App for entering heading and distance information from a platt map

“I want to find and map my property lines, I have 16 acres of woods and wetlands. I have located one survey marker and I have a platt map of my property with headings and distance to the next corner. Which one of your products would let me create a waypoint at the survey marker to use as the starting point and then enter the rest of the heading and distance information so that I can walk and mark my property lines and corners?”

The Deed Calls & Stakeout app will let you stand at the survey marker and get the GPS coordinates of that point as the starting point for entering the deed plot information (bearing and distance). If your deed document uses magnetic north, then you should enter the declination angle for your location into the Orientation field in the app. Then you can use the Line Stakeout function in the app to help you walk and physically mark your property lines and corners. This app works on iPhone and iPad devices.

Keep in mind, though, that the accuracy of your work depends on the GPS receiver used, and the built-in GPS receiver of the iPhone and iPad devices is not that accurate. Some of our app users use a compatible external GPS receiver, such as the Dual XGPS-150A or the Bad Elf GPS, to get 2 – 5 m accuracy. GPS receivers with sub-meter precision, such as the iSXBlue II and EOS Arrow, cost a great deal more.

What are the coordinates of the point of beginning?

“The reference point for finding my ‘point of beginning’ is the SE corner of a section. Because of the difficult terrain, it would be very difficult for me to physically go to that spot. My property description states . . . What I think this means is that property corner #1 is 2,654 and 7/10ths feet from the SE Corner of the Section along a line that runs about 7 degrees north of west from that corner.”

Your property description references a corner of a Section in a Township and Range. You can get the coordinates of that corner by using the tool at the following link:
http://www.earthpoint.us/townshipssearchbydescription.aspx

Enter the State, Section, Township and Range data then click the View button. The LAT-LON are given in the Degrees unit. A 35 for the latitude should be entered as 35N, and a -95 for the longitude should be entered as 95W.

Once you have the coordinates of the reference corner, and you know the position of your point of beginning relative to that corner, you could set the reference corner as the First Node on the Feature Info page of the Deed Calls & Stakeout app. In the Calls page enter the angle and distance to your actual Point of Beginning (POB). Then enter a couple random segments with non-zero direction so as to form an area plot. Here, we are just after the location of your POB; the other segments don’t matter in this step.

After the bogus deed plot has been created, you can use the Pick button on the Feature Info page to pick your POB as the First Node. Write down the displayed coordinates.

Go to the “Calls” page and delete the unwanted calls.
Go back to the “Feature Info” page and enter the POB coordinates.
Then you can start entering the actual deed calls.

Your deed probably references magnetic north. You will need to find out the magnetic declination for your location to enter into the Orientation field.

Is there not an Auto-close in Deed Calls – Grid – Stakeout?

In addition to the Create Deed Calls function, the Deed Calls – Grid – Stakeout app provides the ability to add Points, Lines and Areas to your job map by manual digitization.

Before entering the deed calls, you can specify whether they are for creating a Line Feature or an Area Feature. After entering the deed calls, you can convert the deed plot to a Feature, and an Area type Feature will automatically close.

With an Area Feature created in the job map, you will be able to create grid points over the Area Feature. You will also be able to stake out the boundary of the Area Feature.
