mapzen: make run error #82

Hi There,

I changed the dataset from the test one to mapzen.

I extracted all the files and now I have the following data: data/mapzen/ N00 N01 ... each folder has N00E000.tif N00E024.tif and so on When I run make run then I get an error: ERROR:root:Invalid config: SRTM-type tile coords must be unique, cannot be the same tile with different extensions. ERROR:root:Uncaught exception while trying to pre-populate the cache. This probably means that Open Topo Data isn't working.

Which format should be the mapzen files at the end?

Sorry for the delay in getting back to you!

The filename N00E024.tif is fine!

What sometimes happens is temporary/other files get created like N00E024.pdf or N00E024.tmp. This can be due to transfer errors for example.

Now when opentopodata needs to look up the file N00E024 it doesn't know whether to read N00E024.tif or N00E024.pdf.

The challenge is finding this unnecessary file, and I admit opentopodata isn't very helpful here.

You could use a command like

cd data/mapzen/
find . -not -name "*.tif"

Let me know if this helps, and if so, what file extension caused the issue. Because this is a common issue, I have a list of extensions that opentopodata will ignore (for example .tmp).
