Step 1
mark the spot that you want to find in the middle of the paper. This will be your base elevation.
Step 2
Determine how much elevation detail you are going to record. in drastic terrain, you may measure changes of 20 to 50 feet. In less drastic terrain, it may be 5 to 10 feet.
Step 3
Draw a circle around your spot based on how much area is the same elevation around your spot and where the decided-upon elevation change occurs.
Step 4
Note the severity of change in the elevation you can see in a 360 degree view from where you stand. These lines will be close together because the elevation change is drastic.
Step 5
Use contour lines as you walk to a major landmark
Step 6
When you arrive at a major landmark (road, river, etc.), survey and note the elevation changes for the entire area surrounding the spot where you have intersected with the landmark
