cool screenshot

I just added the orthographic projection to the basemap toolkit - you can now make really nifty pseudo-satellite views of global data.

Here's an example:

http://www.cdc.noaa.gov/people/jeffrey.s.whitaker/ortho.png

This was generated using pcolor by the plotmap_ortho.py example script now in CVS. It requires the pcolor masked-array patch I sent to the matplotlib-devel list this morning. For some reason, pylab.contour goes berserk when you try to contour data on this projection - I;m still working on that.

Jeff,

That is slick! You're using PROJ4, right? I'm happy to see a working application of orthographic projection. We need to talk sometime about how to hook pylab up to GIS data through GDAL/OGR or to web services using WMS/WFS.

cheers,
Sean

Very cool!

At some point in the future we'll be interested in modifying/extending the basemap module to allow other data sets. In particular, we're going to need to do maps of Mars using the Mars laser altimeter database (MOLA).

I wonder if the ability use GIS data sets could be worked in at the same time using some type of common architecture?

Ted,

You mean to do stuff like this: http://zcologia.net/files/mars_topo.jpg ? :slight_smile:

I simply downloaded the most coarse MOLA topography, read it with GDAL, and warped it to an orthographic projection (0 latitude, 0 longitude). GDAL has a SWIG-generated Python module that could be used from pylab. The recipe for this example is at http://zcologia.com/news/39.

cheers,
Sean
