Jose: Shouldn't be too hard to add support for that projection. Could 
you file a feature request at

Jeff, I just thought to mention this: function name "wmsmap" maybe
should be changed to "restmap" as for WMS servers will need to do
another template. Here is example urllib call for sample WMS function
GetMap:

========================================
basemap_url = "\

Thanks will do that right now.

I was just investigating possibility of returning clear map without
annotations where it is possible.
For example World_Topo_Map
(http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer)
has additional layers and according layers parameter in export
function (http://atlas.resources.ca.gov/arcgis/SDK/REST/export.html):
========================================
Description: Determines which layers appear on the exported map. There
are four ways to specify which layers are shown:

    show: Only the layers specified in this list will be exported.
    hide: All layers except those specified in this list will be exported.
    include: In addition to the layers exported by default, the layers
specified in this list will be exported.
    exclude: The layers exported by default excluding those specified
in this list will be exported.


Syntax: [show | hide | include | exclude]:layerId1,layerId2
where layerId1, layerId2are the layer ids returned by the map service resource

Example: layers=show:2,4,7
========================================

if we add additional parameter "&layers=hide:5,6,7,8,9" I expected
annotations to be gone, but unfortunately not there yet

Will look further if it's somehow possible to clear annotations.

Regarding your windows error - you have to rebuild basemap to get the 
needed updates (it's not just a matter of running the testwms.py script).

Jeff it looks great, everything is parametrized including server name
and map name, so it should work for any additional service.
However on Windows with Python 2.7 and Basemap 1.0.5 I get an error
while trying to run the script:
========================================
Traceback (most recent call last):

I than added initial empty "epsg" arg to original Basemap class
declaration, but then after some time processing I get:
========================================

So I leave it for now and assume it's some tiny issue not obvious at
this time to me.

I'll continue WMS search, but yesterday I spent couple of hours just
to look at those beautiful maps provided on arcgis server. I explored
on all and it's so nicely done and with high resolution zoom. They are
annotated though, but again, see i.e. Ocean Basemap, or overlay with
transparency over some more colored topo map like GEBCO_08 from
maps.ngdc.noaa.gov server - just great. World Topo also...

Hi,
I'd like to plot some EASE Grid global data (the EASE grid is defined for a
cylindrical equal area projection). In proj4 parlance, it is defined as

+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m
+no_defs

My data are gridded, and I want to use either pcolormesh or imshow to plot
them on a map. Apart from reprojecting into something that basemap deals
with natively, is there something else that I can do within
python/matplolib to plot the data without reprojecting it?

Thanks!
Jose

Hello,
I am not able to get nicer spaces between the xticks with the following
code:

*import random
import matplotlib.pyplot as plt

coverages = [random.randint(1,10)*2] * 100
contig_names = ['AAB0008r'] * len(coverages)
fig = plt.figure()
fig.clf()
ax = fig.add_subplot(111)

ax.yaxis.grid(True, linestyle='-', which='major', color='grey',
      alpha=0.5)

ind = range(len(coverages))
rects = ax.bar(ind, coverages, width=0.2, align='center', color='thistle')
ax.set_xticks(ind)
ax.set_xticklabels(contig_names)
#function to auto-rotate the x axis labels
fig.autofmt_xdate()

plt.show() *

How to get more space between the xticks so they do not look like
overlapped anymore?

Thank you in advance.

Klo:  Yes.  And vice versa, some of those 4500 projections aren't 
supported by Basemap.

Anyway, I went ahead and created a prototype 'wmsmap' method. You can 
try it by cloning my fork (https://github.com/jswhit/basemap) and 
running examples/testwms.py.  I created an extra kward 'epsg' for 
creating Basemap instances. To use the wmsmap function, you have to use 
that keyword.  Give it a try and let me know what you think.

