The following are links to other software and websites which have some relation to GPS systems, coordinates, mapping, exif and other good stuff. A mention here isn't necessarily a recommendation, but a starting point. Most of the software here is gratis, free and open source, and these are marked with the symbol (free). Some are gratis but closed-source, and some require payment to work properly.
These are applications for editing, viewing or converting coordinate data from GPS receivers. Most of these concentrate on manipulating the data after it has been recorded, rather than working with live data.
Easy to use java program (made by this website activityworkshop.net) for viewing, editing and converting GPS data, showing your GPS tracks in 2d using openstreetmap or in 3d, and drawing charts. Also correlates photos automatically with the GPS data to either write the coordinates in the exif tags of the photos or to export thumbnails to KMZ format for Google Earth. Supports text, csv, GPX, KML, KMZ and NMEA formats, and uses gpsbabel (see below) for loading data from GPS receivers and sending it back again.
Home page activityworkshop.net/software/gpsprune.
Specialises in conversion of coordinate data between file formats and data formats, including communicating with countless GPS receivers for download and upload. Can be run either from the command line or from a GUI. Called by GpsPrune to receive data from a GPS or to send data back.
Runs on Linux, Mac and Windows. Source code available.
Wikipedia page en.wikipedia.org/wiki/Gpsbabel, home page gpsbabel.org.
Linux program to automatically correlate photos with gps tracks (in GPX format) using timestamps. It's similar to Prune's autocorrelate function. Can be run from the command line or using a gui called gpscorrelate-gui.
Home page freenote.dview.net or see Ubuntu's package information for gpscorrelate-gui.
Linux program to extract data and screenshots from Garmin GPS receivers. Command line only.

Home page routeconverter.de.
(free) Command line java tool for automatically correlating photos with a GPX track and writing the coordinates to Exif. Doesn't rely on Exiftool to do the writing. Development appears frozen at release candidate stage, with no future releases planned. Should be cross-platform, described as "open soorce" (sic). Home page at wiki.hsr.ch (suspended).
Comprehensive GIS tool with some GPS-related functionality, including downloading data from GPS receivers using Gpsbabel and overlaying on other geographical data. Also loads delimited text files and Gpx files. Runs on Linux, Mac and Windows. Source code available.
Wikipedia page en.wikipedia.org/wiki/Quantum_GIS, home page qgis.org.

Sourceforge page qlandkarte.sourceforge.net.
Overlays GPX data on maps. Bit of a quirky interface but many features including uploading to Openstreetmap. Runs on Linux and Windows. Source code available.
Home page sourceforge.net/projects/viking, also OSM wiki.
Provides realtime location information from a receiver and overlays position on openstreetmaps or other images. Also shows trip information and can save NMEA track logs (which can then be loaded into Prune). Requires gpsd to communicate with the receiver. Really intended for linux handhelds but also runs on other linux systems. Source code available.
Home page tangogps.org.
Command line tools for working with GPX files, including charting using gnuplot. German only, but runs on Linux, Mac and Windows. Source code available but requires installing a mercurial client to get to it.
Home page von-und-fuer-lau.de.
Extremely interesting idea, of matching mountains from photographs and telling you what all the other mountains in the picture are. Sounds great, but despite several attempts it never seems able to get it right with my photos. Quirky interface and poor data don't help either. Pity. May be worth another look.
Home page flpsed.org/gipfel.html.
Graphical editor doing many of the same things that Prune does, including a map view and profile view, point deletion and so on. Supports multiple languages including French and German. Attempts to be cross-platform (written in Delphi) but relies on Internet Explorer so effectively Windows/Wine only. Source code available. Only has a blog entry as reference.
Blog entry knackes.com/blog/index.php?2008/11/20/193-gpx-editor-1070.
Command line tool written in java to convert OSM files (extracted from openstreetmap) into IMG files for GPS receivers. Source code available.
Wiki page wiki.openstreetmap.org/wiki/Mkgmap.
Track management tool based around a calendar of "activities", each with GPS tracks and descriptions. Loads gpx files and shows overlays using Openstreetmap, charting, distance/speed calculations and more. Currently (at the time of writing) at version 0.2 and only runs on linux. Source code (C++ and qwt) available.
Home page activitydiary.org. (looks dormant)
Simple track viewer using openstreetmap overlays. Impressively small size for what it does. Python, apparently linux-only? Source code available, relies on the separate
osm-gps-map library to do most of the work (see below)

For more links to free software tools, see maps-gps-info and their extensive list categorised by platform.
The following links to non-free software is arranged alphabetically rather than in order of importance / recommendation.
Closed source, Windows-only, gratis / 35 EUR. The gratis "easy" version apparently just does data transfer to/from GPS receivers, the paid-for "expert" program offers mapping, elevation charts and data editing functions. Home page topografix.com.
Closed-source, Windows-only program for downloading data from Garmin and Magellan GPS receivers, and editing and charting the data. Limited functions until purchased for EUR30.

