What to do when deed description does not provide bearing information


A Deed Calls & Stakeout user is baffled by an old property description that refers to a stretch of a certain road and specifies internal angles instead of bearings. He is able to stand at the point of beginning and obtain the approximate GPS coordinates for it.

Applying the Measure Distance function on the displayed Map, we were able to get the approximate bearing of the road segment. Then calculating the bearings for the remaining calls becomes an exercise in geometry and Deg-Min-Sec angle arithmetic operations. The bearing of each leg will need to be computed by using the bearing of the previous leg and the internal angle provided in the deed description. One will need to keep in mind that there are 60 minutes in a degree and 60 seconds in a minute.

As the bearing of the first leg determined by Measure Distance refers to true north, you can set the value of the Orientation field to 0.

The resulting deed plot can only be used as a rough reference as there are several sources of error:

1) The point of beginning may be at the wrong location as the user may not have used a high-precision GPS receiver to record the position.

2) The bearing of the road segment obtained from Measure Distance may be slightly off.

3) The printed value for one of the angles is partially illegible.

4) There may be some error in the old survey data, resulting in a closure error of about 11 ft.

Using the Measure Area tool, we see that the area comes close to the published value.

Using independent GPS to re-position a deed plot

“Can I create a deed plot using metes and bounds information then use a separate accurate GPS receiver to get the coordinates of the initial point to re-position the deed plot?”

Yes. As long as you can get the LAT-LON coordinates of the initial node, you can enter them into the Create Deed Calls routine, and the existing deed plot will be moved to the correct location. You will also be able to enter an orientation angle to help line up the deed plot with the roads on the displayed Apple Map. Such capabilities are provided by the following apps: Deed Calls – Area – Perimeter, Deed Calls & Stakeout, Deed Calls – Grid – Stakeout, Deed Calls Pro, Farming GPS GIS, Farming GPS GIS II, and Forester GPS GIS.

With respect to staking out the boundary of the plot, please note that, if the external GPS is one that does not interface directly with the iPad, iPhone or iPod touch, the Stakeout functions in the Deed Calls & Stakeout app will not be able to use it to help guide you to a target location. It will be tedious for you to try to manually match the position displayed by the separate external GPS to the coordinates of the target location.

Our deed calls apps can export the deed plot to a PDF file. However, the Apple Map in the background cannot be exported to PDF. The Deed Calls Pro, Farming GPS GIS, Farming GPS GIS II, and Forester GPS GIS apps are able to load a .pim background map and export it along with the deed plot to a PDF file. To make use of this capability, you will need to purchase the PC-GIS PRO software to prepare the .pim background map, which you will transfer to your device. The .pim background maps can be used off-line (no wi-fi required).

Deed Calls & Stakeout updated to 1.0.2

The Deed Calls & Stakeout app has been updated to version 1.0.2. The changes are:

1. Reinstated the Varas and US Survey Furlongs distance units.
2. Fixed a bug in displaying the Station value when the starting station value is not zero.
3. Disabled map tilt in the Show Standard mode.

Mix work with pleasure using the newly released Deed Calls & Stakeout app

As many users find the stakeout functions helpful, we are now providing the Deed Calls & Stakeout app, which will enable you to stakeout the deed plot you have created using the Deed Calls functions. This app will work on your iPhone, iPad (with GPS) or iPod touch (with GPS).

This app will let you enter distances and angles from your deed to create a boundary plot. You may also enter an orientation angle for the deed plot.

The Point Stakeout function will help you locate and stake the individual nodes on the deed plot. The Line Stakeout function will guide you along the outline of the deed plot.

The Deed Calls & Stakeout app also provides the Measure Distance and Measure Area functions as well as the ability to export the deed plot and deed calls to a PDF file. You can export the deed shape to a DXF file. You can email the PDF files, job (*.dcf) files and the DXF files.

In addition, you will be able to view a PDF file from within the Deed Calls & Stakeout app by marking the View (on iPhone) or View File (on iPad) checkbox in the PDF Export File Dialog screen. You will be able to view not only a deed plot file you have saved but also view any PDF file you have copied into the Documents folder of this app.

And, of course, if you are into geo-caching, you could use the Stakeout functions to help you get to the caches and find the treasures. The article at this link points you to a couple attractions in the UK.

The Deed Calls & Stakeout app is now available at the Apple App Store.

Deed Calls – Area – Perimeter app now available

The Deed Calls – Area – Perimeter app is now available at the Apple iTunes store. This is a universal app that will work with iPAD, iPhone and iPod touch.

This app will let you enter angles and distances and display the resultant boundary plot. It will label each line segment with its length and bearing (or azimuth). It will also label the arc segments with the relevant parameters. The Summary screen will display the completed figure, its area, its perimeter, as well as the closure error. If you are unsure about the last line segment, you may choose the Auto-close option and have the figure closed automatically.

If your device is equipped with GPS, you may pick the GPS position as the point of beginning. You may also enter the actual coordinates of the initial node. In these cases, the app can display the deed plot on top of the built-in Map. If you just want to get a quick plot and don’t care about the location of the property, you could start the plot from any random spot.

You can obtain a PDF report containing the map drawing and the deed calls data. You may also save the Deed Calls File (*.dcf) and send it out via email. A friend in need is a friend indeed. The easy-to-use Deed Calls – Area -Perimeter app might just become your friend in “deed”.
