Lab 1-4 Constructing a Field MapTake out the lab on “Constructing a Field Map.”
Start by choosing a value which is in the middle near the middle.Huh?In other words: you want a value that is both away from the edges and in the middle of the range of values on this map.This will give you the best chance of starting with a complete line.Find all the 22 degrees marks & darken them with pencil.
USE PENCIL!
Not enough points to get a good pattern?Add some data points.Just because there are no more 22’s doesn’t mean they don’t exist.22 belongs between 21 and 23, (etc.).
Now connect the dots with a smooth curve.
Do not go past the edge of your map. You have no data from which to make a pattern.
Now go to the next higher or lower value.
