[MapProxy] limiting image width and height in WMS requests?

[Rahkonen Jukka]

Hi,

Oh no, ever more hassle with the Web Mercator codes. It looks like OpenLayes is the one which started to support EPSG:102100 and EPSG:102113, but they are not EPSG codes but ESRI ones. The link on OpenLayers page http://dev.openlayers.org/docs/files/OpenLayers/Layer/SphericalMercator-js.html refers to discussion at http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2009/11/20/ArcGIS-Online-moving-to-Google-_2F00_-Bing-tiling-scheme_3A00_-What-does-this-mean-for-you_3F00_.aspx#12084
and the latter definitely says they are not EPSG codes but ESRI WKID 102113, and ESRI WKID 102100. I would courage anybody to avoid using EPSG:102100 and EPSG:102113.
