TransDEM Forum

Please ignore previous comment about 3d LIDAR tiles. I didn't appreciate that the generation of the tiles involved 2 passes and that the trainz importer , on the second pass, takes hours to generate the complete tile.

Hi,
the LIDAR dem files are presenting problems when trying to create 3D UTM tiles. The first tile is OK but the following tiles are without the IM files and runs for hours.
The LIDAR files have points every 2m
The 2D tiles are ok

More than happy to beta test the new tile size if you a going to support it

The web page is https://environment.data.gov.uk/DefraDataDownload/?Mode=survey
I searched for Oswestry,shropshire
using the pencil tool on the right I drew a ring around Oswestry and pressed the download arrow button
kept the default setting of LIDAR composite DTM, 2022, 2M to save space, and ...

As well as looking at raster maps downloads I have been looking at downloading LIDAR dem maps. They use a tif file format that Transdem does not understand. I can convert the tif files to asc files which Transdem does understand but it would be nice to be able to inport the tif files directly ...

I need some more help, the nls tile server has changed again.
I now need Transdem to contact the nls server using degrees format rather than indexes
Example command

where #14 in the zoom factor
55.76255 is ...

Revisiting an old problem. I did manage to get tiles downloaded from http://nls-0.tileserver.com prefix="os_6_inch_gb/" but on revisiting the tile server it appears to have gone.
I can manually get the tiles from maps.nls.uk using //maps.nls.uk/geo/explore/#zoom=15&lat=51.9689&lon=-1.1034&layers=6&b ...

Thank,
end of the year is fine

Version 2.6 sounds great, when will it be available

Thanks for the input. Rather than manually geo-referencing each downloaded image, I want to automate it. Can anyone point me to some code that translate lat/lon to WGS84 format. With the translation code I can generate the trf file as I download the images.

Mike
