Problems with loading OpenAerialMap WMTS

[simboss]

I am unable to load WMTS layers from OpenAerialMap, I am not sure this depends on MapStore 2 or not.

It is worth doing an investigation as some time. Here is an example but data mightnot be there anymore when we investigate: in such case just go to OpenAerialMap and load one of the samples.

After a quick investigation I found that this issue could be caused by:

• wrong parsing of tilematrix set from catalog utils (when is only one isn't parsed as array)
• missmatch between ows:Identifier and tile matrix set
• unhandled url template ...url.../{TileMatrix}/{TileCol}/{TileRow}@2x.png

@simboss The issues described in the previous comment are solved on the current master of MapStore but the layers from OpenAerialMap are not visible yet. They are not visible yet because wmts capabilities provide a TileMatrixSet with size 512px x 512px and MapStore supports only 256px x 256px for WMTS layers.

After some quick tests on the mapping libraries of MapStore I was able to display a layer only in openlayer by switching the 256 tileSize to 512 (hard-coded) but this test didn't work with leaflet and cesium.

We need to introduce support for tile sizes different from 256px x 256px in all the mapping libraries of MapStore.

@allyoucanmap can you make an estimate for this?
