Entering the metes and bounds description into the Deed Calls & Stakeout app

“The metes and bounds description of the property is over a page long. Is it possible to download the document to the app to avoid having to enter the information by hand?”

You will need to “translate” the property description into angles and distances. Then you can input the calls into the Deed Calls & Stakeout app.

Deed Calls & Stakeout are able to open a text file containing the calls in the proper format. The text file name needs to have the extension .dcf. An example of a .dcf file follows:

iPhone app for locating fence line and property boundary

“I have a ranch in Colorado that is relatively isolated. When at the ranch, I do not have internet or phone service. The property has metes and bounds descriptions for the boundaries. I am interested in acquiring your software application to confirm the location of fences and the property lines. Will this app function on my iPhone without internet access? Will the Deed Calls and Stakeout App perform the functions that I need to identify boundaries?”

You do not need Internet access for our apps or the GPS on your iPhone to work.

The Apple Map does need Internet access to be refreshed. However, you could load the Apple Map while you are at your office and cache it for use on site.

Some of our apps, such as the iCMTGIS III and iCMTGIS PRO, will let you load a GeoTiff map to use as an off-line Background Map.

The Deed Calls & Stakeout app will let you input the metes and bounds descriptions to draw the boundaries. For the boundary to be correctly placed on the map, you will need to provide an initial position and the your local magnetic declination angle.

Then, you can select the boundary and use the Line Stakeout function to help you walk along the boundary to confirm its location.

Please be aware that the iPhone GPS is not very accurate. An external GPS receiver such as the Dual XGPS-150A or a Bad Elf GPS can get 2-5 m accuracy. There are also expensive external GPS receivers that can provide sub-meter or even cm-level accuracy.

Is iCMTGIS PRO app a one-time purchase?

“If we by the app, is it a one time buy? What happens if the account is lost with the employee? Can we transfer to a different iPad?”

The purchase of any of our apps is a one-time software license purchase. You will want to purchase it using your company’s Apple ID. Any iPad or iPhone using the same Apple ID can download the app to use.

Websites for some GPS receivers compatible with CMT iOS apps

Our iOS apps can work with any GPS receiver that is compatible with the Apple iPad and iPhone devices.

At the following three websites, you can find GIS-grade GPS receivers that claim 2 – 5 m accuracy:

https://gps.dualav.com/explore-by-product?category=GPS

https://bad-elf.com/pages/products

https://buy.garmin.com/en-US/US/p/645104

The Trimble R1 boasts 50 cm max. precision.

EOS and Geneq Inc. provide high-precision GNSS receivers.

Many of our customers are using the EOS Arrows series GNSS receivers with our iOS apps. In particular, iCMTGIS PRO can directly interface with the Arrow GNSS to obtain more accurate position data.

The SXBlue Platinum GNSS receivers from Geneq Inc. also work well with our iOS apps, and can directly interface with iCMTGIS PRO. Their SXPAD & SXPRO mobile data collectors can run our Windows Mobile 6.5 and WEHH Windows Embedded Handheld 6.5 compatible GPS/GIS data collection software programs.

Does Farming GPS GIS III need wifi or cell service?

“Will this app allow me to plot a lines in my field and then allow me to follow them with a sprayer manually? Does It work without wifi or does it need cell service?”

Farming GPS GIS III provides the functionality for you to digitize Points, Lines and Areas over a displayed map. It also provides the Line Stakeout function to help you stay on the line while spraying.

Our apps do not need cell service.

The Apple Map that the Farming GPS GIS III uses needs wifi to load. You can load it at the office then use it in the field where there is no wifi as long as you do not close the map in the app.

Farming GPS GIS III will let you load a geotiff map (*.tif) to use in the background. Such off-line maps do not need wifi.

The accuracy of your work will depend on the GPS used. Many users get an external GPS receiver to use with their iPad devices. GIS grade GPS receivers claim 2-5 meter accuracy. High-precision GPS receivers are quite costly, but they can get down to sub-meter or cm-level accuracy.

GPS week rollover in 2019

It’s been 19.7 years since the last GPS week rollover took place in the year 1999. If you are still using an old GPS receiver for data collection, then after April 6, 2019 the GPS data will be recorded with a much earlier date. Newer GPS/GNSS use 13 bits instead of 10 bits to encode the GPS week value, and therefore will continue to work properly for a much longer time before the GPS week will be rolled back again.

According to EOS CTO Jean-yves Lauture, “GPS Week Number Rollovers have been accounted for and implemented in all Arrow firmware builds available from Eos since the creation of the Arrow Series™ product line.”

According to Donnay Fleury Nahimana, PhD, GNSS Development and Test Specialist, the SXblue devices of Geneq Inc. will continue to function properly after the 6th of April 2019 GPS rollover. The units are running GNSS firmware that accounts for the GPS rollovers on 13 bits since 1999.

According to John McLellan, C.H.ElF (Chief Helper Elf), Bad Elf, LLC, “I’ve been reassured by our engineers that rollover week is handled on all of our devices.” (4/7/19 update: We used our Bad Elf GPS-2200 to record a couple GPS points today. The date recorded is correct.”

According to the Dual Tech Support Team, “XGPS150 units that were manufactured before December 2011 will be affected by the rollover event. There will be a firmware version that will resolve this issue.” (4/6/19 update: We used our Dual XGPS-150A to record a couple GPS points today. The date recorded is correct.”

Video tutorials for apps

“Now I just need some tutorials on basic use. Is the help document pretty detailed, or would it be easier to use videos (which I generally prefer if available)? “

We have a couple tutorials listed at the bottom on the right side of our blog page.

You could get started with these two videos:

The Help document is quite detailed. Please read the section on Feature List.
