Apps for recording GPS points

“I have downloaded your Deed Calls application and it works great. However, I am looking for an additional feature and I’m unsure which product will get me what I would like. I need to enter deed calls AND use the GPS to set points all in the same area. With deed calls, it seems to allow me to set the starting point with GPS, but after that, seems that I have to have the deed calls.”

The PickGPS function just grabs one GPS fix. This, in combination with the GPS that comes with the iPhone and iPad devices, which lacks accuracy, will not give you an accurate starting point for your deed plot. You will want to check the deed plot against the satellite map to see it is located approximately correctly.

The Deed Calls Pro app provides both the ability to create a deed plot and the ability to digitize points using PickGPS.

Our Forester GPS GIS III and Farming GPS GIS III for use with iPad devices and the iCMTGIS III and iCMTGIS PRO apps for use with either iPhone or iPad devices, provide the Deed Calls function plus a GPS Point data collection function that will let you record multiple GPS fixes at one location and compute the average position.

The accuracy of your work will still depend on the precision of the GPS receiver you use. Some of our customers use the Dual XGPS-150 or the Bad Elf GPS 2200 to get 2-5 meter horizontal accuracy. Other customers use high-precision GPS receivers (iSXBlue II+ GNSS and EOS Arrow GNSS) to obtain better position accuracy.

How can I make sure I’m capturing points meeting a PDOP threshold?

If you are using iCMTGIS PRO and an iSXBlue II or EOS Arrow GPS receiver, you can set the PDOP limit for GPS data collection as follows:

1. Turn off GPS from all apps on your iOS device.

2. Select Main Menu – Setup and mark the check box for “Enable the external GPS“.

3. Select the appropriate device protocol for the GPS receiver.

4. Tap on the pull-down arrow for PDOP Mask and select the desired PDOP Mask level. If you only want to record position data for which the elevation can be computed, then also mark the “3D Only” check box. Tap on OK to save the setting and close the screen.

5. Tap on the GPS icon then select “Turn external GPS on”.

If I purchase iCMTGIS PRO for my iPhone, can I also install it on my iPad?

Some of our apps were designed specifically for the iPhone or specifically for the iPad, but iCMTGIS III and iCMTGIS PRO were designed for use on both the iPhone and the iPad devices.

You can install your purchase of this app on your iPhone and iPad devices as long as your devices use the same Apple ID.

A related question:

“If I get a new iPhone in the future, will I be able to re-download and install iCMTGIS Pro on my new device without having to purchase it again?”

Once you have purchased the iCMTGIS PRO app, you can install it in any new iPad or iPhone device that you purchase as long as the devices use the same Apple ID.

Please note that our iOS apps are sold via the Apple App Store, and all purchases and installations are governed by Apple.

 

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.

iPhone app to map property for forestry work

“I am looking for a gps system that is sub meter that I can Bluetooth to my phone and run an app that helps me plot property for forestry work. I also need to be able to import and export shape files.”

As you need sub-meter accuracy, you should get a high-end GPS receiver like the iSXBlue II or the EOS Arrow receiver to connect to your iPhone via Bluetooth.

iGPSGIS II is a professional GPS/GIS mapping and data collection app for use on the iPhone. You can use it to map points, lines and property boundaries (Area) and import and export data in Shapefiles format.

How to recover custom configuration after updating iCMTGIS III

“I’ve been puzzled by question that whereas iCMTGIS iii keeps its settings every time we updated it, a few settings have gone to the default (for us: Elevation and Angle, and Data Collection). Can we have:
1) The configuration not touched during update (unless configuration parameters changed);
2) Float number for the Local Time Offset in Data Collection?
Otherwise, the iCMTGIS-iii has been working fine.”

The settings for Elevation and Angle and Data Collection are saved in the file named “cmtgis3.cfg“.

After setting up the desired parameters, you can copy cmtgis.cfg to your PC for safekeeping.

After a software update, the app must go back to the default system configuration, but you can restore your custom configuration.

To do so, please first run the app and open a Job so you will be able to access the app’s Documents folder.

Then close the app by double-clicking the Home button and then flicking the app screen upward and out of sight.

Now copy your custom cmtgis3.cfg back to the app’s Documents folder to overwrite the default configuration file. You should see your custom settings for Elevation and Angle and Data Collection.

iCMTGIS III updated to version 1.1.5

The changes in this update are:
1. Allow GPS data collection to continue in the background when user presses the Home button or when screen is locked.
2. Display same elevation data in Feature Properties screen and the pop-up in Map View.
