Max PDOP: PDOP stands for Positional Dilution Of
Precision. It indicates the quality of the GPS position
solution. Low PDOP values are best, and generally a
PDOP of 6 or less will provide adequate accuracy. This
setting tells the software to discard GPS data when the
PDOP is higher than this threshold to help insure the
accuracy of the points that are mapped. Although
setting Max PDOP to a lower value may improve the
accuracy of the points that you map, it may increase
the time that it takes to map the point.
„
Number of Points to Average: Points to average is the
number of GPS data points that you want to average
when mapping a point. Depending on the GPS that
you are using, you may be able to achieve reasonable
accuracy by only averaging a few points (less than 10).
Some GPS receivers may work better when averaging
more points. The more points you choose to average,
the longer it will take to map an object. Typically, each
point takes one second, so 10 points would take 10
seconds to finish (this is dependent on good PDOP,
etc).
