Another little TransDEM update: 2.6.5.1. Download from my website under Download. Or directly: Update Trainz Edition 2.6.* - 2.6.5.1 (English/German, 32bit) Update Trainz Edition 2.6.* - 2.6.5.1 (English/German, 64bit) These are free updates for TransDEM 2.6 users. They require the full TransDEM product being installed, minimum version 2.6.0.0. Please verify that you download the correct variant for your installation, 32 or 64 bit. The update is cumulative again. It will figure out which version is currently installed and patch it to the latest one. There is no change to the manuals by this update. If you already have 2.6.5.0 installed, the update procedure will report the manuals as already being up to date. This latest version of TransDEM has been built against a new set of MS C++ runtime libraries. This set is also bundled with the setup package and should be installed as well. TransDEM-Version 2.6.5.1

A new version of TransDEM has been released: 2.6.6. Download from my website under Download. Or directly: Update Trainz Edition 2.6.* - 2.6.6 (English/German, 64bit) This is a free update for TransDEM 2.6 users. It requires the full TransDEM product being installed, minimum version 2.6.0.0. Please note that this update is 64 bit only. The update is cumulative again. It will figure out which version is currently installed and patch it to the latest one. Once again, this latest version of TransDEM has been built against a new set of MS C++ runtime libraries. This set is also bundled with the setup package and should be installed as well. I am also archiving the 32 bit variant of TransDEM now. Hardly anyone is using it these days anyway. And with the growing availability of hi-res LIDAR-DEMs, memory demands are steadily increasing. The 32bit address space becomes too much of a limitation here. I will keep the 32bit variant and its patches on the server but will no longer update it. TransDEM-Version 2.6.6
No screenshots this time, unfortunately. Korean DEM copyright seems to not allow this. |

Screenshots for DB and other 1m DTM XYZ import, in 1m nominal raster. West of Aschaffenburg main station, north-western Bavaria. Apparently, this is a raw scan, the matrix isn’t fully populated.: After filling up the missing points with the built-in TransDEM function: Surrounded by legacy 50m DEM for Bavaria: And here with the new Bavarian 1m data, which only have become available for free in January this year: Even zoomed in, no seam can be detected. This means that not only the coordinate conversion from DB_REF to UTM is correct but also the elevation base is the same for both data sources: Still not all German federal states have released their 1m data to the general public, so that external sources, like DB here, can still be quite helpful (if you happen to come by such data). To finish the images on xyz import and 1m data another example from the state of Hesse, their hi-res LIDAR DTM also available for free now. Example for GeoTIFF DEMNAS, Indonesia Source: DEMNAS (Registartion required and you might need an online translation tool). I was pointed to this data source by a TransDEM user: viewtopic.php?p=3430#p3430 The sound between Java and Bali, with a volcano adding to the picture. Nominal raster width is 0.27 arc minutes, around 8m, actual resolution seem lower though: Overlay with OpenTopoMap – for those Bali holiday makers, who travel in style by train all across Java and take the ferry from here: Example for missing data in GeoTIFF 1m data from Belgium, Monntzen yard and Moresnet viaduct, close to the German border. Missing values are encoded as -9999. TransDEM up to now didn’t recognise this. And it couldn’t be easily fixed by post-processing, because the data is not native UTM but Belgian Lambert, and interpolation during conversion integrated and altered the no data values: Latest TransDEM Version 2.6.6.1. The GDAL_NODATA tag now works: |
