TAO
is a highly-integrated global positioning system (GPS) interface for real-time
mapping in ArcView. TAO provides full GPS receiver control and continuously monitors
the quality of GPS signals and sources of differential correction to ensure the
accuracy of your GPS positioning. A variety of Trimble and NMEA receivers are
supported. Positions are written to an ArcView shape
file, leaving a “bread crumb” trail for centerline creation. TAO also features
“on the fly” coordinate transformations, and used with ASIA, enables “in-the-field”
map and addressing update capability. Tao 2.0 is available for ArcView 3.x and
is in development for 8.x users.
