So, since this topic is very important for my project, I just wanted get to know more about this new EU law about the provision of digital geography data and its influence on the german states to provide their LiDAR for free in 2024. So, I found this article here by the "Bundesamt für Kartographie und Geodäsie" (Federal office for cartography and geodesy"): https://gdz.bkg.bund.de/index.php/default/hinweise-adv-gr-4/ It says that the fees policy of the AdV ("Arbeitsgemeinschaft der Vermessungsverwaltungen der Länder der Bundesrepublik Deutschland") will change to its 4.0 form, presumably come into effect at/from 9th of June 2024. In this document it says that the ZSGT ("Zentrale Stelle für Geotopographie" - 'central office of geotopography) will provide the DGM ("Digitales Geländemodell") for all states in its OpenData source then: Also important to note, that the DGM will probably be provided in grid width of 1m (or if dreams come true even 50cm), because it says that the ZSGT will provide from then the highest quality only and the grid widths of 5m, 10m, 25m and 50m will not be available anymore/provided. So, this seems to be very good news for all our projects in Germany, which are not covered by high quality 1m resolution DGM, yet. I hope this will come true and the Lidar data will be available as soon as possible for us all to work with and provide better landscapes for our routes. Fingers crossed!
That would be amazing! I always planned on creating a bavarian route, since that area interests me the most, however currently bavarian data costs( sadly the price would not be worth for some testing tiles).Now we just need Bing Maps or OpenStreet(or -Railway-)Map support, but maybe I have an Idea. Will try it out when I'm home.
I know that the LIDAR data for NRW has been freely available for some time. Is there a list of all the federal states that already do this?
I think all states except Ba-Wü provide LiDAR data for free, although not always the 1mx1m tiles. This is definitely good news concerning the quality also.
I can say you a few which I know of which do, and which don't. States where Lidar is available for free yet: - Hessen - (DGM1) - Thüringen - (DGM2) - Nordrhein-Westphalen - (DGM1) - Sachsen (Saxony) - (DGM1) - Sachsen-Anhalt (DGM2) - Bayern (Bavaria) (DGM1) - Schleswig-Holstein (DGM1) - Brandenburg (DGM1) *Be aware that it doesn't necessarily need to be actual Lidar data which is offered here. States where it isn't free yet: - Rheinland-Pfalz (DGM25, but almost no difference to SRTM with 30m width) - Mecklenburg-Vorpommern - Niedersachsen - Baden-Württemberg
As far as i know Bavarian Lidar data is free. I built my Schnellfahrstrecke Nürnberg Ingolstadt with full Lidar Data.
DGM1 seems to be available for bavaria free yet: https://geodaten.bayern.de/opengeodata/OpenDataDetail.html?pn=dgm1 (also I think DTG would not made so many routes in Bavaria if it weren't)
Really? This whole time I coudn't find it! Thanks. Btw does anyone know how to enable plugins? Does not work for me( sadly)
So because of the problem that finding Lidar can be difficult, I decided to share all links to the current free Lidar repositories here where you can download the Lidar tiles. I guess it can be helpful for all of those who want to start their project before June this year (maybe even longer - who knows). Generally, you can find all Lidar in Germany by searching in your webbrowser for "Digitales Geländemodell" (Digital Terrain Modell) + the state you're looking for. It's often not so easy to find and you need to search through a few webpages to get to it but for most cases it isn't rocket science (while actually downloading it might be , but you have to found out how this is done for each state on your own). Important note: 1.)There might be more DGM data records available. These are just the ones that I did found after a few minutes research. Also there might be data records for states not listed here available such as Berlin. I actually found a data record with a table of DGM1 data available but there is no selection for a map provided and getting these data together to the ones you need, might take some time. 2.) It's likely that the links below will not work any longer up from June this year, because as said in the OP, the Lidar data seem to be distributed for a country-wide portal then. Anyway, I hope this quick table can help you out if you're looking for a Lidar source.

Where can you find lidar data for Thuringia? Currently you can only get data in 1x1 km via the link? This isn't exactly a good thing, is it?
