Georgia Department of Transportation (GDOT) has a large number of ArcView GIS users making a wide variety of maps for purposes from planning and traffic to historical sites. Having access to a library of State-wide coverages gives users the ability to make their own maps. With increasing user sophistication has come increasing demands including the capability of putting their own data on top of the standard GDOT maps for display. Production of these maps, including the State transportation map and the 159 county road maps, has recently been transitioned from manual methods to a GIS process. A variety of methods were explored to help people use the standard map products as a base. Adding the map as an image theme in the form of a georegistered TIFF in ArcView GIS was the one chosen. GDOT needed techniques that would allow timely production of quality maps with a variety of data using software and data available to all. Serving the standard GDOT maps as georeferenced images lets users view and plot their data in a cartographically pleasing manner, taking advantage of features and annotation on the image. The process of making maps in a map composition, using ArcPress to produce a TIFF, and then using ArcInfo to register the image has proven to be a success at GDOT.
