Is CMT working towards including the OCRS within the ICMT GIS PRO software?

“I am using the EOS Arrow 200 with ICMT GIS PRO on an Ipad. I am wanting to transform my GPS points to the low distortion projections Oregon Coordinate Reference System. I haven’t been able to create a user defined projection to match the OCRS zones. My questions for CMT: Is CMT working towards including the OCRS within the ICMT GIS PRO software? If so would this be available as an update any time soon? If the OCRS zones are not going to be available for ICMT GIS PRO- would the PC GIS PRO software work to build the OCRS zones to download into ICMT GIS PRO?”

Thanks for using our iCMTGIS PRO. This app has the standard LLA, UTM and State Plane coordinate systems built in. Different states and countries (e.g. SWEREF99TM for Sweden, KTM-KUDAMS for Kuwait) might use different projections. You can use the optional PC-GIS X software to create user-defined datums and Transverse Mercator, Mercaator, Oblique Mercator, Lambert Conformal Conic, Albers Equal Area Conic and Double Stereographic projections. After you have copied the user_dat.sys and user_cor.sys files created by PC-GIS X to your iCMTGIS PRO documents folder, iCMTGIS PRO will let you select the user-defined coordinate system to use.

As the OCRS zones refer to the NAD83 datum, you don’t need to create a new datum.

How to determine the direction of a straight line in iCMTGIS PRO?

Line Segment Label

A number of our apps provide a function in the Feature Properties screen for labeling a line segment. In some apps, such as iCMTGIS III and iCMTGIS PRO, after selecting the line segment, you would tap on the “Show Label” tab then mark the check box for “Show Segment label“. In some other apps, such as Wetland – Stakeout and Deed Calls Pro, the “Show Segment label” check box is in the main Feature Properties screen.

With the Angle System set to “Bearing“, the line segment label will show something like SE. This indicates that the line is pointing to southeast.

iCMTGIS III and iCMTGIS PRO also provide the View Deed Calls function. In the Deed Calls screen, the starting node of the active line segment is indicated with a green node. In addition, the bearing of the straight line segment is displayed under Calls.

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.)

 

Use iCMTGIS PRO to export Feature data to Excel file

“I have a client that uses the Arrow 100 device connected to his Laptop computer. I was inquiring about capturing lat/long coordinates in Excel and they sent me to you and your software. My client records thousands of coordinates and loads them 1 by 1 into an Excel spreadsheet along with some other data. The ideal process we would like to set up is to have each measurement captured in real time by the device uploaded into Excel immediately. Is there a way to accomplish this with your software?”

iCMTGIS III and iCMTGIS PRO will let you record additional information with each GPS position in real time and save it to a Job file. When done collecting data for a bunch of points, you can export all the data to an Excel file. It does not save each record directly to Excel in real time. For Point Features, you can also export the data to a text file.

How to delete Jobs and Features in CMT GIS PRO?

“First—wondering how to delete jobs in cmtgis pro is I can start over fresh. Just go to iTunes and delete the files in the file sharing are??? Same with Features. Not sure how to edit or delete features in the feature list or edit attributes once the feature has been created.”

1. Yes, to delete an entire Job, please connect your iOS device with iTunes, select the Job files in the File Sharing area for the app, then click the Delete button on your PC keyboard.

2. The Feature List is made up of three main sections. To delete an entire Feature Topic, select that record under “Feature” then tap on the Delete button. To delete an Attribute for the selected Feature Topic, select that Attribute then tap the Delete button. To delete an assigned Value for the selected Attribute, select that Value record then tap the Delete button.

To edit an Attribute, first select it then choose the type. If it is of the “List” type, you can tap the Value section then tap the Add button to add one or more Values to assign to the Attribute. If you wish to assign specific symbols or patterns to the Values, then mark the “Activate Pattern” check box. Please see the built-in Help document for details.

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

Value1
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.
