tif is not included in GeoTiff format

[sdobz]

I prefer to do my own generation of geometry so I have previously used the geotif export feature.

Initially I was using a jupyter notebook packaged using nix BTW: this was a LOT of work, but ooo boy it'll work for a long time.

After setting

args["fileformat"] = "GeoTiff"

I got a zip file, but it was mostly empty.

The webapp has the same issue: this url previously included a tif, now it is a zip with just the logfile.

The source code offers a clue

TouchTerrain_for_CAGEO/touchterrain/common/TouchTerrainEarthEngine.py

Line 1874 in 082548b

if importedDEM == None and fileformat != "GeoTiff":

This line was changed 2 months ago:
3af0e0b

Unsure what the intent is there, but this probably isn't what you want!

I'd love to be able to compose parts of the code together, specifically I am analyzing the heightmap to center a circle on the peak and determine the minimum elevation in a ring around the center point.
Three options:

1. Run touchterrain to get a tif, analyze update and generate a dem, then run it again on the importedDEM
2. Ruthlessly copy paste bits of code out of this project and into my own
3. Refactor TouchTerrainEarthEngine to have composable elements

For now I'm probably going to fix this bug in a fork and go with 1, thanks for this excellent project! I love the mission of tactile terrain and have been investing considerable time into it.

Here's some projects, pardon the irrelevancy I'm just stoked to share 😁

Vincent, I'm aware of geotiff export not getting a plot/histgram file. the "fix" a while ago was needed to make geotiff export working again but I'm happy to look at it again. Cheers Chris

Very nice, never would have though of that :)

Vincent, I think I fixed it but I would like you to test it first on beta before I push it to prod. Can you give https://touchterrain-beta.geol.iastate.edu/ a bit of a workout?

[sdobz]

I was able to get a tif out of my previous url, but my attempts to get a stl are failing with timeout

[ChHarding]

I think your job is just too big for our server if somebody else is using it. I just run it and it's a 800 Mb file. How about you lower the printres to 0.4? Or are you actually printing with a 0.199 mm nozzle? Also the beta server has only 2 Gb of memory so it's more likely to run out of it. I'm about to put the changes on prod (touchterrain.geol.iastate.edu) which has 4 Gb, so it should work better there.

[ChHarding]

It's now deployed on https://touchterrain.geol.iastate.edu/
