Map Making- Hypothetical Example: The Tell-tale Tricks
Have you drawn a map of an 'L' shaped field? If not, click here to get the instructions for that.
If you HAVE drawn the 'L' shaped field, AND checked your work.... then scroll down this page to learn of the two 'tricks' in the data you were given......
The tricks are to help you see if you are REALLY drawing things according to the data you have, or whether you drew what you thought the map should be rather than what the data called for.

These were the two things which SHOULD be on you map, even if they look 'wrong':
If the fence between A and B goes exactly North-South, then the corner at D is slightly east of due north from C. (All other fences are parallel or perpendicular to one another.)
The line from G to E passes slightly north of the point you would mark as E if you only had the bearings from A and B to go on.
In real life, you would be working very successfully if you had three (or more) lines cross neatly at a single point the way they did for most points in the hypothetical exercise. However, if the three lines nearly cross, you get a small triangle. The point you are trying to put on your map will be somewhere within that triangle. Small triangle, small margin of error!
