Our Global Positioning System (GPS) Position Data Graphical Viewer combines the utility of GPS with Computer Aided Design & Drafting (CADD) graphics in a real-time environment. GPSView provides a graphical interface to any NMEA compliant GPS receiver which outputs GPGGA position messages.

GPS real-time position information is plotted on a vector graphic map display created by MicroStation, but does not require MicroStation for viewing. Geodetic conversions from Latitude/Longitude NAD 83 to the user's East/North coordinate system is provided by integral Corpscon software. GPSView allows an operator to define a display coordinate system based upon Projection (UTM or State Plane), Zone (UTM Zone 1-60 or SPCS Zone), Horizontal Datum (NAD83 or NAD27), and Units of Measure (Survey Feet, International Feet, or Meters).

Flexibility in windowing capabilities is provided through a self-scrolling display window, windowing controls based upon GPS position, or manual windowing controls. Stored data can be annotated with non-graphic key-in data such as feature, condition, comments, etc. Our GPS viewer provides automatic readouts of projected Easting/Northing coordinates as well as Latitude/Longitude and the complete GPS message received. Current speed and bearing are shown in addition to a vector that shows your position at a selectable future time if the same heading and speed are maintained. If features such as baseline stations, mile posts, or river miles are contained on specific levels of the viewer file then automatic readouts provide interpolated values for these features. Waypoint navigation allows an operator to graphically select a point on the screen. Display fields then show the range, bearing, and estimated time of arrival to the point. Additional navigation features include range rings which can be displayed at any selected interval centered at the current GPS position.
