Hi all, I skipped the orthophoto stage, as I only wanted a DEM, but when I go to the map viewer is says “Bounds are not valid”. It doesn’t really matter as I’ll view it in QGIS anyway (as I need to convert it to British National Grid - something else that doesn’t work in ODM - exporting in EPSG:27700). But thought I’d bring it up as an issue that might be easy to rectify?? Thanks 🙂

Yeah, we don’t have a means to estimate a footprint or display anything in the 2D view when there are no 2D products to view.
What would you expect to see in this case?
Can you help us with a PR to fix it?

Cheers for the reply, I would expect that when I click to view map the DEM would appear in the viewer just like the orthophoto appears, and the DEM appears when there is also an orthophoto. Isn’t the DEM a 2D product like the orthophoto?

Yep!
It looks like we might need better logic for the 2D Viewer.
It’s this something that you can help us with?

Probably a bug, a PR to help fix this would be most welcome.
