Stake out nodes

To use the eCompass for stakeout, the eCompass must be calibrated. To calibrate the eCompass using Google Maps, go to https://support.google.com/maps/answer/6145351?hl=en.

You must complete a calibration before you compute offset or intersection points, or stake out points. If you change the calibration after computing or staking out these points, they will not be consistent with the new coordinate system and any points computed or staked out after the change. For more information, see Site calibration.

  1. Tap .

  2. Tap to start the GNSS method.

    The software connects to the GNSS receiver and a green badge on the GNSS method icon confirms that enough satellites are being used for Penmap to calculate a position.

  3. Tap Stake point and then tap the node to stake out.

    The eCompass starts, showing the bearing and distance to the selected node.

  4. Start walking toward the node. As you move, the map moves to keep the selected node in the center of the map.

    When you are within 1 meter of the target, the eCompass changes to closeup mode. See Project settings.

  5. When you reach the target, check the stakeout deltas. When GNSS observations are within the configured stakeout tolerances, the horizontal precision icon and the vertical precision bar in the map turn green.
  6. Mark the point on the ground that corresponds to the node in the map.
  7. If required, measure the node using the appropriate survey method.