We have a WMS server that uses basemap to display unstructured ocean model data. We just limit the set of projections to a select few (just the most common ones), and have a mapping between EPSG and the required Basemap kwargs. It sometimes requires some implementation of proj4 prior to getting to the Basemap part of the code. I can see that it could be useful and not to difficult to add an EPSG kwarg for a few most common projections and how they would be used by Basemap users.

Klo:  WMS servers use EPSG codes to define map projections - Basemap
uses a set of kwargs.  We need some way of inferring epsg codes from the
Basemap kwargs.  Alternatively, we could extend Basemap so it can accept
EPSG codes.  But, there are many EPSG codes that don't correspond to
allowable Basemap projections, and valid Basemap projections that don't
correspond to EPSG codes.  It's not obvious to me how to proceed.

Maybe it's better not have the function accept a OWSLib wms object -
that way we don't have to tie ourselves to a particular WMS server.

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

The default 'markeredgecolor' (or 'mec') is black, and with small dots, 
you will see more edge color than face color.  To test this, create the 
same plot but with an exaggerated marker size, e.g. markersize=30.  If 
that is the problem, you can fix it by also setting the edge color to 
green, e.g. mec='g'.

[Sending to the list this time--forgot to "reply to all" the first time.]


Success.  I've made the markers larger. The correct color is being plotted. As Warren suggested, without specifying markeredgecolor I see mostly black border with the smaller marker size. Thanks to all for the help.

Dear matplotlibers,

I encountered a bug (?) in fill_between when using logarithmic scales and
the last part of y and yerr arrays as set to zero: a diagonal stripe going from
the rightmost non zero value to the first value is drawn.
It's visible in the right panel of the attached figure, while is not
present if the plot is linear (left panel).
If xaxis is log and yaxis is linear the plot is correctly drawn.

I'm using mpl.__version__ = '1.1.1rc' under Kubuntu 12.04 with Python 2.7.3

The plot has been created with the script below.

Is this a bug or am I missing something?

Cheers
Francesco


##### error_fill_between.py ######
import matplotlib.pyplot as plt
import numpy as np

#values to plot
x = np.linspace( 1, 10, num=100 )
y = np.exp( -x**2 )
y[50:] = 0
yerr = y* np.random.rand(100)

#figure
fig = plt.figure()

ax1 = fig.add_subplot(121)  #first axes: linear
ax1.errorbar( x,y,yerr, c='r' )
ax1.fill_between( x,y-yerr,y+yerr, color='b', alpha=0.4 )

ax2 = fig.add_subplot(122)  #second axes: logarithmic
ax2.errorbar( x,y,yerr, c='r' )
ax2.fill_between( x,y-yerr,y+yerr, color='b', alpha=0.4 )
ax2.set_xscale( "log" )
ax2.set_yscale( "log" )

plt.show()
###### end script  #########

Klo:  WMS servers use EPSG codes to define map projections - Basemap 
uses a set of kwargs.  We need some way of inferring epsg codes from the 
Basemap kwargs.  Alternatively, we could extend Basemap so it can accept 
EPSG codes.  But, there are many EPSG codes that don't correspond to 
allowable Basemap projections, and valid Basemap projections that don't 
correspond to EPSG codes.  It's not obvious to me how to proceed.

Maybe it's better not have the function accept a OWSLib wms object - 
that way we don't have to tie ourselves to a particular WMS server.

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.

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.

Thanks,
Tim

Hi,

I'm having trouble installing matplotlib on my Mac OS X mountain lion
(10.8).

See my output below.  Note two things:

1.  The error is "predicted" by

             freetype2: found, but unknown version (no pkg-config)
                        * WARNING: Could not find 'freetype2' headers in any
                        * of '/usr/local/include', '/usr/include',
                        * '/usr/X11/include', '/usr/local/include',
                        * '/usr/include', '.',
                        * '/usr/local/include/freetype2',
                        * '/usr/include/freetype2',
                        * '/usr/X11/include/freetype2',
                        * '/usr/local/include/freetype2',
                        * '/usr/include/freetype2', './freetype2'.

even though I have pkg-config installed via "brew install pkg-config"

2.  For some reason, the installer cannot find "ft2build.h".  To the best
of my knowledge, this file is not on my machine:
In file included from src/ft2font.cpp:3:

src/ft2font.h:16:10: fatal error: 'ft2build.h' file not found

#include <ft2build.h>

         ^

1 error generated.

