[gdal-dev] GDALCreateWarpedVRT and .msk files

[Even Rouault]

Sean,

I've just tested with GDAL trunk and latest state of 2.2 branch (but I think that 2.2.2 should behave the same), and when using gdal.AutoCreateWarpedVRT() on your below mentionned dataset, the .msk file is read.

$ CPL_CURL_VERBOSE=YES CPL_VSIL_CURL_ALLOWED_EXTENSIONS=tif,msk FILE=/vsicurl/http://oin-hotosm.s3.amazonaws.com/5a324a622553e6000ce5aaf5/0/3fa181a1-425c-4e53-b49f-ea72884da097.tif python
[...]
>>> from osgeo import gdal
>> import os
>>> file = os.getenv('FILE')
>>> src_ds = gdal.Open(file)
[...]
>>> ds = gdal.AutoCreateWarpedVRT(src_ds)
[...]
