There was a problem hiding this comment.
This function should be perhaps named as "restmap" or "arcgismap" as it should be able to process any valid ArcGIS Mapserver with REST protocol. For WMS servers we'll need to do another template and maybe call it wmsmap or wmsimage. Here is example urllib call for sample WMS function GetMap:
basemap_url = "\
http://geonetwork3.fao.org/ows/14097?\
request=GetMap&\
service=WMS&\
version=1.1.1&\
layers=country_bnd&\
format=image/svg%2Bxml&\
bgcolor=0xFFFFFF&\
transparent=TRUE&\
srs=EPSG:4326&\
bbox=-180,-137.464503042596,180,137.464503042596&\

"It's very similar to already implemented, only that some parameters are differently named.
Additionally SRS is acceptable in WMS 1.1.1, and CRS in WMS 1.3.0 which should be deduced from WMS server version. Both default to EPSG:4326

OK, renamed it 'arcgisimage'. |

for retrieving and displaying background images from web map servers. Requires that projection be defined using the new 'epsg' keyword, except for projection='cyl', which is automatically assumed to be epsg=4326. Run testwms.py to exercise this new feature.
