Earth mapping and GPS applications

This suite of applications demonstrates a number of Python features:

• Image processing using the Python Imaging Library (PIL).
• Scientific and mathematical computation using standard libraries.
• Graphical user interface programs for browsing mapping data with superimposed GPS (Global Positioning System) coordinates.
• Use of the SOAP (Simple Object Access Protocol) to access Web services, in particular, the TerraServer Earth-mapping data service.
• Use of XML for record-keeping.

Documentation and source files for the application

• A Python mapping package: User and internal documentation. Also available in PDF format.
• wayimage: Script to produce a map image file with superimposed GPS waypoints.
• waypointset.py: Python module to access stored sets of waypoints.
• waypointsDTD.py: Python definitions relating to the waypoints XML document type.
• mapbase.py: Module to access base maps.
• mapframe.py: A composite Tkinter widget, MapFrame,to show maps on a scrollable canvas.
• latlonentry.py: A Tkinter widget that allows entry of a lat-long coordinate.
• routebox: Script to find the geometric limits of a given set of waypoints.
• terrapos.py: Python module to represent terrestrial positions.
• buildmapbase: Script to download map images from the Web through a SOAP interface.
• wayplot: A graphical browser for a map with superimposed waypoints.

Modules from the author's Python library

• canscroll.py: Canvas with scrollbars for x and y.
• dropdown.py: A composite Tkinter widget, DropDown, for drop-down menus.
• dom_helpers.py: Some Python functions to assist in generating XML content.
• sysargs.py: Python module to assist in command line argument processing.

External modules

The pyTerra module from hobu.biz handles the actual SOAP interface connection.
