When designing your network, keep the following principles in
mind:
• Design loops through the network points which resemble a
square or circle. Avoid loops that are long and skinny. Cir-
cular or square shaped loops are stronger geometrically.
• Keep the number of points in each loop fewer than 10.
• Always include a direct link between intervisible points,
i.e. points which may be used as a pair for orientation of a
conventional traverse. Since, in most instances, intervisi-
ble points are relatively close to each other, it is important
to get a direct observation between them.
Observation Plan
With the network design completed, the next step is to deter-
mine how and when data collection will be performed to pro-
duce the desired network. First let’s discuss the how.
If you were to use a conventional total station to perform our
three-point survey example, your resulting traverse could
probably look something like this:
The number of traverse legs required to traverse between each
point in the network will depend upon the conditions on the
ground between the points.
