Provided a GPS receiver is connected and operational, the Asset
Surveyor software records GPS positions automatically for the
feature, as determined by the way in which you have configured the
GPS interface. It starts recording GPS positions when you select the
feature and continues recording positions until you save the feature.
If you have configured and activated an external sensor, external
sensor data is also recorded automatically. External sensor data is
recorded until you save the feature.
If you have configured and activated a laser rangefinder, you can
record an offset for the feature by aiming and firing the rangefinder.
Alternatively, you can measure and enter the offset manually.
By taking care of GPS and external sensor data collection, and by
integrating the recording of an optional offset to each feature, the
Asset Surveyor software lets you concentrate on entering attribute
values for the feature.
Each feature is defined as a point, a line, or an area. The way the data
collection software logs GPS positions for points, lines, and areas
differs. Figure 5.1 shows examples of geographical features.
