Sonny's LiDAR Digital Terrain Models of Europe

I'll probably do if there are once Opendata Lidar sources of this German province (Sachsen). Right now I'm afraid there's no such data available for free use.

No free data for Sachsen, that's sad, I'm sometimes @ Erzgebirge.

Oh what a difference, I reset the height levels in Locus pro for some tracks and the Höhenmeter up/down (elevation gain ?) values went down e.g. from 9xx to 500 something...

But I cannot say for sure if I really used the old SRTM data or GPS data pulled by my phone. However, what a big difference. It's overall like 30-40% difference.

Is it possible to use the 20/50m models with Locus?

Sonny · December 19, 2017, 17:52:01

i'm afraid not. But the 1" models (.hgt files) are about as precise as the 20m models

Ah ok, the hgt work well :-)

Thx for that!

I spent many hours and weeks to collect and edit the source data for creating a DTM for the whole country of Italy. Most of the Italian regions provide more or less high quality data. For those who don't, I used 1" SRTM data.
Now the project is finished and available here:

@sonny ...you're awesome! We'll use it for LoMaps as your previous datasets. Thank you

There's been a problem in the Northwest of the Italian files. Please download the corrected ones here:

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.

I have created new files of Germany-Saxony, which you can download here:

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.

There's a new DTM, of Northern Ireland which you can download here:
