Wetland – Stakeout app TestFlight version 10604 available now

We currently have a TestFlight version for the Wetland – Stakeout app available. If you or your colleagues are looking to try it out for a few weeks, please email your request to support@cmtinc.com.

When your email address has been added to the testers list for an iOS app, you will receive an invitation email from Apple.

Please open that email then tap on the link provided in that email to run the TestFlight app. Then you will see the icon for the app to be tested with an Install button by its side.

Tap on that Install button to install the app to be tested.

The Wetland – Stakeout app is mainly for recording observations at a site using the wetland delineation form templates. It provides the wetland delineation data entry/report forms for all the ten regions in the USA.

The app will let you import a plant list with the indicator status so it can automatically populate the Indicator field and user enters a Species name. You do not need to import the entire list for your Region, but can tailor the list for your local application. You can use Excel to help prepare your plant list.

It will also let you design your own data entry form.

The included Point Stakeout and Line Stakeout functions can help you get back to a previously surveyed area.

The position accuracy depends on the GPS receiver used. The accuracy of an Apple GPS is about 10 m. A GIS-grade external Bluetooth GPS, such as the Bad Elf GPS-2200 and the Dual XGPS-150A, can provide 2 – 5 m accuracy.

The app will let you export the completed form in PDF format. You can keep the Job file on the iPad for future editing. You will create a new Job file for each report form if you want to retain the Job data on the iPad. The Job files can be copied to your PC for safekeeping.

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.

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.

Question about Contour – Volume – Stakeout

“Does this app calculate the Contour and elevations based on Google satellite Aerials or do you need additional equipment in the field to be able to measure the different elevations?”

The Contour – Volume – Stakeout app will plot the contour based on the elevation data you enter or import. You will need to supply the elevation data.

Our iCMTGIS PRO app provides the GPS mapping and data collection functionality for recording 3D position data. You will need to use a compatible high-precision GPS receiver (such as the SXBlue Platinum or the EOS Arrow Gold) to obtain accurate results. iCMTGIS PRO also provides Contour-Volume functionality.

We do have software (e.g. PC-GPS 9, PC-MAPPER 9, CMT-Forester) for use on a Windows 7, 8 or 10 computer that will plot contours based on DEM (Digital Elevation Model) data provided by the NGS.

EOS Arrow 100 Case Study

If you missed Håkan Bergstedt’s article published in the March/April 2018 issue of the GeoConnexion International Magazine, here is the link to an in-depth write-up posted on the EOS website.

https://eos-gnss.com/mittnorr-land-boundaries/

When faced with the challenging task of finding survey markers or boundaries in an area overgrown with thickets, think iCMTGIS PRO and a high-precision GPS receiver such as the EOS Arrow 100.

Stakeout iCMT or iCMTGIS III, which one to get for placing moorings?

“We intend to use the Arrow to place moorings in our mooring grid… I was looking at iCMTGIS PRO, but thinking that is much more than what we need. I rather start with the simpler program if it will give us what we need, experiment with your apps before purchasing the more expensive one, if it even would make a difference.”

This customer is using the Stakeout iCMT. It looks like he will need to switch to iCMTGIS III because of the following reasons:

1) He needs the ability to import point data in GPX format.

2) He needs to have coordinates displayed in decimal degrees rather than in DMS.

3) He needs to work in the “moving map” mode, in which the background map will be rotated so that the boat always points to the top and then a compass is pointing the direction you have to go.

4) He wants the mooring points to be labeled with their names on the map.

5) He does not require land surveying accuracy.

Besides, iCMTGIS III also provides the ability to record Points, Lines and Areas using GPS, as well as the ability to create the mooring grid points over an area. It will not only let you work with latitude and longitudes, but also with State Plane, UTM and user-defined coordinate systems.

How to zoom in in Stakeout Mode?

“Wow, yes turning off map I can get more zoom. But how do I zoom when in stakeout mode? Or does that work with map off? I get that error sometimes still that says: ‘only point or line or area can be selected’, when I try to zoom.”

In Stakeout mode, the fields are waiting for your input. If the cursor is at the stakeout target field, a tap on the screen is interpreted as a Feature selection. When you want to work with the map (like zooming in or out), please remember to have the Cogo icon and the Apple Map turned off.

If you have a geotiff Background Map loaded (as in iCMTGIS III or iCMTGIS PRO), it does not affect the zoom.

First Node for the CMT Deed Calls function

“I entered in my lot information, and your app was accurate in the square footage to within less than an inch. However, the location on the map is off by several hundred feet.”

The deed plot in the Deed Calls & Stakeout is drawn based on the location of the First Node. Do you know the LAT LON of your point of beginning?

