be used as it is or adapted to the specific needs of each user.
IMPACT has tools for the import and calibration of satellite images as well as handy basic features for image mosaicking, image sub-setting by vector AOIs, pan-sharpening, and statistics extraction. Some main features contain different image classification methods, a linear un-mixing approach and a tool for the calculation of indices related to land cover analysis. All processes can be launched in "batch mode". IMPACT provides the user with the option to work with a pixel-based or an object-based (through image segmentation) approach, or a combination of both.
The main scope of IMPACT is the assessment of land cover and land cover changes, with specific applications regarding changes in forests, i.e. deforestation, forest degradation, forest regrowth. However, the tool can be readily used also in the context of other remote sensing - based research issues.
Several exercises are foreseen for the course, including the creation of a forest mask and the usage of the mask during the analysis of forest cover change. For both steps Sentinel-2 and Landsat data will be used.
