Trouble building/using the EMOD dataset

Hello,

I’m having some trouble building/using the EMOD dataset. I downloaded the 2020 version of the dataset from the website referenced in the docs, and managed to build a single .vrt file and linking it in config.yaml, although gdalbuildvrt doesn’t recognize -co as an option, so I tried to set VRT_SHARED_SOURCE=0 as an environment variable instead (perhaps this is wrong? I’m not that familiar with the gdal toolchain and geospatial data in general, unfortunately). The linking of the dataset in config.yaml seems to work, but when I try to query a location, I get the following error message:

{
  "error": "Dataset has no coordinate reference system. Check the file 'data/emod2020-vrt/emod2020.vrt' is a geo raster. Otherwise you'll have to add the crs manually with a tool like gdaltranslate.", 
  "status": "INVALID_REQUEST"
}

I’ve also tried using the option -oo, but that results in the same error.

Any pointers here would be greatly appreciated.

I’ve updated the documentation, thanks for helping to improve opentopodata!

Seems to have fixed the issue (at least I get an elevation for a given query point)! I ran the command you wrote above, but for me at least, I had to remove the = in -a_srs=epsg:4326 and replace it with a space. I also used the 2020 dataset.
