9、nce and Use4.1 The base map,field maps,and the UTM grid lines areused during search operations to ensure that field personnel andthe command post can accurately communicate specific posi-tion information in the search area.4.2 Section 5 verifies if the UTM grid lines are on the basemap or not.If the
10、 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 fieldmaps for personnel to use in the field.4.4 Section 7 describes the uniform way of determining andcommunicating UTM coordinates.5.Verifying and Drawing UTM
11、Grid Lines5.1 Obtain the USGS quadrangle map(7.5 min or 1:24 000)with the area that is to be copied.Review the map to see ifUTM grid lines are marked on the map.If so,proceed toSection 6,otherwise continue with 5.2.5.2 Obtain a straightedge long enough to connect oppositeUTM tick marks and which can
