The Geospatial Tool Kit (GTK) is a small Global Positioning System (GPS) combined with a Windows Mobile Pocket-PC pocket digital assistant (PDA) (e.g., HP iPaq RX-5915). This system was originally developed for a Cooperative Extension outreach program, On-Target. The Geospatial Took Kit combines a surprisingly simple set of tools that bring imagery, GPS, and GIS together into one turnkey, field-based, decision support solution. The Geospatial Tool Kit includes a Pocket-PC PDA, an inexpensive WAAS-GPS, NASA satellite imagery and/or USGS air photos and topography maps through TerraServer-USA, and simple GIS software) that end users can both obtain and use with relative ease. This entire system costs under $1,000, a cost so low that it can be retained by a workshop participant or his sponsoring agency. This has allowed participants to immediately reinforce the critical cognitive-hardware-software linkages upon arrival at their home station following a training event.
