Thanks for explaining Jeff, but aren't we using arcgis REST service which accepts more then 4500 projections? Are you saying Basemap offers projection that's not listed here: http://atlas.resources.ca.gov/arcgis/SDK/REST/gcs.html EPSG codes may be important to WMS. And providing WMS feature is maybe question how. Any GIS tool has WMS service support. Some WMS servers provide tiling capabilities and that also can be considered for future feature of fast zooming in Basemap. Most of them seem to offer just EPSG:4326 and there are servers with many projections (not as many as arcgis REST service) But at this point of static map servers we can just use urllib module and do requested WMS function which will return the map without using any additional function or package I'm validating public WMS servers and these days I'll report again. As mentioned many simply aren't working, many are localized, etc. Hope will find nice usage for some selected ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
