Mapping and visualization of Point/line/polygon layers
Mapped data can be categorized into one of the general types of map layers: point, line, and polygon.
Each point is defined by X,Y and optionally Z co-ordinates. Field-Map enables the user to measure and attribute points, using laser, GPS, pen, or keyboard.
Lines actually consist of interconnected points in a defined order. Therefore each line is distinguished by its “start” and “end” points. A line usually represents objects with much grater length and width, and may be described in Field-Map by a number of attributes.
Together with georeference, polygons are described by a perimeter and an area. For polygon labeling purposes Field-Map also works with centroids: unique points placed inside polygons.
