4.1 The base map, field maps, and the UTM grid lines are used during search operations to ensure that field personnel and the command post can accurately communicate specific position information in the search area.

4.2 Section 5 verifies if the UTM grid lines are on the base map or not. If the UTM grid lines are not on the base map, Section 5 describes how to draw them on the map.

4.3 Section 6 establishes how to set up and prepare field maps for personnel to use in the field.

4.4 Section 7 describes the uniform way of determining and communicating UTM coordinates.

1.1 This guide describes one method of setting up a Universal Transverse Mercator (UTM) grid system on a base map for transfer to a field map.

1.2 This guide provides a uniform way of communicating UTM coordinates.

1.3 This guide is intended to be used with United States Geological Survey (USGS) 7.5-min quadrangle topographical maps with a scale of 1:24 000, with or without UTM grid lines.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
