GPSBabel converts waypoint data between about fifty file formats, including Magellan and Garmin serial, Garmin USB, Mapsource, Mapsend, Streets & Trips, Delorme, National Geographic, many PDA formats, and many others. It is endian and word-size safe, includes a GUI, and runs on a variety of operating systems. It also supports Groundspeak GPX extensions for geocaching.
Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.
Wifimap is a Web-based application that graphically documents the organisation and growth of a wireless network community. The map is composed of numerous square cells that are recombined to display the required area. Users can start with just a few cells to cover their area, and can access different areas of the network by scrolling through the cells. New cells can be easily added using a built in editor. Cells can be added at different zoom levels allowing users to zoom in and out of the map. The design makes it very fast, and it can be run on low powered servers. Wireless nodes can be added or edited with a few mouse clicks. Links between the nodes are automatically drawn based on the data entered for each node, and colours are used to represent different wireless protocols.
Stanford Exploration Project Library (SEPlib) is a software package that was developed to manipulate and process many types of geophysical data. It includes libraries for manipulating 2D and 3D data and pipe-fed command-line utilities. It has support for parallelization through MPI and OpenMP and supports connectors to other geophysical packages.
PyTrackProfiler allows you to create high quality PDF route sheets, which useful for planning various kinds of routes (hiking, biking, etc.). It also computes useful information using the track data (time, altitude, etc.) so you can analyze an unknown track. An elevation profile and a projection representation are created. It includes high quality classes for drawing line graphics (XY axis, multi-Y axis, autolabels, autoscale, etc.), parsers for OziExplorer and CompeGPS file formats, support for UTM to latitude/longitude conversion, distance calculation, and angle calculation, support for the Polar HRM hear rate monitor file format, a PDF generator, and more.