You could use the Pick GPS function to get a rough location, the accuracy of which is based on the GPS receiver used.

Please also read the following article at our blog site:

https://icmtgis.wordpress.com/2016/06/18/i-have-my-deed-with-the-property-description-but-i-am-not-sure-where-or-what-to-exactly-enter-into-deed-calls-stakeout/

After you have specified the correct location for the First Node, the entire deed plot will be moved to the correct location.

Another thing to note is the Orientation. If your deed calls are based on magnetic north, then please enter the magnetic declination for your location into the Orientation field.

“Thanks. I was out today and found one of the original corner marker iron pipes, so now I have the exact location to use as my first node.

I was amazed at the accuracy of your program. It had the square footage identical to the figure on a plat map to within 0.45 of a foot.

I am using it to find the property lines of out lot. We have been here 37 years and have a wooded lot, and I just want to be sure I know where the boundaries are. So now is the time to do this, before the brush grows.

I bought your App to do this as a surveyor wanted $3,500.00 to do it, even though I did not need a plat map submitted to the county.

Thanks again for the great support.”

Stake out using iPhone device

“I search application to stakout a polyline with my iphone. I see you make this for ipad but i don’t see for iphone.”

The Stakeout iCMT app can run on iPhone and iPad devices.

If your polyline is stored in a DXF file or as Shapefiles, you can import it into the “Stakeout iCMT” app and let the app help you stake it out.

The accuracy of your work depends on the GPS used. The iPhone GPS is not quite accurate. You can get a compatible external Bluetooth GPS (such as Dual XGPS-150A or Bad Elf GPS) to achieve about 2 – 5 m horizontal position accuracy. High-precision GPS receivers will cost a lot more than these GIS-grade GPS receiver.

iPhone app for mapping property lines

“I just purchased the Stakeout ICMT app for my iphone. . . . I thought this was the app that worked with your iPhone GPS to walk the property line. But from your email it sounds like there is another one. What is the app called? Is there any way I can get a refund for this app and purchase the other one?”

Stakeout iCMT can help you approach an existing Point or walk along an existing Line or Area Feature in the Job file. It assumes you can import or digitize the Features to get their coordinates.

You could, if you wish, use the Add Area Manually function in Stakeout iCMT and log nodes for an Area Feature by tapping the PickGPS button once every few seconds while walking your property boundary. However, this is not how GPS mapping is usually accomplished.

Our iGPSGIS II app for iPhone provides the GPS mapping capability. While you walk around the property, you can have the app automatically log a GPS node every second.

Please note that the accuracy of your work will depend on the precision of the GPS receiver you use. The built-in GPS in iPhone is not that great (unofficially, around 10 meters). Some of our customers use the Dual XGPS-150 or the Bad Elf GPS 2200 to get 2-5 meter horizontal accuracy.

As these apps are sold via Apple, please contact Apple App Store to inquire about switching out an app that you purchased recently.

iCMTGIS II, iCMTGIS III and iCMTGIS PRO comparison

“I’m hesitant to spend $300 for the pro app if the $95 or $200 apps will suffice but I’m having a difficult time finding a comparison of features among the apps.”

Built-in Attributes 512x384

The three apps in the iCMTGIS-series all provide real-time GPS/GIS data collection and mapping functions. They will let you add user-defined Attributes for the recorded Features either manually or via a Feature List (attribute table). They will let you import and export Shapefiles. The differences are in the additional functionality provided by the more expensive apps.

If you just need to use GPS to map Points, Lines and Areas and record their associated descriptions, iCMTGIS II will do. iCMTGIS II can display the built-in Apple Map as background. If you would like to use an off-line geo-referenced background image, you will need to first use the optional PC-GIS software to convert the GeoTiff, GeoJpeg, ECW or MRSID files to the .pim file format. The .pim map can work in the “moving map” navigation mode. (Many of our existing customers already have the PC mapping software.) iCMTGIS II only works on an iPad device. Its iPhone equivalent is the iGPSGIS II app.

iCMTGIS III and iCMTGIS PRO can run on iPad and iPhone devices. These two apps will let you load a GeoTiff image or a .pim image as background map. They also provide a built-in Attribute List from which you can choose as additional Attributes for the Features. One of the screen shots displayed here shows the current list of built-in Attributes that you may elect to include in the data records for the Features recorded using GPS. Other additional functions are also provided in these apps, which help you stake points/lines/areas, create Features by entering distances and bearings, as well as classify, sort or perform a search on the Features in a Topic layer, import and export Point Features via a text file, etc.

