Large scale topographic maps portray detailed information about the landscape. They are used for a wide variety o f purposes. USGS large scale topographic maps at 1:24,000 have been traditionally distributed in paper form. With the advent of the Internet, these maps can now be distributed electronically. Instead of common raster format presentation, the solution presented here is based on a vector approach. The vector format provides many advantages compared to the use of a raster-based presentation. This research shows that Scalable Vector Graphics (SVG) is a promising technology for delivering high quality interactive topographic maps via the Internet, both in terms o f graphic quality and interactivity. A possible structure for the SVG map document is proposed. Interactive features such as toggling thematic layers on and off, UTM coordinate readout for x, y, and z (elevation) were developed as well. Adding this type of interactivity can help to better extract information from a topographic map. A focus group analysis with the online SVG topographic map shows a high-level of user acceptance.
