PP3 creates celestial charts. It generates resolution independent maps of very high graphical quality. They can be used for example as illustrations in books or on web pages. You may use own databases or free ones from the Internet.

ptiger is a Tcl/Tk/Tkgeomap script that uses wdgeomap to display U.S. Census Burea populated places on an interactive geographic map. To run it, type ptiger on the command line. After a few seconds, a map should appear. Adjust the view by Dragging or Double-Clicking. As the cursor moves, a label below the map displays the cursor location and the azimuth and range from the + marker to the cursor. Move the + marker by Right-Double-Clicking. The map has dots at places with population greater than a user selected threshold. Moving the cursor over a dot labels the place with its name and displays the population in another label below the map. In addition to the wdgeomap menus, a Places menu enables adjustment of the population threshold and dot size. There is also a Find menu that does a case insensitive regular expression search for a named place.

py-aipy collects together tools for radio astronomical interferometry. In addition to pure-python phasing, calibration, imaging, and deconvolution code, this package includes interfaces to MIRIAD (a Fortran interferometry package) and HEALPix (a package for representing spherical data sets), and some math/fitting routines from SciPy.

astLib is a set of Python modules that provides some tools for research astronomers. It can be used for astronomical plots, some statistics, common calculations, coordinate conversions, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Doug Mink. PyWCSTools is distributed (and developed) as part of astLib.

Astropy is a package intended to contain core functionality and some common tools needed for performing astronomy and astrophysics research with Python. It also provides an index for other astronomy packages and tools for managing them.

PyFITS provides an interface to FITS formatted files under the Python scripting language. It is useful for interactive data analysis and for writing analysis scripts in Python using FITS files as either input or output. PyFITS is a development project of the Science Software Branch at the Space Telescope Science Institute.

Pymetar is a python module and command line tool designed to fetch Metar reports from the NOAA (http://www.noaa.gov) and allow access to the included weather information.

PyEphem provides scientific-grade astronomical computations for the Python programming language. Given a date and location on the Earth's surface, it can compute the positions of the Sun and Moon, of the planets and their moons, and of any asteroids, comets, or earth satellites whose orbital elements the user can provide. Additional functions are provided to compute the angular separation between two objects in the sky, to determine the constellation in which an object lies, and to find the times at which an object rises, transits, and sets on a particular day.

QLandkarte GT is the ultimate outdoor aficionado's tool. It supports GPS maps in GeoTiff format as well as Garmin's img vector map format. Additional it is the PC side front end to QLandkarte M, a moving map application for mobile devices. And it fills the gap Garmin leaves in refusing to support Linux. QLandkarte GT is the proof that writing portable applications for Unix, Windows and OSX is feasible with a minimum of overhead. No excuses! QLandkarte GT does replace the original QLandkarte with a much more flexible architecture. It's not limited to a map format or device. Thus if you think your Magellan GPS or other should be supported, join the team. Additionally it is a front end to the GDAL tools, to make georeferencing scanned maps feasible for the normal user. Compared to similar tools like QGis, it's target users are more on the consumer side than on the scientific one. QLandkarte GT might not let you select every possible feature of the GDAL tools, but it will simplify their use to the demands of most users.

Python script that downloads weather data and can be cron'd.
