Description

The Electronic Distance Measurement (EDM) Calibration Baseline Lengths listings give the pillar-to-pillar (slope distance) baseline length values for the four EDM calibration baselines in Alberta (Lethbridge, Calgary, Edmonton and Grande Prairie). These values are based on precise measurement and adjustment undertaken by Geodetic Survey Division of Geomatics Canada (NRCan). All of the baselines are re-measured and adjusted, and new values published on a five-year basis. Please note that on each listing, there is an adopted date that signifies when the slope distances were formally published by the Surveys Section

Description

The Guidelines for Electronic Distance Measurement Calibration Baseline Surveys in Alberta describe the four EDM calibration baselines in the province of Alberta, as well as how to undertake an EDM calibration baseline survey. The guidelines have been developed to assist users in verifying that their EDM equipment is working within the EDM manufacturer’s stated specification for scale error and constant error. They also include requirements for submission of EDM calibration survey data to the Surveys Section for evaluation.
