Nokia map services are OK, and can be used even without applying for free account, but they brand every map with their logo even for professional licence. REST services (http://api.maps.nokia.com/en/restmaps/overview.html) are very limited, in one projection and mapped according central point instead bounding box. They offer (http://api.maps.nokia.com/en/index.html) other approaches like JS, JAVA, HTML5 and perhaps some more advanced service can be deduced from there in Python, but it's not worth perhaps.

Klo: Since epsg codes comprise a very small subset of possible Basemap projections, it may be better to just allow Basemap to accept an epsg kwarg. That keyword would be required in order to use a WMS to display a map background. This may be tricky though, since Basemap needs more information to define a map projection region than is provided by the epsg code. We may have to start with just a few supported epsg codes and then add more as necessary. I added a testwms.py example to my fork (https://github.com/jswhit/basemap.git) that shows how to use three different map projections (epsg codes). -Jeff -Jeff > > >> Here's an example for south polar stereographic: >> >> width = 12000.e3 >> plt.figure() >> basemap_url =\ >> "http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_Imagery_World_2D/MapServer/export?\ >> bbox=%d,%d,%d,%d&\ >> bboxSR=3412&\ >> imageSR=3412&\ >> size=800,800&\ >> dpi=128&\ >> format=png32&\ >> f=image" % (-width/2,-width/2,width/2,width/2) >> m =\ >> Basemap(projection='stere',resolution='i',lon_0=0,lat_0=-90,lat_ts=-70,\ >> width=width,height=width,rsphere=(6378273,6356889.449)) >> m.imshow(plt.imread(urllib2.urlopen(basemap_url)),origin='upper') >> m.drawmeridians(np.arange(-180,180,30),labels=[0,0,0,1],color='y') >> m.drawparallels(np.arange(-80,-0,10),labels=[1,0,0,0],color='y') >> m.drawcoastlines() >> plt.show() >> > Looks beautifully :) > > As said later today I'll look at Nokia maps and then will try to look > for WMS servers. -- 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.

[Matplotlib-users] Install error on Mac OS X 10.8 (mountain lion): ft2build.h

Re: [Matplotlib-users] Install error on Mac OS X 10.8 (mountain lion): ft2build.h
Hi, It turns out I was missing two packages: freetype and libpng. These could be downloaded as brew install freetype brew install libpng I thought I had done this... I may have re-installed pkg-config via brew as well. I'm not sure why I was unable to google this After making these changes I had no problem installing the development version of matplotlib.

I'm not sure if I understand projection problem, as arcgis webservice provides thousands of projections, but then you know better. I thought that the code will be just one function which would accept Map name, then coordinates and projection code will be deduced from Basemap function initiation? Here is same server from agency where you work according your signature: maps.ngdc.noaa.gov/rest/services it provides additional maps on same server as arcgis I also checked many WMS servers, first with XML editor but then with Gaia, which was excellent help in determining that many WMS servers just return their capabilities, but does not provide service as described in capabilities response. Some offer tilling features, for possible future interactive zooming in Basemap ;) Here is one http://maps.dwd.de/geoserver/wms?request=GetCapabilities&service=WMS&version=1.1.1 which offers bluemarble in many projection. Additionally it offers some German datasets, but does not offer tilling service. Perhaps we could look just for servers with get map service but also tilling support and support for various projections. -- 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.
