I work for a Civil Engineering organization. I need to give our users a
means to generate geographic coordinates for our projects and structures.
I plan to do this by making a viewer which will accept a graphic file and
two points (pixels) in that image for which geographic coordinates are
given. Users can then click on the image where appropriate to generate a list of
geographic points of interest for their work. The list will be saveable as an
xml file or a shp file (a widely used geographic binary format.) In addition,
other programs that I write will use the viewer as a dialog box: will
call the viewer directly and get the points from it, just like a color picker
dialog.
What I am looking for: thoughts on which Python modules are most
appropriate and generally applicable for this. PIL? Piddle? PyGIS? some of
Hobu's modules? I believe I can write the glue-code, but I don't want to
reinvent the wheel if there are existing modules that do
almost (or even better, exactly) what I need.
I work on WinXp, Linux, and WindowsCE. WindowsCE has a fairly
plain-vanilla Python build, so it's better if I stick to the core modules as far
as possible.
