There's a new version (v2) of DTM Austria, my oldest DTM. Therefor I downloaded the latest LiDAR source data of Austria's federal states.

Additionally I created 2 models with finer resolutions (10m and 0.5"). These fine gridded models will kept limited to Austria.

By the way: There's one European country left which offers precise 1m-OpenData Lidar source data: Poland.

But it's not possible to download the enourmous data for the whole country due to the limitations in the download methods. I already contacted the Polish office (GUGiK), but they seem not willing to improve their download methods nor offering an alternativem less dense gridded DTM (e.g. 10m) for the whole country which would result in an ideal file size to download.

If somebody of you is interested in a Lidar-DTM of Poland, you could contact them too, to make them understand the request for a countrywide download of their elevtion data.

I created new DTM of the whole of Germany. Not each federal state is offering OpenData elevation data yet. Please open the image “_Sources.png” in the download package to check the type of Sourcedata for each region.

Furthermore I created a new DTM of Slovakia, please check:

I created a new Version of Swiss DTMs, with great improvements in large parts of the country:

They are based on new high-quality OpenData sources of Swisstopo.

By the way: I created a Twitter account to post news and answer questions. If you want me to follow:

I'm not sure if there are Opendata LiDAR sources avalable for these coutries yet. If you know some, please post the links where to get them.

Since some weeks LiDAR source data of the whole territory of France in its finest resolution is available as OpenData. So during the last weeks I created enhanced DTMs of France:

Additionally Wallonia (Souther Belgium) also provides their LiDAR sources in its finest resolution as OpenData. So I created enhanced DTMs for Belgium too, now the whole country is complete in highest resolution:

Have fun, Sonny.

Einstellungen > Foto Einstellungen > Bildqualität

Ich nutze da 86 %, da gibts noch so gut wie keine sichtbaren Bildartefakte.

Könntest du Beispielbilder hochladen, je eins mit Locus+OpenCamera und mit Locus+StadardCameraApp und ev. noch 2 weitere nur mit OpenCamera und StandardCameraApp gemacht (ohne Locus).

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!

Der Höhenunterschied der einzelnen Höhenlinien hängt nur von der verwendeten Karte ab, und nicht von den verwendeten SRTM-Höhendateien in Locus.
Ich bin mir nicht sicher ob es sich um eine OpenAndroMaps handelt, denn auf diesen sind die Höhenlinien normalerweise alle 20m eingezeichnet.

Zusätzlich zu dem was balloni und Henk geschrieben haben sei noch gssagt: Die "Dreiecke" stammen ja aus der OpenStreetMap und bezeichnen einen Gipfel. Dort kann man Gipfelpunkt auch ohne einen Höhenwert und auch ohne Namen eintragen. In diesem Fall würdest du nur ein Dreieck sehen. Höhenwerte und Gipfelnamen zu einem Gipfelpunkt sind in den Kartendaten zwar meistens vorhanden - aber nicht immer.

Die von Henk gezeigte "dynamische Höhe" in roter Schrift basiert dagegen nicht auf OpenStreetMap, sondern auf externen Höhendateien. Diese zeigen für alle Positionen eine Höhe an, also auch für jene Gipfel ohne Höhenwert in OpenStreetMap.

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 the 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.
