Error in "cadastre" tutorial when using mapproxy-tiling (failed to open dataset) #6

Closed fnicollet closed 6 years ago

fnicollet commented 6 years ago

Hello,

I am trying the tutorials, but when it comes to:

 mapproxy-tiling --input srtm --lodRange 9,15 --tileRange 137,85:138,86 --referenceFrame melown2015

I get the following error:

vts@BG-test-soft-3D-FN:~/mapproxy/datasets$ mapproxy-tiling --input srtm --lodRange 9,15 --tileRange 137,85:138,86 --referenceFrame melown2015
2017-07-24 15:57:56 I3 [2529(main)]: [mapproxy-tiling] Config:
        input = "srtm"
        dataset = ""
        output = "srtm/tiling.melown2015"
        referenceFrame = melown2015
        lodRange = 9,15
        tileRange = 137,85:138,86
 {main.cpp:configure():253}
2017-07-24 15:57:56 E2 [2529(main)]: gdal error 4: : No such file or directory {geodataset.cpp:GDALErrorHandler():71}
2017-07-24 15:57:56 E2 [2529(main)]: Failed to open dataset "". {geodataset.cpp:open():327}

Input is set but dataset isn't. In the "--help", there no option for passing a dataset or anything (not sure what I would input anyway)

Is this a known issue?

Thanks, Fabien

Hi Fabien,

it looks like some clash of paths that was created by me and my colleague. Basically all SRTM data should be under /var/vts/mapproxy/datasets/srtm/ but now they are not. Let me go through it and fix the paths.

NB: The mapproxy-tiling needs to be run with --input pointing to the directory that contains dem, dem.min and dem.max symlinks and this path also goes to the mapproxy configuration snippet ("dataset" : "srtm").

Thanks for contribution, Ladislav

ok, I thought that the directory structure it created didn't make much sense, thanks for your help!

Hi, so the section Setting up dynamic surfaces has been fixed in https://github.com/Melown/workshop/commit/2ae1b18d2b0fb9035ddbfcc016b357050b8eaf0d .

Tomorrow I'll go through the rest of the tutorial to make it look more BASHy and more suitable for copy-pasting.

awesome, i'll continue my copy-pasting then, i'll open some PR/issues if I notice anything
