Overview of polygon features

ArcPad has the following tools for creating polygon features:

• Rectangle: This tool creates a rectangle using the coordinates from where the pen first touches the screen to where the pen is lifted. The rectangle is automatically completed when the pen is lifted.
• Polygon: This tool captures a vertex each time the pen taps the screen or each time the Add GPS Vertex button is tapped. The Add GPS Vertices Continuously button can also be used to capture vertices from the GPS. Offsets can also be used to create vertices for a polygon. The polygon is completed when the Proceed tool on the Command bar is tapped.
• Ellipse: This tool creates an ellipse using the coordinates from where the pen first touches the screen (the origin) to where the pen is lifted (the radius). The polygon is automatically completed when the pen is lifted.
• Circle: This tool creates a circle using the coordinates from where the pen first touches the screen (the origin) to where the pen is lifted (the radius). The polygon is automatically completed when the pen is lifted.
• Freehand Polygon: This tool creates a sketch polygon based on the line drawn with the pen. The polygon is automatically completed when the pen is lifted.

All of the polygon tools can be used with the mouse pointer or pen. The Polygon tool can also be used with the incoming GPS coordinates or with offsets.

All of the polygon features are created in a polygon layer—a shapefile, an ArcPad AXF layer, or a graphics layer. The new polygon feature is stored as x,y and, optionally, z coordinates.
