The following is a list of geodetic tools available at Natural Resources Canada.

• CSRS-PPP An online Global GPS Processing Service - Process RINEX observations from single or dual-frequency receivers operation in static or kinematic mode.
• GPS·H Transforms Canadian NAD83CSRS/ITRF ellipsoidal heights to orthometric heights compatible to CGVD28 (height above mean sea level) using HT2_0 model.
• GSRUG Converts between Geographic and UTM coordinates.
• INDIR Perform either a geodetic direct or inverse computation.
• NTv2 Transforms between NAD27 and NAD83(Original) geographic or UTM coordinates. *
• GPS calendars These calendars will help you convert a typical calendar day to either the Day of Year or GPS Week number.
