Creating a radial traverse
A radial traverse uses 1 fixed reference point to create a traverse relative to that fixed point. In other words, you begin at point A and capture the points around the perimeter of A. You are always standing at the same fixed point but you are capturing multiple vertices.
- Make the polyline or polygon layer editable using the Start/ Stop Editing tool.
- Tap the drop-down arrow next to the Offset Point button.
- Tap Radial Traverse.
- Tap the drop-down arrow next to the Offset Point button.
- Tap Set Reference Point A.
- Tap the screen to set the reference point.Tip:
Enabling the traverse tools: The Linear and Radial Traverse tools will only be enabled if a polyline or polygon layer is set as editable.
Tip:Using a GPS to set the reference points: ArcPad will automatically use the current GPS position for the reference point if data is received from a rangefinder and there is no current reference point defined, and either Offset Point, Linear Traverse, or Radial Traverse are enabled.
- Tap the drop-down arrow next to the Point button and select the Polygon -or
Polyline -feature type.
- With a rangefinder, shoot the target (first vertex) from Reference Point A.
The Point/Vertex dialog box is displayed on the Offset page.
- Continue shooting your vertices from Reference A.
- Tap Proceed when you are finished creating your line or polygon.
The Feature Properties dialog box is displayed with an edit form, if it exists. Enter the information for the new feature.
- Tap OK.
- Your new feature is created.Tip:
Undoing or cancelling your edits: Use the Undo tool to go back a step to the previously captured vertex or use the Cancel Edits tool to erase all edits. These tools are only enabled prior to tapping the Proceed button. Once you tap the Proceed button and tap ok on the Feature Properties dialog box, your edits cannot be undone.
