How to change the shape of a Line or Area Feature

A number of our iOS apps provide the Move Node function. A couple apps also provide the Insert Node function.

When you use Move Node to move a node of a Line or Area Feature, the shape will be changed. Beware, though, that there is not an undo function for Move Node. If you change your mind, you will need to manually move the node back to its original position or as close to it as possible.

The Insert Node function provides additional flexibility to change the shape of the Line or Area Feature. You can add additional nodes between two existing nodes and move the nodes to approximate the desired shape.

Map only shows grids in Partition & Stakeout app loaded on iPhone 7

“Downloaded app from Apple Store on July 13th 2017. Still reading and learning usage of software. Although, in attempting to use the Maps portion with GPS, no maps appear, strictly grids. App loaded on an iPhone 7; version 10.3.2. Can you assist with possible issues for correction? This is for personal usage, not commercial. Would like to stakeout and layout lot for new home.”

The Map function gets the map from Apple via wi-fi. Sometimes it helps to turn off wi-fi on your iOS device then turn it on again. Resetting the iOS device usually corrects the problem.

Please run the Apple Maps app on your iOS device. If you see the same screen of grids, then the issue should be due to the Apple Map server or a network problem.

How to create a data dictionary using iCMTGIS PRO

“I would like to ask about the ability for our software to provide the data dictionary? If yes, what is the process please? One of the engineers send me a sample shape file from the distribution assets at xxx, he asked if we can do data dictionary for him. Another question please, is it required to have the desktop version for icmt to develop the data dictionary or it is enough to have the iPad software?”

The Feature List functionality under the GPS tab of iCMTGIS PRO is for setting up one or more data dictionaries. The section on Feature List in the iCMTGIS PRO Help document describes this function and provides an example for creating a Feature List.

You can use iCMTGIS PRO or the desktop PC-GIS X to set up a Feature List. The Feature List file has the file name extension “.fbr“.

After a Feature List has been saved in iCMTGIS PRO, you can select it for any Job you do on iCMTGIS PRO.

You can open the engineer’s sample shape file in iCMTGIS PRO and look at the data records in Sheet View to find out what Values they have assigned to each Attribute. However, these are just the Values used during one data collection session and may not cover all the Values they have defined for the Attribute. The engineer should provide you with the full structure of the data dictionary.

Feature Topic1

Value2
etc.

Importing a DXF file into iCMTGIS PRO

“Hi I am having trouble loading a file into the unit. . . . My error says that it is required to be in LLA, but I would rather use New York East State Plane. Do I have to convert? If so, how?”

This problem is most likely due to the datum and coordinate system used. Please set up the datum, coordinate system, and distance unit in iCMTGIS PRO to match those used for creating the DXF file then load the DXF file.

If your DXF file was created in LLA, then please set iCMTGIS PRO to WGS84 and LLA. If your DXF refers to a newer WGS84 realization, then select that one.

Load the DXF in iCMTGIS PRO then change the coordinate system to NAD83_CORS96/CSRS98 and State Plane and select New York East State Plane.

The above instruction also applies to other CMTINC apps that provide the DXF import functionality.

GPS Position Averaging

“I use your Wetland Stakeout app with an Arrow GNSS receiver connected to an IPAD. Is there a way to collect features using position averaging with that app? If no, what APPS do you have that allow for position averaging?”

We have a few apps that provide GPS/GIS data collection functionality with position averaging:

For iPhone only: iGPSGIS II

For iPad only: iCMTGIS II, Utility Data Collection, Farming GPS GIS II/III, Forester GPS GIS II/III

For iPad and iPhone: iCMTGIS III, iCMTGIS PRO

Please let us know what other functionality you are looking for besides point averaging so we might help you identify the app to use. For example, will you want to be able to load a GeoTiff background map in the app? Will you need to export the data as a text file, or just in Shapefiles format? Will you be using a high-precision GPS receiver, such as an EOS Arrow or an iSXBlue II? Or, is a 2 – 5 m position accuracy good enough?

How to turn on Location Service

“I am experiencing some problems with my iCMTGIS PRO app. In order to successfully use the app it needs to have location services allowed while using the app. However when I open the app it doesn’t give the option to allow location services to have the location while I’m using the app. Could you help me out with this problem please.”

Location Service is provided by Apple. You can enable it under Settings on your device.

How to designate a different location as the starting point of a deed plot?

“I have a plot in Deed calls and stakeout and need to identify a particular pin as first node (since I have a lat/long ref for this pin). When attempting to use ‘Pick’ from the First Node tab I can select the desired pin and it is identified as ‘starting point’ but when clicking ‘back’ button this designation is lost and the plot continues to be located as if the actual first node I started drawing with is the reference node.”

Picking the first node means to relocate (translate) the entire deed plot to a new location by moving the first node to the location of the node you picked.

If you use the Pick function, you can select the node location to which the first node should be moved to translate the deed plot.

If you use the Pick GPS function and have GPS turned on, then the deed plot will be translated such that the first node is at the GPS position.

Your first node is where the deed calls originate from. If you want to start from a different location, then your deed calls must be rearranged to start from the call issued from that location.

You mention that you have the lat/long reference for one of the pins.
You could re-enter all the calls in the app using this as the first node. Alternatively, you could do the following to designate this as the first node and rearrange the calls:

1. Go to the Calls page and use Save As to save the calls to a text file (*.dcf).

2. Copy this .dcf file to your PC via iTunes.

3. Use a text editor such as Wordpad to view and change the .dcf file. You would change the latitude and longitude values for the First Node. In addition, in the Records section, you would cut the lines of text, starting with the call that corresponds to the new first node and ending at the last call, then paste these lines before the existing first call record.

4. Save the modified .dcf file under a new name.

5. Copy the modified .dcf file back to the documents folder of the Deed Calls & Stakeout app.

6. Open the modified .dcf file in Deed Calls & Stakeout. You should now have a deed plot that starts at the known location.

This same method can be applied to a deed plot created using Deed Calls & Stakeout as well as our other apps that provide the Deed Calls functionality, such as Deed Calls – Area – Perimeter, Deed Calls Pro, Forester GPS GIS II/III, Farming GPS GIS II/III, iCMTGIS III and iCMTGIS PRO.

By the way, if you find our apps useful, we would appreciate your posting a favorable review at the App Store. Thanks!
