topic Is it possible to use python to load a WMS from the Environment Agency? in Developers Questions https://community.esri.com/t5/developers-questions/is-it-possible-to-use-python-to-load-a-wms-from/m-p/47527#M256 <HTML><HEAD></HEAD><BODY><P>I am carrying out analysis on a variety of datasets which are in GeoDatabases and projected to British National Grid. One of the datasets required is provided as a WMS feed (Open Data from Environment Agency) and its coordinate system is GCS WGS84. As their will be numerous maps to be generated using different locations, I have automated the analysis (distance to features) and map production using Python. There are offset issues between the WMS feed and the OS StreetView background mapping I am using when I use automation to load a lyr file (of the WMS feed). I have tried various settings in the map templates but the WMS feed is always offset unless I manually open the mxd and manually load (using AddData) the WMS feed. My need for help is:</P><P></P><P>Can I change the coordinate system of the WMS feed without contacting the supplier?</P><P>Why, if I load the WMS feed and it is positioned correctly then save the mxd does the offset re-appear when I use python to add other datasets?</P><P></P><P>I have attached two images showing the issue. The _correct one I added the WMS feed manually, the _offset is when the mxd was manipulated by Python</P><P></P><P>cheers in advance</P></BODY></HTML> Wed, 07 Sep 2016 15:24:16 GMT DarrenConnaghan1 2016-09-07T15:24:16Z Is it possible to use python to load a WMS from the Environment Agency? https://community.esri.com/t5/developers-questions/is-it-possible-to-use-python-to-load-a-wms-from/m-p/47527#M256 <HTML><HEAD></HEAD><BODY><P>I am carrying out analysis on a variety of datasets which are in GeoDatabases and projected to British National Grid.
