Using iCMTGIS PRO to work out land boundaries in Swedish forests

One of our customers, Håkan Bergstedt, wrote an article about using iCMTGIS PRO in conjunction with an EOS Arrow 100 GPS receiver to determine land boundaries in the forests of Sweden.

This interesting story was published on pages 28 and 30 of the March/April 2018 issue of the Geoconnexion International Magazine. You can view this article online for free before the May/June issue is released:

Stakeout iCMT for trailblazing

“I’m wondering if your software has the capability to allow a user to navigate to a location based on a set of coordinates. . . . The problem is that ArcPad is not designed to allow users to navigate to a set of points and I cant find anything else that will easily allow a user to do this, either. Through internet research, I discovered a reference to your iPhone app Stakeout iCMT. Before I recommend a purchase for this, could you tell me some more about the product? Will it show the tractor driver the location of the next point in our shapefile so that he would see distance and direction to get within 10-15 feet of that point? Please note the driver will NOT have to collect any data in the field he is merely using the program to show him how to drive the tractor in order to create a walking trail (which is NOT a straight line) through dense terrain.”

Stakeout iCMT will allow a user to navigate to a location based on a set of coordinates. It can also help the user to stay on course on a design line.

Stakeout iCMT can be used on an iPhone or an iPad. The iOS devices do not provide good GPS accuracies. You could use an external Bluetooth GPS receiver that is compatible with iPhone or iPad, such as a Bad Elf GPS or a Dual XGPS-150A, which claim 1-3 meters accuracy. There are more accurate GPS receivers available, which cost much more.

Stakeout iCMT is probably the least expensive but really powerful software solution for your task at hand. You can import your Shapefiles then use Stakeout iCMT in one of the following ways:

1. If you want the driver to go from one design point to the next, then create a Line Feature by using Add Line Manually and snapping to the points in the desired order. Then use Line Stakeout to go from one node to the next on the line shape.
You can set the distance tolerance for the app to notify you when you get within that distance from the current target point.

2. You could import the Line shape for the desired path through the woods. Then you would use the Line Stakeout function and let the app help you stay close to the line all the time. The Line Stakeout function will display your distance to the line all the time. And if you set a distance tolerance, then the app can keep on beeping as long as you are within the tolerance distance from the line.

We also have several other apps that incorporate the Stakeout functions along with other functionality.

I have never heard beeping from the app upon connection or during stake out.

Are you able to hear any sound from your iPad (outside of iCMTGIS III)?

If not, please check the Settings on your iPad.
Under Settings/General, there is an option for USE SIDE SWITCH TO:
If you have “Mute” checked, then please slide the side switch to the other position to undo the muting.

If you are able to hear sounds in general but just not the GPS navigation, data collection or stakeout sounds in our app, please check the iCMTGIS III Setup/Navigation Settings screen and the Stakeout Setup screen, and make sure the following check boxes are marked:

Navigation Beep
Featuring Beep
Target Beep (used in conjunction with the stakeout Tolerance in the Stekeout Setup screen)

Buffer & Stakeout app released

Area5
We have just released Buffer & Stakeout 1.0.0 for the iPad, iPhone and iPod touch.
This app will let you digitize a Point, Line or Area Feature, view its position, length or area, and create one or more buffer zones around it. If you wish, you may create a buffer zone along just a part of a Line (e.g. road, river) or Area Feature (e.g. land plot, timber stand).

The Point Stakeout function provided by this app can help you approach a point or a node on the boundary of an Area Feature or Buffer zone. The Line Stakeout function can help guide you along a Line Feature or along the boundary of an Area Feature or Buffer zone. You can turn the navigation beeps on or off. You can also set up the app to display an alert message and/or sound alert beeps when you are within a specified distance from the target you are approaching.

You may specify the distance unit (metric or English) and choose between Azimuth and Bearing for displaying angles.

You will be able to work with multiple job files, and you will be able to export the Features and coordinates to a PDF file. This app will let you view the PDF file it has created and also any PDF file you have copied into the Documents folder of this app. It will also let you email the PDF files (*.pdf) and job file (*.pmp).

The Buffer & Stakeout app can be downloaded from the App Store on iTunes.

I want to keep my tractor in line and also record the track

You can use iCMTGIS II or iGPSGIS II in conjunction with Stakeout iCMT. iCMTGIS II and iGPSGIS II will record the GPS track in the background while you use the Stakeout iCMT to keep your tractor in line.

With your iPad and a reasonably accurate external GPS receiver, you will be able to use iCMTGIS II or iGPSGIS II to record the locations for points, lines and areas. You will be able to drive around a land plot and map the Area Feature for the land plot. You could record a tractor path as a Line Feature. Or, you could turn on the Tracklog and have the track automatically recorded as you move along.

Stakeout iCMT provides the Point Stakeout and Line Stakeout functions. The Line Stakeout function will show how much you deviate from a path. You can either digitize that path in Stakeout iCMT, or get a previously recorded Line Feature or Area Feature from iCMTGIS II or iGPSGIS II.

When you tap the Settings button in a stakeout screen, you will see the option to display a message and/or issue a beep when you are within the distance specified in the Tolerance field. Therefore, if you set this tolerance value to be 3 ft, then as long as you are within 3 ft of the line you will hear beeps or see a “Target!” message flash on the screen. When you are out of bounds, the beeps will stop and you won’t see the “Target!” message.

That said, the accuracy of the stakeout and the recorded track or Line Feature will depend on the accuracy of the GPS receiver used. For sub-meter accuracy, you will need to budget for a GPS receiver like the iSXBlue II.

Stakeout iCMT will help you stay in line

“I wondered if the tone can alert me when I am in line with that straight line.”

The Line Stakeout function provided by Stakeout iCMT, Farming GPS GIS and Forester GPS GIS will continually display the distance between you and your projected position on a Line Feature or the boundary of an Area Feature as you move parallel to or along the line.

When you tap the Settings button in a stakeout screen, you will see the options to display a message and/or issue a beep when you are within the distance specified in the Tolerance field. Therefore, if you set this tolerance value to be 1 ft, then as long as you are within 1 ft of the line you will hear beeps or see a “Target!” message flash on the screen. When you are out of bounds, the beeps will stop and you won’t see the “Target!” message.

Keep in mind, though, that the GPS built in the iPad is not that accurate. If you need accurate results, you should look into getting an accurate external GPS device that works with your iPhone, iPAD or iPod touch.
