    I want to inform the readers of the English Forum, that there’s a thread in the German Forum about the theory und use of these precise LIDAR elevation files:

    https://www.openandromaps.org/oam-forums/topic/neues-genaueres-hoehenmodell-fuer-oesterreich

    These files are right now available for: Austria, South Tyrol, Slovenia, Luxembourgh, Spain, several German provinces. They are already used by OpenAndroMaps to create the contour lines of these countries. You can download them too and use them to create map-shading and elevation readings within Apps like Locus or Orux.

    If you have questions, please post in the linked thread (in English or German). Not in this thread, thank you!
    (For non-German readers you can simply translate the whole thread using Google Translate: translated Thread)

    As far as I know, I’ve now completed the list of European countries where Opendata LIDAR source data is available. If you notice that there are new European countries providing high quality Opendata DTMs in the future, feel free to contact me!

    Finally something regarding myself: During the last 2.5 years I spent many, many Hundreds of hours during my leisure time to search for new Opendata source files. I’ve written hundreds of Mails – mostly in foreign languages ;-) – to contact public authority of the individual countries to help me with finding free and often hidden source data of their country. I had to download giant amounts of source data. I had to search for errors, plug holes within the data, compile, resample it and create files in useful formats. To provide them to you, the community for free.

    It would make me very happy, if you honor this work by supporting me with a Donation. I’ve created a DONATIONLINK via PAYPAL . THANK YOU VERY MUCH, Sonny.

    After lots of hours of work, finally the latest version of DTMs of Spain are ready for Download:
    https://data.opendataportal.at/dataset/dtm-spain

    I therefor used the latest available source-files of Spanish survey Institute. Most improvements are in regions which lack of LIDAR source data in the previous DTMs: Andalusia and the Balearic Islands.
    Now the whole territory of Spain is covered by high quality LIDAR data.

    Good news: After lots of hours research, contact with different institutes across the country, quality checks etc. there’s for the first time a high-quality DTM of the whole United Kingdom

    https://data.opendataportal.at/dataset/dtm-united_kingdom

    For about 75% of England, Wales, Northern Ireland fine LIDAR source data available, Scotland
    unfortunately (beside river valleys and coasts) is not covered as well. For the areas not covered with fine LIDAR-data I used OS DTM-50m which is wider gridded but also based on LIDAR source data and hence especially in wooden areas more accurate than SRTM data.

    Enjoy the new DTMs of the UK!
