These organisations helped us to with realizing our dream:
- We want to give big thanks to the Ústav pro hospodářskou úpravu lesů (Czech Forest Management Institute) for providing us their high resolution orthophoto map of whole republic. Without their ortophoto would be the mapping progress much weaker. We also want to thank them for providing us their forest database, which was imported into OSM.
- Thanks also to the Český úřad zeměměřický a katastrální for their cadaster map, which is allowing to make our map in high details.
- Ředitelství silnic a dálnic is providing us their road maps. Thanks for that.
- Thanks to the HELP SERVICE - REMOTE SENSING for providing us their data of primary and secondary roads.
