GSRUG - Online UTM parametersZone Width = 6º Zone numberScale factor = .9996False easting = 500000.0mFalse Northing = 0.0m FEDERAL MTM parametersZone Width = 3º Zone numberScale factor = .9999False easting = 304800.0mFalse Northing = 0.0m Some provinces have different MTM zone definition, use different false Easting, use different zone widths
GSRUG - DOS 5 parameters for TM projection GSRUG could also produce PointScale Factor
Ellipsoidal distance INDIR - Online DIRECT Geographic coordinates
INDIR - Online INVERSE
GPS-H - Online Only applies HT2 Height Transformation
GPS-H - Windows Can apply any Geoid Model Allows entry of control BM(s) for applying vertical bias(point or plane)
