locale.setlocale(locale.LC_NUMERIC, 'C')

Unfortunately, it seems to use the old Transforms mechanism, so won't

have you ported it over yet? Can anyone else help out with a port?

Re: [Matplotlib-users] Basemap to KML polygon
Hi Tim, like I said, I want to convert a filled contours map generated with Basemap (example here : http://imagebin.ca/view/3nYnN3.html) to a polygon shapefile (vector). The filled contours are from a regular points grid which can already be saved into a point shapefile (via ogr python bindings) and I use QGIS to render it. Now I search to get the filled result into a shp file to pass it through ogr2ogr -f KML and render it with GoogleEarth. I know I can do all this process with the QGIS-GRASS interface, but I must limit softwares dependencies 'cause it'll be placed on a web server, and I think Python it's the best choice for doing that :-) After multiple tests, I can retrieve the polygons points coordinates via matplotlib.Patch and save them in a shp file. Now I have troubles with real coordinates and meta-datas, but nothing impossible :-) Tim Michelsen a écrit : Looks like I've done a mistake with my last post, sorry Eli... I know how to save datas to a shapefile with the OGR library but only for points datas. I'll appreciate if somebody can point me how to save a filled contour map basemap into a polygon shapefile, can't find any example with google. What do you really want to save here? A basemap with a contour surface overlayed can be viewed as a assembly of various layers. So this is like the result of the gis operations when you launch the map composer to finish your map. If you want to create a raster file from the contour part plotted over a basemap I think the python bindings of gdal will get you started. http://pypi.python.org/pypi/GDAL/ I succeded into writing a tiff file from a gdal array. I don't know how to write a vector file from python with ogr or shapely. But these questions are better to be asked on the gdal list.: So about interpolating to a contour look at shapely. Writing should be accomplished with ogr. That said, I only have testing experience with writing geodata with python. The overkill may be to invoke the respective GRASS command by a script. I would appreciate if you would tell us what you use by the end.

As I understand it a KML file can be used to specify the Latitude and Longitude extent of a raster image (See 'Ground Overlays' at http://code.google.com/apis/kml/documentation/kml_tut.html). If you can accept some distortion of the text on your image (should be small with a small region) and can work out the size of each pixel in degrees of lat and lon, then all you need to do is write a simple text file to specify where Google Earth should display your Basemap contour map. What you're doing does sound more elegant, but more complex.

Hi Jeff, thanks for the reply.

