What to do when GPS signals are blocked by heavy canopy?

“I am currently using the program to plot a property line for our vineyard. One of the corners of the property is tucked deep within some woods where satellite reception is poor. Therefore, the program is not allowing me to record the point. Is there any way to work around this? Perhaps increase the rms limit to within several feet so as to allow for data collection? Thanks for the help.”

This is why iCMTGIS PRO provides the Traverse function to deal with a situation where GPS signals are blocked by heavy canopy. How far is this corner away from a point at which you have good satellite signal reception? What you could do is to record a good point at the periphery of the wooded area then measure the distance and bearing from this point to that corner. Then you will use the Traverse function under GPS – Collect data to specify the GPS point as the starting point and enter the distance and azimuth or bearing information to create the corner point.

You could try and see if you could record the point by relaxing the RMS limit and the DOPS limit, but the position accuracy will be compromised.

If the accuracy requirement of this point is not strict, and you are able to identify the location of this corner on a background map, you could digitize it by using the Add Point Manually function. Zoom in to better place the point.

If you have a deed document including the property description (distances and directions around the perimeter), you could use the Deed Calls function to enter such information in iCMTGIS PRO to draw all or part of the property boundary as a reference for digitizing the corner point.

After you have created the corner point, you can add it to the remainder of the GPS’d property boundary Area by using the Insert Node function.

Plotting multiple deeds

“I have the Deed Calls Pro App for the Apple ipad. Is it possible to plot multiple deeds and place them adjacently next to each other? I am having trouble determining how create a new deed while still viewing a previous deed description. “

With Deed Calls Pro you can create multiple Features that represent the deed plots.  The Created Deed Calls function will create one single deed plot at a time. You can save the deed description in a file using a unique file name.

When you exit the function, the app will ask you if you wish to create a Feature. Answer “Yes”. Then an Area Feature will be created.
Tap on the Area Feature then tap on the Feature Properties icon.
Mark the Show Segment label check box to display the angles and distances.

Now, do not have any Area or Line Feature highlighted on the map.
Select Create Deed Calls to enter the First Node and deed calls for your next property. When you turn on the Snap to Node icon, you can pick an existing corner as the First Node. You can enter the deed call for a line segments that is shared by two properties.
When done entering the calls, again confirm to create the Area Feature then have the segment labels displayed.

This functionality is also provided by iCMTGIS III, Forester GPS GIS II/III and Farming GPS GIS II/III.

Deed Calls – Grid – Stakeout updated for iOS 8 compatibility

Deed Calls – Grid – Stakeout Version 1.0.1 has been released.
This update fixes the iOS 8 compatibility issue.

Deed Calls – Grid – Stakeout app for iPad and iPhone released

DeedCallsArc

Some iPhone users do not need all the functions provided by the Farming GPS GIS or the Forester GPS GIS apps for iPad, but are mainly interested in generating a stand boundary based on deed calls, creating a sampling grid and then locating the sampling points.

We are pleased to announce the release of Deed Calls – Grid – Stakeout 1.0.0 app, which fulfills this request.

As the name indicates, Deed Calls – Grid – Stakeout provides the ability to enter deed calls to create a deed plot. A deed plot of Area Type can be converted into an Area Feature, over which you can create grid points or grid lines. Then you can use the Point Stakeout function to help you approach each grid point. Or, you can use the Line Stakeout function to help you walk the boundary of the land plot.

A preview of the Deed Calls – Grid – Stakeout app is available at the App Store.

Deed Calls Pro 1.0.3 update

The Deed Calls Pro app for iPad has been updated with the following changes:

1. The deed plot area will be filled with the specified area pattern when the closing error is less than 1 meter.

2. The issue reported by a user that Auto-close did not work properly with non-zero Orientation has been fixed.

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.
