UTM (Universal Transverse Mercator) 10 Km Grid

Many geometrical schemes - or map projections - are used to represent the curved surface of the Earth on map sheets.

Canada uses the Universal Transverse Mercator (UTM) system. It is called transverse because the strips run north-south rather than east-west along the equator.

This data class shows a 10 km x 10 km coordinate system based on the UTM projection using the North American Datum 83 (NAD83) grid.

It includes:

Military Grid Reference- identifies a specific military grid reference system grid cell
Fire Base Map identifier- five digit identifier used by MNR's Aviation and Forest Fire Management Program to identify a fire basemap
Atlas identifier - identifies a specific grid cell
UTM Map Sheet Number - ID number of a UTM mapsheet

This product requires the use of GIS software.
