Mount Rainier

[aknight0]

It took a few hours of messing with a 5 GB DEM, but Mount Rainier has finally arrived to join last year's Mount Saint Helens     The LiDAR data I used doesn't appear to have any snow, so trying to dump enough snow on the mountain without losing detail has been a challenge.

Great! Detail is terrific indeed.

Absolut stunning detail!
Where did you get the DEM File?


This is all where I got due to my old computer and just 8GB RAM with my older DEM from Mt. Helens

Here is the DEM I used for this render but you will have to either edit the data or conceal the back end of the Volcano to hide the no data spikes. Other then that it's good detail.

Fantastic render ak! Love how that snow rests on Rainer, it looks very realistic and I dig the composition completely.

The coincidence is uncanny as I've been half working on both of these volcanoes. Making Helen's vegetation and surrounding landscape more to the reality 41 years after.. and have been gradually downloading all the Lidar data for a good quality terrain.

Did you have to download multiple files, assemble them in Global Mapper and export as one?

Wonderful snow! The POV in ecellent as is your use of vegetation.

Thanks!  I used the same DEM as pixelpusher for St. Helens.  For Rainier I used the lidar data here:  https://pubs.usgs.gov/ds/549/.  The files came in ESRI GRID format, which I converted to geotiff with GDAL (https://gis.stackexchange.com/questions/54819/gdal-translate-converting-esri-grid-to-geotiff-in-batch).  The main difficulty was getting a version of GDAL on Windows that would handle geotiff files bigger than 2 GB.  After a few failed attempts I ended up running gdal translate through the windows linux subsystem (https://docs.microsoft.com/en-us/windows/wsl/about) which finally worked.  I haven't used Global Mapper before, maybe that would have been easier      . The price of free tools I suppose 

For the thicker snow fields up top, I used some thermal erosion and colored the talus white, which seems to have worked pretty well, though the distribution is a little different than the real mountain.

THX for your links!

Thanks for link to Rainer! Not sure why you would ever want to redo this render as it's superb, but just so you know. Washington State LiDAR portal includes all laser passes in with the packaged downloads. Trouble is just the mountain alone is probably split up into a hundred different downloads and files.

Useful to know, thanks!
