Tools and Tutorials

No need to spend a bundle on software for making your own maps. The free programs listed here can keep you engaged for months and may be all you need for projects. For additional functionality, the reGIStration fees for many of the programs are economical. When you are ready, trials of mainstream professional programs from companies like Adobe, ESRI, MapInfo, MapTech and many others are interesting, too.

Data and Metadata

There is a wealth of free data available on the Internet, but be realistic about what you try to download. If you have an ordinary analog dial-up modem, you will be less frustrated by using small data sets. For example, Digital Line Graph (DLG) files showing roads and streams or 30-meter resolution Digital Elevation Models (DEM) are often only 200-300KB in size, which are easy to download. Single TerraServer aerial photos will generally load well with a standard modem link. USGS topographic maps (DRG files) are about 2MB in size. Landsat images and Space Shuttle Radar DEM files are typically 30MB and larger, requiring a broadband connection. In addition to free data, many of the following sources offer inexpensive commercial data.