Thanks Lionel: There's an example in Basemap (warpimage.py) of displaying a plain old png file on different map projections. If you can figure out how to read a geotiff (I've never tried it, but GDAL should be able to do it), you should be able to use the projection information in the file to figure out the lat/lon values of each pixel. Then you could follow the warpimage.py example to transform it to some other map projection. Or, if you want to display it in it's native projection, just use the projection information in the geotiff to define a Basemap instance, extract the rgba values and plot them with Basemap.imshow. -Jeff -- Lionel Roubeyrie - [EMAIL PROTECTED] Chargé d'études et de maintenance LIMAIR - la Surveillance de l'Air en Limousin http://www.limair.asso.fr - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] record array and date support
Hi John,
very very interesting idea.
Is there a way to add some extras informations on the records arrays columns,
like the units or/and the desired labels for the resulting plotted lines,
directly retrieved in the CSV files?
Cordialy
Le jeudi 07 juin 2007, John Hunter a écrit :
I just added support for native plotting of python date and datetime
objects (you still can, but don't have to use plot_date with date2num
conversions). We will continue to do conversion to floats under the
hood, but the conversion can be handled automagically. I also added
support for loading CSV files (or general space/tab/comma delimited
files) into numpy record arrays, and the type conversions (int, float,
date, etc...) happen automagically. The function assumes there is a
header row, and these strings will be munged to give valid python
attribute names. It inspects the first checkrows lines after the
header to try and infer the datatype and set the appropriate
conversion function. It's not entirely bullet proof, but it should
cover a lot of common use cases.
Here is an example (svn only)
from matplotlib.mlab import csv2rec
from pylab import figure, show
a = csv2rec('data/msft.csv')
fig = figure()
ax = fig.add_subplot(111)
ax.plot(a.date, a.adj_close, '-')
fig.autofmt_xdate()
show()
The autofmt_xdate is optional, but is a new function that does a few
things you usually want in date plots: turns off tick labels in the
upper subplots if any, rotates the tick labels on the lowest axes and
right aligns them, and increases the bottom of the subplots adjust to
make room for the rotated tick labels.
Here is what the dtype looks like from the example above.
In [3]: !head -3 data/msft.csv
Date,Open,High,Low,Close,Volume,Adj. Close*
19-Sep-03,29.76,29.97,29.52,29.96,92433800,29.79
18-Sep-03,28.49,29.51,28.42,29.50,67268096,29.34
In [4]: a = csv2rec('data/msft.csv')
In [5]: a.dtype
Out[5]: dtype([('date', '|O4'), ('open', 'f8'), ('high', 'f8'),
('low', 'f8'), ('close', 'f8'), ('volume', 'i4'), ('adj_close',
'f8')])
In [6]: a.date[:2]
Out[6]: array([2003-09-19 00:00:00, 2003-09-18 00:00:00], dtype=object)
I'll probably add a few performance features to the csv2rec function,
mainly to let you skip columns and supply conversion functions where
desired because the autodate parser is pretty slow if you want to
parse date strings, but this is enough to make it useful. Another
useful feature will be able to support customizable type dependent
NULL value conversion (eg convert to numpy.nan for floats,
'-00-00' for dates, etc...)
Record arrays are your friend; have fun!

I tried to convert x and y to degrees, hoping removing the duplicated entries (with rouding) gives me the dimensions, but I also have a problem with m(x,y,inverse=True), because the results are not good ( I use m = Basemap(llcrnrlon=0.5, llcrnrlat=44.8, urcrnrlon=2.8, urcrnrlat=46.5, projection='lcc', lat_1=45.89891889,lat_2=47.69601444,lon_0=2.33722917)). thanks You shouldn't need to do that - just pass x,y and the reshaped z to contourf. You do need to know the parameters of the projection though. -Jeff -- Lionel Roubeyrie - [EMAIL PROTECTED] Chagé d'études et de maintenance LIMAIR - la Surveillance de l'Air en Limousin http://www.limair.asso.fr - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Matplotlib-users] basemap plots
HI, how do you set the arrows on the bottom and the top of your colorbar? I don't find any option for that?

Re: [Matplotlib-users] basemap plots
Arg, sorry, I have found the response by myself, I just have to use figure.add_subplot to fix it. Le Vendredi 07 Juillet 2006 15:14, Lionel Roubeyrie a écrit : Hi Jeff, thanks for the hint, I just need to import one personal GMT file maked a time ago and used in a plotting project based on GMT, which I try to convert to matplotlib. Now I have a little problem to plot a basemap with subplots. Trying to use contour_demo.py mixed with hist.py to have a map with contours and under it an histogram of values, I can't set the colorbar else I loose the map. I think I have a problem with axes but I'm not very familar with subplotting. Have you an idea of how can I do that?

Thanks Lionel: I had included the GMT colormaps in matplotlib, but had to take them out because of licensing issues. If you want to put them back in, put the attached file in your matplotlib install directory sys.prefix/lib/python2.4/site-packages/matplotlib. Then use a text editor to add the following lines to _cm.py (in the same directory) from gmt_cm import addcmaps addcmaps(datad) right above the line # reverse all the colormaps. This will give you the colormaps GMT_gebco GMT_globe GMT_haxby GMT_no_green GMT_ocean GMT_polar GMT_red2green GMT_relief GMT_seis GMT_wysiwyg and the corresponding reversed colormaps (with '_r' appended to the name). -Jeff -- Lionel Roubeyrie - [EMAIL PROTECTED] LIMAIR http://www.limair.asso.fr Using Tomcat but need to do more?
