I trying to set up the CRS scales/resolution for a map accordingly to the provided information of an WMTS getCapabilities request. At the moment I'm playing with the following service.

The service provides me with the following TileMatrix information:

  <TopLeftCorner>200000.0 6075000.0</TopLeftCorner>

Based on an OpenLayers example from this source the resolutions should be:


I've created a fiddle that uses the resolutions specified in the example. Using these informations the map displays as expected. But how do I calculate the resolution based on the provided ScaleDenominator?


1 Answer 1


I've managed to calculate the resolutions using the following equation:

resolution = ScaleDenominator * PixelWidth

529.166666667 = 1889880.95238 * 0.00028
