Creating a new point feature using a 2 point offset

A 2 point offset enables you to create a point based on two reference points (A & B). The reference points can be set using a pen, GPS, or manually entered coordinates. There are two variations available in ArcPad for the 2 point offset: distance– distance and bearing–bearing.

Steps:

1. Make the point layer editable using the Start/Stop Editing tool.

2. Tap the Offset Point button.

   The Offset Point button is depressed on the Edit toolbar and a red box is placed around the Offset Point button in the drop-down list to indicate that it is active.

3. Tap the drop-down arrow next to the Offset Point button and tap Set Reference Point A.
4. Tap the screen to set reference point A.
5. Tap the drop-down arrow next to the Offset Point button and tap Set Reference Point B.
6. Tap the screen to set reference point B.
   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.

7. If you have a rangefinder activated, shoot your target from each reference point or simply tap the screen at the location of your feature.

   The Point/Vertex dialog box opens on the 2 Point Offset page.

   Note:

   Refer to section, Using your rangefinder for information on how to use your rangefinder with ArcPad.

8. Make any necessary changes to the information that is displayed.

   If you are using a rangefinder without a compass, you will need to specify whether the point you are capturing is to the left or to the right of an imaginary line between reference points A and B. You will also need to shoot a measurement twice, once for each distance from each reference point.

   If you are only using a compass, you will be using two bearing measurements to calculate the offset.

9. Tap OK.

   The Feature Properties dialog box is displayed with an edit form, if it exists. Enter the information for the new feature.

10. Tap OK.
11. Your new feature is created.
