Geodetic Transformation
- GSD95 (QUAD V 2.0) Undulation Modelling within Canada to derive geoid/ellipsoid separations of static and kinematic GPS positions prior to aerotriangulation
- HT 1.01 Undulation Modelling within Canada to derive geoid/ellipsoid separations of static and kinematic GPS positions prior to aerotriangulation using the Southern Ontario Adjustment and either the NAD83 or the ITRF96 ellipsoidal models.
- GSRUG to convert between Canadian geographic (latitude/longitude, ellipsoidal) coordinates and UTM or MTM equivalents within a number of datums.
- CONV77.EXE to convert coordinates from NAD83 or NAD27 ellipsoidal values to the A.T.S.77 ellipsoid and the New Brunswick Stereographic Grid system.
- INTGRID to convert Canadian coordinates from one datum to another. (This is necessary if historical data is in NAD27 or similar and needs transformation into NAD83 or WGS84 or ITRF96.)
- CORPSCON V. 5.1 to convert U.S. geographic coordinates from one datum to another, and to either U.T.M. or State Plane Coordinates. (Also contains Vertcon to convert orthometric height values from NGVD 29 to NAVD88 vertical datums.)
- GEOID99 to convert WGS84 ellipsoidal heights to orthometric heights within the coterminous U.S.