GPS surveying using iPhone

GPS surveying using iPhone

iCMTGIS PRO has all the functionality of iCMTGIS III plus the Contour/Volume and Create Buffer functions. What sets it apart from the other two apps is that it provides the ability to receive the NMEA message stream directly from a few specific external GPS receivers. When the “Enable the External GPS” option is selected, iCMTGIS PRO will get the GPS information directly from the external GPS receiver rather than the iOS CoreLocation. This enables it to display a GPS status bar in real time.

At this time, EOS Arrow GPS receivers and Geneq iSXBlue II + GNSS can work in the “Enable the External GPS” mode. To use the EOS Arrow 200 and iCMTGIS PRO for RTK work, you must use the free EOS Tools Pro app to connect to the RTK network.

How to advance to the next point to stake using iCMTGIS Pro?

“I remember in CMT Field Survey on the PC-5 I could select Next and it would take me to the next point to stake. It doesn’t seem to function
this way in iCMTGIS Pro. In iCMTGIS Pro, there’s a Node field with an arrow, but it doesn’t advance the user to the next point to stake.”

In iCMTGIS PRO and some of our other apps, the Point Stakeout function will let you stake any Point Feature or any node on a Line or Area Feature. For a Line Feature you can enter the Node number in the Node field, or tap the arrow to advance to the next node on the Line or Area Feature.

Therefore, to stake one Point Feature after another, you could first join the Point Features into a Line Feature in the order that you wish to stake them, and then select the Line Feature as the target for the Point Stakeout function. For example, to visit the plots sequentially while cruising a stand of timber, you could join the plot centers into a Line Feature then make use of the Point Stakeout function.

Wetland & Stakeout provides customizable data input form on the iPad

“Is the mobile app (to be run on an iPad) standalone??? Or, does it require a desktop version or license to set up the job and input forms? . . . Is the mobile app really customizable within itself, or is the setup done on the desktop?”

Yes, the Wetland & Stakeout mobile app is standalone and you can set up the Jobs within the app.

The app is a data input form design app incorporating the wetland delineation data entry forms as an application. The wetland delineation input forms are built-in templates that you can call up and save under the names that you specify. You can modify the form within the app, and you can also design your own data entry form within the app.

Each “Job” in the app is focused on collecting data at one sample point although your site layout can include other map shapes.

Which app to use for dividing up a piece of land to make paddocks

The Farming GPS GIS II and Farming GPS GIS III apps for iPad provide the functionality to digitize the property boundary and divide up the area by using the Hinge-Cut, Direction-Cut or Split method. In addition, Farming GPS GIS III provides the GPS data collection function that you could use to map out the outline of the property by walking/driving around it.

After creating the paddocks, you could use the Stakeout functions in Farming GPS GIS II or Farming GPS GIS III to help you put in the stakes along the property boundary.

For iPhone users, the iGPSGIS II will let you use GPS to map out the property boundary. You can then digitize the paddocks and use the Move Node function to adjust the paddocks to the desired shapes and sizes The separate Stakeout iCMT app can help you move along the boundary and drive in the stakes.

The GPS on the Apple iOS devices is not that accurate. You will need to get a compatible external Bluetooth GPS receiver. Those providing 1 – 3 m accuracy cost around $100 – $150. Sub-meter GPS receivers are quite expensive.

Marking Property Lines

“I have 25 acres of land and have found all the surveying stakes identifying my property. A number of the stakes are in the bush or a huge ravine so I can’t tell where the property lines are between the stakes. I would like to use the iGPSGIS ll to first record where the stakes are positioned, and then using GPS while walking in the bush / ravine to identify exactly where the property lines are and install fence posts.”

Yes, you can use iGPSGIS II (or iCMTGIS II for iPad) to record the positions of the stakes then create an Area Feature by joining the stake points. Yes, you can use iGPSGIS II (or iCMTGIS II for iPad) to record the positions of the stakes then create an Area Feature by joining the stake points. Or, if you are able to walk to each stake sequentially along the boundary, then you could log an Area Feature in the “Static” mode.

You can improve the accuracy of the recorded position by occupying the location at each stake for maybe 10-15 minutes to obtain an average position. Beware that inherently the GPS in the iPhone is not that accurate. Some users get a mapping-grade Dual XGPS-150, a Bad Elf GPS or Garmin GLO to get 1m – 3m accuracy. For sub-meter accuracy, you could check out the more expensive iSXBlue and EOS Arrow GPS receivers. The iGPSGIS II app can get the positions that these external Bluetooth GPS receivers send to the iOS device.

After you have the area boundary displayed in the app, you can eyeball your position on the map and try to stay on the boundary. Again, the GPS accuracy plays a role here.

Some users use our Stakeout iCMT app to help them get to a point or stay on a boundary line. Stakeout iCMT will report your position (distance, direction) with respect to a target point. It can also be set up to keep beeping as long as you stay on a boundary line.
