There is a good Geodetic Survey of Canada site that has conversion routines to change from lat/lon to UTM and back. The topo maps use a reference system called NAD27, set in 1927. GPS is closer to WGS84, thus there will be slight offsets in position compared to the map. Newer maps will be printed in the newer reference system. Trail Guides

county, and then drew the corners and lines of the surveys onto topographical maps of the county that were published by the United States Geological Survey (USGS). 4 The USGS has mapped much of the United States, including Montgomery County. Most private mapmakers, like Mason, use USGS topographical maps as starting points for their own maps.

Unit and map datum conversions are given in Table 1. NAD83 (geodetic info) is close to WGS84 read out of GPS and both have larger west longitude relative to NAD27 (read from topo maps). The latitude conversion is 2 meters or less and is negligible for this work. Table 1 Length of 1 arc second in feet, and datum shift. Point Length of
