Abstract:
Verification of High Resolution Layer (HRL) of Permanent Grassland TTP / Grassland was conducted on NPPC - VUPOP according to the current methodo-logy. „Guidelines for verification of High Resolution Layers produced by the CLMS (Copernicus Land Monitoring Service) as part of the 2015 reference year pro-duction“. Verification was done by two methods: a general overview of HRL Grassland data quality and using the "Look and Feel" method (for the recommen-ded six strata and two types of errors Comission and Omission). Verification was carried out visually in GIS environment interpretation and comparison HRL Grassland with orthophotos and with thematic GIS layers generated from the LPIS, biotops of natural and semi-natural grassland and ZB GIS. Generally we conclude that the layer HRL permanent grassland is not well classified. Time series of satel-lite images would help to improve the accuracy of HRLs. In particular, various vegetation phases are a problem when identifying Grasslands. In the future, data HRL Grassland are prerequisites for the use of data and outcomes in a broader context.
