The collection process begins by occupying the defined point, line, and area. A line and area are kinematic activities with spatial data collected on the move. As a result, point features have better spatial accuracy than line or area features. During data gathering, the data dictionary attributes and values are entered and logged to spatial features. A road is a typical line feature.
Data collection begins on the road centerline.
The data interval is normally five seconds. An area is similar to a line feature except it closes to form a polygon. A lake, pond, tennis court or parking lot are typical area features. In addition, area features may mark vegetation, archeological sites or contaminate areas. GPS data gathering begins on any area location.
