Lesson 1 of 9

Introduction to Topographic Maps

1Tap anywhere on the sheet. Its MGRS grid reference appears below: grid zone, 100 km square, then easting before northing.
2Change the precision from 4 to 10 figures and watch the same place named by a smaller and smaller square.
3Turn the map and zoom in. The reference of your selected location does not change.
4Choose Ruler, press for a start point and drag to an end point. Read the distance in metres and kilometres.
5Tap a brown contour line to read its elevation, and find the hilltops and the creek valley from their shape.

Compass

Bezel 000° · declination 0°

Tap any component of the compass to inspect it.

Bezel at the index line: 000°
Declination set on the screw: 0°
On the map at: Not on the map

On the map: drag the compass to move it, drag its rear end to turn it, and drag the ring to rotate the bezel. Its settings stay as you leave them in every lesson.

Grid reference

Tap the map

Precision: Names a 1 m square

Precision is not accuracy. More digits name a smaller square; they do not make the map, or your plotting, any more exact. On a 1:50 000 sheet a careful reader is good to about 50 m.

Ruler

No measurement

Press on the map for the start point and drag to the end point. Drag either end to adjust it. The distance comes from the grid coordinates, so turning or zooming the map never changes it.

Markers

No markers yet. Choose Marker above the map, then tap the sheet.
