Why doesn Grid North correspond to True North?
Grid North pertains to the north for a specific plane coordinate system. All north-south lines run parallel to one another in the UTM projections. True North refers to geodetic or geographic north pole, and the lines of longitude converge on the 7.5’ maps. Because the 7.5’ maps mix the UTM and conic projections occasionally the UTM grid will appear at a small angle to the neatlines (a line separating the body of a map from the map margin) of the map. This is not a cause for concern so long as the UTM grid has been drawn in correctly by the user. 8. How do I report a position? If coordinates are to be passed on to another person it is technically necessary to report the horizontal datum and the latitude/longitude of the point (e.g. NAD 27 CONUS, 44 degrees, 7 minutes, 30 seconds north/ 104 degrees, 15 minutes, 10 seconds west). If using UTM, include datum, grid zone number, row indicator, easting and then the northing value (e.g. NAD 83/13 S/ 0404524E/ 4239242N). UTM coordinates are alw
