Converting E00 Vector Data To Shapefiles – A Free And Fairly Painless Approach
Contains the utility ArcInfo2ShapeGUI, a front-end for ogr2ogr that along with the ESRI program Import71 can convert E00 files to shapefile format.

A GUI For Fixing the GPSVersionID EXIF Tag
Some geotagging applications (locr, the Microsoft WMMX apps) embed a GPSVersionID tag in the EXIF headers of JPEG files that Picasa can’t recognize. Consequently, Picasa ignores all of the geotagging data embedded in these files. This utility is a front-end to EXIFTool, which re-writes that GPSVersionID tag to one that Picasa reads and accepts.

Converting OpenStreetMap Data Into GPX Or Garmin .img Format
You can convert street map data from the Open Street Map project into Garmin .img files using the command-line Java utility Mkgmap. I’ve created a simple Windows GUI for those who might find that easier than using the command line.

Embedding Time Data Into A Google Earth KML File
Google Earth can use time information embedded in KML files to create animations. But there’s no way to enter this data into a KML file using Google Earth; you have to either create it in a utility that supports time data, or directly edit the KML file to include it. I’ve written a simple utility to offer a third option, that with some limitations can embed time data into any KML file.

KML Time Code Utility
Derived from the above utility, this simple one lets you enter time parameters for a KML TimeSpan or TimeStamp, then generates the corresponding KML code. You can then copy and paste this code into your own KML file.

KML Screen Overlay Maker
KML screen overlays are graphics that sit fixed in the Google Earth display screen, not draped over the terrain like ground overlays or placemarks/paths/polygons. There’s no way to create a ScreenOverlay in Google Earth, so up until now you had to create it directly in KML code. This utility lets you create one without doing any KML code writing, and also lets you change the position of the overlay and see the modified overlay in real time in Google Earth through a network link.

GUI for Libgeotiff utilities
The libgeotiff utilities are command-line programs that both extract worldfiles and full geometadata from GeoTiff files, and can embed the data back into Tiff files from which that information has been removed (e.g. if you modify the Tiff file in a graphics editor that strips out the data when you save the file). This utility is a simple GUI front-end for those command line utilities, to make using them a bit easier.

Raster Image Metadata Extractor/Viewer
A simple utility that extracts the geographic metadata from compatible raster image formats (GeoTiff, MRSID, ECW, BSB and JPEG2000), saves it as a text file, and also displays it.

Triton RMP Helper
Re-projects a GeoTiff to geographic coordinates/WGS84, and extracts calibration data so that the raster image can be processed by Triton RMP Maker into a format compatible with the Magellan Triton series of GPS receivers.

G-Raster
Converts Google Earth KMZ overlay files and georeferenced imagery into the standard KMZ format for raster imagery supported by recent Garmin handheld GPS models (the Colorado, Oregon and Dakota series).
