Using Deed Calls & Stakeout to locate property corners

“I had a topography company locate the northern two corner stakes for my trapezoidal property. I am trying to locate the southern two. I purchased your product Deed Calls and Stakes for my iPhone 7. My hope was that I could go to the North east stake, have your app acquire the GPS coordinates of the stake and then move to the North West stake and do the same. From that I would like to walk down the fence line and have your app tell me when I am 1440’ from that stake… should be right at the South West stake. . . . I don’t have typical x Deg N, y Deg E coordinates.”

Normally, you would get the first node position then use the deed document and enter the deed calls to plot out the property boundary. Then you would use the Line Stakeout function to help you walk along the boundary. The Line Stakeout will show you your Station value. The default Station value at the beginning point is 0′. Therefore, the Station value would be the distance you have walked.

It sounds like you have a fence to follow all the way to the southern two stakes from the northern two corners. This means you could use the Point Stakeout function to help you determine when you are a specific distance from, say, the northwest stake. You could try the following steps, but keep in mind the accuracy of your work will depend on the GPS receiver you use. The GPS on the iPhone is not that accurate. Many users use an external Bluetooth GPS receiver to obtain better accuracy. High-accuracy receivers have a high price tag. Hopefully there are markers at the southern two corners to help you confirm the location when you get to the vicinity.

I. Create a node then use Point Stakeout

1. Turn GPS on and wait a few minutes. Walk to the Northwest corner.

2. Follow the instructions under Open a Deed Calls File in the Help document to create a Job.

3. Follow the instructions under Set First Node and Symbolism and use Pick GPS to get a node at your position.

4. Tap the Line tab then tap the Calls button.

5. Tap the Add button to add a line. Accept the displayed values by tapping on the Back button. When app displays “Update Feature?”, tap on Yes. Now you have created 2 nodes. The one at the GPS marker is the Northwestern corner.

6. Follow the instructions under Point Stakeout. For the Target Feature select the Line you have created. The node you are interested in is Node 1. Now when you walk away from that position, you will see the separation distance displayed in the Range field.

7. Walk along the fence southward and stop when Range shows the target distance. Tap the Store Stake Point icon to store this point.

II. Use Line Stakeout

As the partial map you provided shows S83-53-00E 645.50′ for the southern border, you can use the Deed Calls function to create a Line that represents this southern border.

1. Go back to the Deed Calls screen and change the First Node location by tapping the Pick button then tapping on the Point that you have created at the southwest corner.

2. On the Calls page, tap the Edit button then enter the bearing and distance information:

Horizontal Angle: S83-53-00E

Horizontal Distance: 645.50

3. Tap the Back button and confirm to update the Feature.

4. Now you can follow the instructions under Line Stakeout to move along this line to get to the Southeastern corner and store the stake point.

  1. I purchased the Deed and calls app for iphone/ipad so I can locate the corner pins on a 20 acre plot.I have downloaded the coordinates of the lot corners from our local city map which provides both lat and long as well as 10 utm decimal.I linked using the Dual gpsx 150 and registered =/- 3 meters.I know of one benchmark/stake , how do I set the waypoints and walk to the other 3 corners?

      Hello Mark,

      Did you get the Deed Calls & Stakeout app or just the Deed Calls app?

      Deed Calls & Stakeout app will let you enter the coordinates of the point of beginning (your bench mark stake) then enter the plot description (for example, Northeast 30 deg 100ft ). After completing the deed plot, you can select it as the target for Point Stakeout or Line Stakeout to walk to the other 3 corners.

      If all you have are the coordinates for the 4 corners and no deed description, then you can use the “Locate point by address” function of the Stakeout iCMT app to enter the coordinates and store them as points. Then you can use the Point Stakeout function to go to each point.
