What is a “Topic” in PC-GPS?
A Topic is a layer of data in the PC-GPS Map. A Topic contains Features, which are defined by a common set of Attributes. A Map file may contain a number of different Topics. For example, the Map may have a Tree Topic, a Road Topic, and Sale Lot Topic. Non-spatial data, such as text, objects, and shapes can also be assigned to specific Topics in the Map. The Topics in the Map are listed in the Topic View. The display of Topics in the Map View can be toggled OFF and ON. Topic organization facilitates efficient data analysis and GIS export.
