Data archive

Acess to historic and current satellite images and their products from the area of the Czech Republic in the period of vegetation season.

Satellite data archive

Broad data archive containing current and historic images is a basic prerequisite for any research done over remote sensing data, enabling creation of various temporal analysis. Data is available after atmospheric corrections for consecutive processing steps including unsupervised and supervised classifications, calculation of vegetation and other indices. Current data and their comparison with the historical images help to cover the trends in landscape development and provide an overview staus of objects of interest - vegetation, water areas, built up areas, etc.