I have installed pkg-config via "brew install pkg-config", and "brew
doctor" gives me no issues.  I installed matplotlib via the command:

sudo pip install git+
https://github.com/matplotlib/matplotlib.git#egg=matplotlib-dev

Does anyone know what might be the issue here? I had no problems on OS X
10.7...

Thanks,
Tim

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).

Indeed I was running Apple Python instead of macport.

Thanks for all that pointed it out.

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.

BTW I checked one WMS server
(http://wms.jpl.nasa.gov/wms.cgi?request=GetCapabilities). It has
tiling service (GetTileService) and mapping service (GetMap) but only
in standard projection EPSG:4326

Here are maps provided:
 1 - WMS Global Mosaic, pan sharpened
 2 - WMS Global Mosaic, not pan sharpened
 3 - CONUS mosaic of 1990 MRLC dataset
 4 - SRTM reflectance magnitude, 30m
 5 - Current global view of the earth, morning
 6 - Current global view of the earth in the afternoon
 7 - Blue Marble Next Generation, Global MODIS derived image
 8 - Blue Marble, Global MODIS derived image
 9 - SRTM derived global elevation, 3 arc-second, hue mapped
10 - Global 1km elevation, seamless SRTM land elevation and ocean depth
11 - SRTM derived global elevation, 3 arc-second
12 - United States elevation, 30m
13 - Digital Elevation Map of the United States, DTED dataset, 3
second resolution, grayscale
14 - Digital Elevation Map of the United States, DTED dataset, 3
second resolution, hue mapped
15 - ASTER DEM, tiled only, 1.5 arc-second per pixel

Only first two offer international locations (from Landsat)

All right, that's the right way anyway

Yes, and also to pass right `size` parameter as aspect ratio needs to be correct
Do you want me to try to pair both projections (Basemap name and WKID
and WKT as they call it)?

Looks beautifully :)

As said later today I'll look at Nokia maps and then will try to look
for WMS servers.

Klo:  The image in interpolated to the Basemap projection region. This 
is slow - the main reason to use the WMS is to avoid this by having it 
done on the server side.

The trick is to figure out what the EPSG projection code is based on the 
Basemap projection info, and pass that information to the WMS server so 
it can do the interpolation.

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()

Well it seems ArcGIS web-services can't be bitten in public place.

Google and Bing static maps have many limitations:
 - require account for providing key
 - draw logos on image
 - limited size: Bing basic account can return max 900x834 and Google
1280x1280 (while ArcGIS 2048x2048)
 - Google static maps has max 25K requests per day per application and
not per IP
 - Bing static map doesn't return requested exact coordinates, and I
can't see parameter that can define returned image SR (haven't checked
Google)

I'll have a look tomorrow at Nokia (img size limit 2048x2048), but
considering OWSLib and providing arcgis webservice function to Basemap
class seems fine.
Also just reusing some of OWSLib solution for map services doesn't
seem like bad idea - nothing is required except Python builtin XML
parsing

Success! :)
It was that "imageSR" had to be set, as it doesn't seem to be deduced
from the map:

========================================
basemap_url = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Physical_Map/MapServer/export?\
bbox=%d,%d,%d,%d&\
bboxSR=4326&\
imageSR=4326&\
size=800,600&\
dpi=128&\
format=png32&\
f=image" % (lon1, lat1, lon2, lat2) \
========================================

Result with coastlines overlay attached!

Jeff, I think it is easy to make this function to Basemap class, but
I'm not confident doing it.
If you can make it, I'll then try to use it as template and pair it to
other available webservices

Cheers