It could be that I misunderstood something. I just thought, since you can currently only find lidar data with 1x1 km resolution (1000mx1000m) for Thuringia, that this wouldn't be particularly good. I once read that SRTM already has a resolution of 30m. So I thought that lidar data with a resolution of 1km wasn't very good. But if I'm misunderstanding this, please enlighten me as I'm not entirely sure.
I believe 1 km x 1 km is the size of the tiles you can download, not the resolution of the data within them.
Thank you. Now I'm smarter: Thuringia provides 3 different types, the details can be seen if you look a little closer. Further down the page there is a “Data Description” section. Then you have to read carefully in the document that opens. In the middle it says: "Height data from 2010-2013 in 2m grid width, 2014-2019 in 1m grid width and 2020-2025 under construction" This information was really a bit hidden, but now I understand it. The 1x1 km referred to the tile size (thanks for the tip). Depending on the year, the data then has a resolution of 1 or 2m grid width.
Wasn't online for a while. And since a few people asked me on Discord, yes Lidar is free for all german states now. I didn't supervised how every state handled it especially but with an eye on the Lidar data in Rheinland-Pfalz, the government provided for free already on June 5th. 4 days before the law took action officially. Here is a list of the now free Lidar sources which become OpenData from the states Baden-Württemberg, Mecklenburg-Vorpommern, Niedersachsen and Rheinland-Pfalz (in this - alphabetical - order). I also provided the EPSG codes which you need for conversion with a special mention to Mecklenburg-Vorpommern. Baden-Württemberg (DGM1 and DGM025): Special mention here. Baden-Württemberg made a big surprise here. From no free Lidar at all before, it not only offers DGM1 (grid width of 1 meter) but also DGM025 (grid width of 25 centimeter) now. This should be the highest resolution offered for free in comparison to all other german states but also entire countries. Although it probably would be recommended to download the Lidar data of the higher resolution of 25 centimeters, keep in mind that higher resolution also means bigger files, more data and more data to deal with at the conversion processes in QGIS. You also need the respective storage capacity (hard drive wise) to store these datas. I personally already had problems with that for a larger railway section in DGM1 format. To be honest, I'm unsure if it there even is a big difference between 1 meter and 0.25 meter resolution for our railway projects. But I'll let it open to you to decide which one to take. DGM025: https://opengeodata.lgl-bw.de/#/(sidenav:product/4) DGM1: https://opengeodata.lgl-bw.de/#/(sidenav:product/3) EPSG code: 25832 Mecklenburg-Vorpommern (DGM1): https://laiv.geodaten-mv.de/afgvk/Geotopographie/Download?produkt=DGM1 Important info regarding the EPSG code. On the main page it suggesst that the code would be 25833 for all Lidar. It's true that MV is mostly on territory of the 25833 code. However, the border between area of 25832 and 25833 runs through Mecklenburg-Vorpommern so it could be that for some parts in the very west of the state of MV, it could have an EPSG code of 25832 instead of 25833. But this is just my theory and not officialy confirmed. Just in case you got any problems in conversions, maybe try EPSG 25832 for Lidar tiles in the west of Mecklenburg-Vorpommern. Niedersachsen (DGM1): https://ni-lgln-opengeodata.hub.arcgis.com/apps/lgln-opengeodata::digitales-geländemodell-dgm1/explore EPSG code: 25832 Rheinland-Pfalz (DGM1): https://geoshop.rlp.de/opendata-dgm1.html https://geoshop.rlp.de/digitale_gelaendemodelle/digitale_gelaendemodelle_dgm.html (Both pages should give you the Lidar in an equal way) Especially for Rheinland-Pfalz, the selection method is a bit weird in comparison to other states. One can select only 10 tiles at a time, then pack it in a bundle. After you laid this bundle into your cart you can repeat the process for the next 10 tiles and so on for your project. You also need an email adress, where the government will send you the links to. It's not that easy, but if you invest a bit of time and will to investigate how it works, you'll get it done. EPSG code: 25832
I found it amazing that all of the remaining states actually managed to be on time with this. There was much speculation how long it would really take for them to release it for free. Good to see they opened it up. I hope it will help many projects (freeware but also payware) to carry on and get released, eventually…
