// following works without gdalwarp:
$ wget https://ns_hwh.fundaments.nl/hwh-ahn/AHN3/DTM_5m/M5_65HZ2.zip
$ unzip M5_65HZ2.zip
$ gdalbuildvrt ahn.vrt M5_65HZ2.TIF 
$ mkdir tiles
$ docker run -it -v D:/aaa/testdownload:/data tumgis/ctb-quantized-mesh ctb-tile -f Mesh -C -N -o tiles ahn.vrt

// following does not work with gdalwarp:
$ wget https://ns_hwh.fundaments.nl/hwh-ahn/AHN3/DTM_5m/M5_65HZ2.zip
$ unzip M5_65HZ2.zip
$ gdalwarp -s_srs EPSG:7415 -t_srs EPSG:4326+4979 M5_65HZ2.TIF M5_65HZ2_4326.TIF
$ gdalbuildvrt ahn.vrt M5_65HZ2_4326.TIF 
$ mkdir tiles
$ docker run -it -v D:/aaa/testdownload:/data tumgis/ctb-quantized-mesh ctb-tile -f Mesh -C -N -o tiles ahn.vrt

Error: The source dataset does not have a spatial reference system assignedError: The source dataset does not have a spatial reference system assigned

But following works (without VRT):

$ docker run -it -v D:/aaa/testdownload:/data tumgis/ctb-quantized-mesh ctb-tile -f Mesh -C -N -o tiles M5_65HZ2_4326.TIF

Fix: set the srs somewhere? how?

Attempts:

- $ gdal_edit -a_srs EPSG:4326+4979 ahn.vrt -> same error
- $ gdal_translate -a_srs EPSG:4326+4979 ahn.vrt ahn1.vrt -> same error
- $ gdalbuildvrt ahn.vrt -a_srs EPSG:4326+4979 M5_65HZ2_4326.TIF -> same error

Fix?

- $ gdalbuildvrt ahn.vrt -a_srs EPSG:4326 M5_65HZ2_4326.TIF
