What data is available in SDTS?
SDTS has been mandated as a federal standard, so most current data sources will be federal agencies. Below you will find a list of some federal agencies who have or will be offering SDTS data. (data sources will be updated as they come to our attention) 3.1 United States Geological Survey (USGS) The USGS is making much of its digital map data available in SDTS as an additional distribution format. By producing data in SDTS format, the USGS hopes to create a demand for the data and software to read it. This will make it profitable for commercial software developers to write viewers and decoders for using the data. All USGS map data continues to be available in native formats. Sales policies for native-format data have not changed. The USGS has no plans to abandon any of the older formats. To promote SDTS as a GIS format, USGS SDTS data is available over the Internet at no charge. USGS data and products are not generally free; SDTS data is an exception.
