Maptech created a Terrain Navigator Pro web page for surveyors to learn and communicate uses for this software. Terrain Navigator Pro combines USGS topographic maps with aerial photos (DOQQs) at 1-meter resolution. Detailed comments and projects from a variety of surveyors have been collected atwww.maptech.com/land/LandSurvey/index.cfm. (Maptech, Amesbury, Mass.)
