"The Graphic Corpscon
for Geodetic Calculations and Batch Reprojections"
|
Our Geodetic Translator incorporates CORPSCON, which is itself composed of NADCON and VERTCON, as developed by the National Geodetic Survey (NGS) and the U.S. Army Corps of Engineers. Geodetix provides a graphical interface to this standardized geodetic calculation software used throughout the surveying, mapping, and cartographic community. Our Geodetic Translator, Geodetix, is based upon DgnView, our Design File Viewer, for simplicity and uniformity across all of our various graphic applications. Geodetix allows an Operator to define an input and an output coordinate system based upon Projection (UTM or State Plane), Zone (UTM zone 1-60 or SPCS Zone), Horizontal Datum (NAD 83 or NAD 27), and Units of Measure (Survey Feet, International Feet, or Meters). Selectable input methods include key-in of Latitude/Longitude, key-in of Easting/Northing, or Graphical input using the mouse. Whenever the Convert button is pressed for key-in inputs, or the mouse is moved for Graphical inputs, Geodetix performs three CORPSCON calculations. It calculates Latitude/Longitude in the Input coordinate system based upon East/North key-in or Mouse position, and also calculates both Latitude/Longitude and East/North in the output coordinate system. These coordinates are displayed continuously as the mouse cursor is moved around the display window. Precision inputs are provided either by key-in inputs or by graphically "snapping" to a point in the graphic window. Batch translation capabilities are provided for converting graphic vectors in one coordinate system to vectors in an output coordinate system. This creates a new viewer file in the output coordinate system which can then be re-imported back into MicroStation. This process provides an easy, simple way of converting a design file from one projection into another. Although Elevation cannot be displayed on the graphics window, Geodetix does perform geodetic calculations in the vertical dimension. Input and Output elevation coordinate systems are defined based upon Datum (NGVD 29 or NAVD 88), and Units of Measure (Survey Feet, International Feet, or Meters). This calculation is performed as a result of key-in values or by graphically "snapping" to a point.
