I was wondering if it is possible to use the gps receiver built in to an iPad with the iCMTGIS Pro program?

Yes, you can use the GPS receiver built into an iPad with the iCMTGIS PRO app. Please keep in mind that the built-in GPS receiver of the iPad is not quite accurate. If you just want to record a rough position or to have the app lead you to the vicinity of a location to find a stake, that is fine. In that case, you could just as well use a lower-priced app like the iCMTGIS III.

iCMTGIS PRO distinguishes itself by being able to interface directly with a couple compatible high-precision external GPS receivers to obtain accurate results. Some of our customers are using such a system in their RTK GPS applications.

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.

Map in Bluff City TN area as displayed in the Deed Calls Pro app

After updating Deed Calls Pro to version 1.0.6 on his iPad Pro running iOS 11, a user wrote:

“A quick browse thru the job list and all looks well. I’ll do an edit on this job to make sure but I suspect it is functioning properly.

This is the Bluff City Tn. area along the Holston River 1775-1782. It was the frontier of Revolutionary War America. My 4th and 5th grandfathers and uncles owned a 5 of these plots. Thanks to you guys I got to walk in the steps last year. I got to stand on the river side and know those men had walked that same path 100 times. It was one of the great times of my life and couldn’t have done it without you guys. Maybe my grandkids will do the same one day. It’s more than an app. . . . . . This is only one of the Jobs. In other Jobs I’ve plotted the north side of the river to just south of Bristol and to the south as far as the Watagua River.”

iOS 11 compatibility and saving data files

“I have received a msg pop up on Deed Calls Pro that says it will no longer work with iOS 11. There are no updates. How will I be able to protect and save my 200 plots? Are you working on a solution? Time is very short.”

We have recompiled a number of our apps (including the Deed Calls Pro) to work with the 64-bit architecture. Please check for the app update at the App Store.

To save your data files to your PC or Mac, first connect your iPad Pro to your PC or Mac via iTunes. In iTunes select your iPad Pro device then go to the File Sharing section. Please see the file transfer details at the following link:

Copy ALL the files to your PC or Mac.

After the iOS 11 and app update, connect your iPad Pro to your PC or Mac via iTunes and copy the files from your PC or Mac to the Deed Calls Pro app.

Some GPS/GNSS receivers compatible with iPad and iPhone devices

Recently Geneq Inc. announced their new SXBlue Platinum GNSS receiver.

As you know, the accuracy of the work performed using an iOS GPS/GIS app depends on the GPS receiver used. The assisted GPS provided by the iOS devices are not adequate for serious work that are based on accurate locations. External GPS receivers with much better precision abound, but only a limited number of them are compatible with the iOS devices. Following are links to information on some of the external Bluetooth GPS/GNSS receivers that can work with iPad and iPhone devices. Not sureprisingly, higher precision equates to a higher price tag.

Question about the GPS marker

“I also use the program to locate plots to take sample points. With the current cursor on the program you cannot see the points on the background map. Is it possible to change the cursor to be transparent or a cross hair to see the points on the map?”

The GPS marker in the iCMTGIS-series apps serves a few purposes. When GPS is turned on, it indicates your position. If you walk at a brisk pace, the arrow inside the circle will point in the direction you are walking. The arrow in the GPS marker will be a gray color when your speed is very slow (e.g. less than 1 m/s). The arrow will change to a red color when your speed is above 1 m/s. The direction of the arrow indicates your current direction. There is not a way to change this marker symbol.

You could try zooming into the map and enlarging the point symbol size. The GPS marker will stay the same size and will therefore become smaller compared to the background elements.