Another Mac-only, closed source application costing EUR 29 plus VAT. Views include Google maps, calendar views and simple charts. Home page rubitrack.com.
Claims to be under the BSD license, but I can't find any sources, only a linux binary. It offers many of the same functions as Prune, including OSM overlays on data, calling gpsbabel to extract data from a GPS receiver, correlation of photos using timestamps, creation of height profiles, and even use of the Shuttle's SRTM data for altitudes. Gratis but linux-only. Home page ruessel.in-chemnitz.de/tkosm
Another Mac-only, closed source application this time asking for donations of EUR 25. Includes an interesting set of features such as links to gpsies, multiple map backgrounds and nice-looking charts. Home page trailrunnerx.com.
These utilities might be hidden in the background, but they're extremely useful and often used in conjunction with GPS software.
Java library of functions by Drew Noakes to allow programs to extract metadata from for example Exif blocks in Jpeg images. Used by Prune to read timestamps, GPS coordinates and thumbnails from photos. Source code available.
Home page drewnoakes.com/code/exif.
Command line perl tool for reading and writing metadata in for example photo files. Called externally by Prune (if it's available) to write coordinates in the Jpegs. Runs on Linux, Mac and Windows. Source code available.
Home page sno.phy.queensu.ca/~phil/exiftool.
A Gtk-based widget which handles the display of coordinate data with a choice of overlays including openstreetmap and mapsforfree. According to the home page it originated from the code in
tangogps (see earlier). Intended to be included in other applications, many of which could be mobile.
Home page nzjrs.github.com/osm-gps-map.
These are programs not necessarily related to GPS systems but general 3d modelling and rendering programs.
The granddaddy of 3d rendering software, a gratis cross-platform ray-tracing program. Prune can output models in .pov file format for rendering by Povray. It has a host of rendering configuration options, and can be run from the command line or from a Gui.
Runs on Linux, Mac and Windows. Source code available.
Wikipedia page en.wikipedia.org/wiki/Povray, home page povray.org.
Povclipse is an eclipse plugin to make editing of pov models easier. However I was never able to get it to work properly.
Runs inside eclipse, so cross-platform.
Sourceforge page povclipse.sourceforge.net.
KPovModeler is a modelling program for creating and editing pov models. Again I was never able to really get this to work properly or get it to understand the pov models from Prune.
Runs on KDE, which means (for now) Linux-only.
Home page kpovmodeler.org.
These are websites related to mapping, geotagged photos and GPS plotting.
Actually this should probably be listed under "software" rather than "websites" - it's an impressive set of utilities for conversion and manipulation of data at gpsvisualizer.com. With it you can upload data and generate maps, kml files and other plots.
gpsies.com is a very useful resource for viewing and downloading tracks which other people have posted. Download options include KML and GPX, among many others. Tracks available in dozens of countries worldwide.
alpin-koordinaten.de is a German language resource for coordinate data. Despite the name it doesn't just cover the Alps, but this is where the vast majority of information is. You can search for coordinates and download in various formats, but the data quality is variable and many points have multiple coordinates (sometimes identical, sometimes worryingly different).
The well-known maps.google.com has worldwide coverage and a fast, draggable interface. Also includes search functions, and even driving directions. Zooming in brings further information such as tram times.
A Swiss-specific map site, map.search.ch, has excellent local information including train times, hotels and so on, and a smooth zoom function. Useful layer functions including for example hotels, restaurants, and train stations (including train times).
The ambitious free mapping project at openstreetmap.org aims to provide free worldwide maps based on volunteer data. Coverage in some places is lower than the commercial offerings, but growing, and in some areas the details is actually better. And the data can be used without restriction. This is the source of the map images used by Prune including the opencyclemap and openpistemap extensions. It's also got a great wiki and is also a source of free maps which you can download to the memory cards of GPS receivers.
The popular photo-sharing site flickr.com includes geotagging of photos, and a simple interface for assigning coordinates to photos. Requires user registration.
Another photo-sharing site locr.com concentrates on the idea of geotagging photos (rather than that being an optional extra). Requires user registration to submit photos but anyone can browse using the map.
Panoramio.com used to be a useful source of photos tagged with GPS coordinates, so you could use a Google Maps interface to find good-quality photos of a given area. GpsPrune also used to have a function to launch a browser showing the panoramio map of the current area. But the site has now been discontinued by Google.
Like a cross between GpsVisualizer and gpsies, this website / software (previously at gobreadcrumbs.com) was a mix of personal track management (using GPSBabel or garmin browser plugins), track editing (deleting, moving, adding points) and also track publishing and sharing. Browsing the published tracks didn't require registration, but the site seems dead now.
