[gdal-dev] WMTS services error

Fri Feb 12 05:05:03 PST 2021

Hello, my goal is to obtain images of both WMS and WMTS web services using GDAL, with the CRS that each service provides, in the case of the example, how can I do then to obtain images in EPSG: 4326 or any other CRS that have changed axes? Should a parameter be added to the gdal_translate call? What would be the correct way to obtain this type of images using gdal applications like gadlinfo and gdaltranslate?
I have found very little information about this on the web, many thanks and best regards

Elena,

I'm not exactly sure what is causing the issue but if you look at the capabilities of the 4326 tilematrixset compared to the InspireCRS84Quad the topleftcorner coordinates are reversed.  My guess gdal is expecting a X Y order.

<TileMatrixSet>
<ows:Identifier>InspireCRS84Quad</ows:Identifier>
<ows:SupportedCRS>http://www.opengis.net/def/crs/OGC/1.3/CRS84</ows:SupportedCRS>
<TileMatrix>
<ows:Identifier>0</ows:Identifier>
<ScaleDenominator>2.79541132014358E8</ScaleDenominator>
<TopLeftCorner>-180.0 90.0</TopLeftCorner>
<TileWidth>256</TileWidth>
<TileHeight>256</TileHeight>
<MatrixWidth>2</MatrixWidth>
<MatrixHeight>1</MatrixHeight>
</TileMatrix>

<TileMatrixSet>
<ows:Identifier>EPSG:4326</ows:Identifier>
<ows:SupportedCRS>EPSG:4326</ows:SupportedCRS>
<!--  crs="urn:ogc:def:crs:EPSG::4326"  -->
<TileMatrix>
<ows:Identifier>EPSG:4326:0</ows:Identifier>
<ScaleDenominator>2.795411320143589E8</ScaleDenominator>
<TopLeftCorner>90.0 -180.0</TopLeftCorner>
<TileWidth>256</TileWidth>
<TileHeight>256</TileHeight>
<MatrixWidth>2</MatrixWidth>
<MatrixHeight>1</MatrixHeight>
</TileMatrix>

Hello, I´m trying call web services (WMTS and WMS) using GDAL 3.0.2, but I have a problem with this example:

Input file size is 20616192, 26817505

In this server http://www.ign.es/wmts/pnoa-ma have available the next SRS :
SUBDATASET_1_NAME=WMTS:http://www.ign.es/wmts/pnoa-ma?request=GetCapabilities&service=WMTS,layer=OI.OrthoimageCoverage,tilematrixset=InspireCRS84Quad
SUBDATASET_2_NAME=WMTS:http://www.ign.es/wmts/pnoa-ma?request=GetCapabilities&service=WMTS,layer=OI.OrthoimageCoverage,tilematrixset=EPSG:4326

SUBDATASET_5_NAME=WMTS:http://www.ign.es/wmts/pnoa-ma?request=GetCapabilities&service=WMTS,layer=OI.OrthoimageCoverage,tilematrixset=GoogleMapsCompatible

But when I want Know the information or download a image in certain coordinates  with EPSG:4326, it returns an error “ERROR 1: Invalid dataset dimensions : -135056383 x -167901439”, with EPSG:25830 works fine. I don`t understand this error, someone could help me?

Thank you and regards
