iCMTGIS PRO for electric pole staking

“So what I’m needing is software that can collect a start and end point for a new line and then take those and tell me where along that line to set my electric poles in order to keep them nice and straight in line with the starting and ending pole. Also it would need to be able to route me say 90 degrees from one point across the road to another pole 65 feet away (for example). Then if I could take these points and load them into Arc GIS as points to snap to, where I could then use my staking application to draw the new lines on the map at these points.”

Yes, iCMTGIS PRO along with the EOS Sub-cm GPS receiver will enable you to achieve what you have in mind.

1. Data Collection

You can use the GPS – Collect function in iCMTGIS PRO to record the start and end points then create the Line Feature.

2. Line Stakeout

The GPS – Line Stakeout function in iCMTGIS PRO will help you stay on the straight line and display your distance from the starting point. This will allow you to set a pole at a specific distance from the staring point. The app also provides a function to let you store the position of the pole. There is a tolerance setting in the Stakeout function that will issue beeps and flash a “Target” message as long as you are within range.

3. Traverse and Point Stakeout

“Also it would need to be able to route me say 90 degrees from one point across the road to another pole 65 feet away (for example).”

The GPS – Collect – Traverse function in iCMTGIS PRO will let you occupy an existing point and create a new point based on distance and angle (bearing or azimuth). Then you can use the GPS – Point Stakeout function to help you get to the new point.

If that “other pole” already exists as an imported point, then you will simply use GPS – Point Stakeout to get to it.

In fact, I would incorporate the point representing that other pole or any other location in the Line Feature mentioned in Step 2 above. In other words, you would create your entire “route” as a single Line Feature (no matter how many bends there are) then use the Line Stakeout function throughout.

4. Digitization

You can draw Points, Lines and Areas within iCMTGIS PRO. You can export these Features to Shapefiles to use in other apps. You can also import Points, Lines and Areas from Shapefiles.

“Would one of your less expensive apps do some of the tasks I talked about in my first email just to try it out?”

The Stakeout iCMT app is very cost effective for performing the point and line stakeout tasks. What it does not provide, among others, are the GPS – Collect function and the GPS – Traverse function. In addition, it gets the GPS position from the Apple CoreLocation, which is not as accurate as the GPS position that iCMTGIS PRO gets directly from the EOS GPS receiver in the “Enable External GPS receiver” mode.

The Stakeout iCMT app will be great to use for a practice run of your stakeout operation or for training your employees.

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.

How to use iCMTGIS PRO to extend a line beyond its end points?

“I have managed to join two nodes and get a straight shape line between them, but how do I do to extend the line on the outside of the nodes?”

There are a few ways to achieve this. Here is a quick way (but not precise): Tap on the existing straight line then select the Insert Node function on the Tools menu. Move the circular Node Tool to the end point of the existing straight line. Tap in the center of the Node Tool. Select “After” then tap on Next step. Now move the Node Tool to a new position, eyeballing the proper bearing, then tap in the center of the Node tool to add the new node. To extend the line in the other direction, select the start point of the line and select “Before” for inserting the new node.

A precise way is as follows: After you have created the initial line based on two existing points, tap on it then select View Deed Calls. Tap on the Calls tab then tap on Edit.

Increase the horizontal distance then tap the Back button.

Confirm to update the Feature. You will see that the Line Feature has been extended in one direction.

Now use the end nodes of the elongated line to create another line in the opposite direction. It will have a different Line ID. You can turn on Sheet View to see the two line records. Select the new line and use the View Deed Calls function to change the distance value. Confirm to update the Feature.

If you don’t confirm to update the Feature, then no change will be made to the original line.

I would create a new Topic (named “Long Line”, for example) into which to put the final long line. This will help reduce confusion when you are staking out in the field. Have this new Topic active and select the correct line when you are doing the Line Stakeout. (You could also delete all the other lines that you will not be using for stakeout.)

 

Does the deed call and stakeout app have all the features of both applications?

The Deed Calls & Stakeout app will let you enter deed calls to draw a deed plot. Then you could use the Point Stakeout function to help to get to any node on the boundary of the deed plot. Or, you could use the Line Stakeout function to help you stay close to the boundary line while walking around the property.

The Deed Calls & Stakeout app only works with the nodes in a deed plot.

On the other hand, the Stakeout iCMT app will let you add Points, Lines and Areas manually or import them from Shapefiles.

 

Staking out contour lines

“i am looking for an app that will allow me to find and walk a contour line so i can mark it. Will the coconut – volume-stakeout app be the one i need?”

Do you have the contour lines as Shapefiles? If so, you can import them into the Stakeout iCMT app. Then you could select one of the contour lines and use the Line Stakeout function to walk and mark the contour line.

The Contour – Volume – Stakeout app provides the stakeout functions as well as the ability to create the contour lines for an area if you have the elevation data for many points scattered throughout the area. It does not appear this applies in your case.

Please note that the accuracy of your work will depend on the GPS receiver used. If you require good accuracy, then you will need to get a high-precision GPS receiver (such as the iSXBlue II or an EOS Arrow) to do the stakeout.

Also, please keep in mind that a set of Shapefiles containing too many contour lines can overload the system memory of your device.

GPS/GIS apps that will also draw a deed plot

“I have Deed Calls & Stakeout for iPad and have successfully created a plat with property lines. I have walked my property and found the corners. It’s a really great app. What I’d like to do next is walk my property and draw features such as tree lines, roads/paths, rock outcroppings, springs, etc. How do I do that?”

The Deed Calls & Stakeout app was designed to help you create a plat by entering the deed calls then walk the property line. It does not provide the functions for digitizing Features such as tree lines, roads/paths, houses, etc.

The Deed Calls Pro app for iPad has the deed calls functionality as well as the digitizing functions. This app can convert a deed plot that you have entered into a Feature. This will allow you to draw a deed plot, save it as a Feature then draw another deed plot. You will also be able to manually drop GPS points or draw lines and areas in this app and assign different symbols/colors to the Features that represent roads, houses, trees, springs, etc.

If you wish to use GPS to map Point, Line and Area Features to represent tree lines, houses, etc., these tasks are better performed using one of our GPS/GIS data collection apps, such as Forester GPS GIS II, Forester GPSGIS III, iCMTGIS III or iCMTGIS PRO. These apps will let you record many GPS fixes at one location and average the data to obtain a more accurate position record. Thy also provide the ability to create a deed plot and convert it to a Feature.

App for entering heading and distance information from a platt map

“I want to find and map my property lines, I have 16 acres of woods and wetlands. I have located one survey marker and I have a platt map of my property with headings and distance to the next corner. Which one of your products would let me create a waypoint at the survey marker to use as the starting point and then enter the rest of the heading and distance information so that I can walk and mark my property lines and corners?”

The Deed Calls & Stakeout app will let you stand at the survey marker and get the GPS coordinates of that point as the starting point for entering the deed plot information (bearing and distance). If your deed document uses magnetic north, then you should enter the declination angle for your location into the Orientation field in the app. Then you can use the Line Stakeout function in the app to help you walk and physically mark your property lines and corners. This app works on iPhone and iPad devices.

Keep in mind, though, that the accuracy of your work depends on the GPS receiver used, and the built-in GPS receiver of the iPhone and iPad devices is not that accurate. Some of our app users use a compatible external GPS receiver, such as the Dual XGPS-150A or the Bad Elf GPS, to get 2 – 5 m accuracy. GPS receivers with sub-meter precision, such as the iSXBlue II and EOS Arrow, cost a great deal more.
