How to record the RMS value displayed in iCMTGIS PRO?

In the “Enable the External GPS” mode, iCMTGIS PRO can display on the GPS Status line the RMS value sent over by such GPS receivers as the iSXBlue II GNSS, SXBlue Platinum and the EOS Arrow series GNSS receivers.

Some iCMTGIS PRO users have requested the ability to save the GPS RMS information along with the recorded Features. We are working on adding the RMS value and some other GPS status information to the built-in Attributes List. When the new built-in Attributes List is available, you will be able to select the RMS from the list and add it to the Feature Topic as an Attribute. Then the RMS values for the Features recorded via the GPS Data Collection function will show up in Sheet View, and you will be able to export them along with the other Feature information.

Feature Attribution in iCMTGIS III

“When we start collecting data by Collect button a separate window is displayed to the bottom of the screen, showing our added field names, but when we store a point, there is no data seen in that table, however if we use the table icon at the left top of the iCMT, the data is present there, this may give a bad impact if this is without reason.”

The Attribute fields you’ve added to a Topic are for tagging any Features in the Job file.

The Attribute fields for GPS Data Collection need to be defined in a Feature List, which you can associate with any Job file.

When you do Job – Open Job, you will see the Feature List field. Right now it’s probably showing “NONE”. You could select the built-in Feature List “utilities” (in iCMTGIS III) to work with and collect data for the Features defined in that Feature List.

To make your own Feature List with your own Features and Attributes/Values, please select GPS then select Feature List. Here After you select “New”, you can define the type of Features (Point, Line or Area), the data collection parameters and the Attributes and predefined Values for those Features.

While you collect data using the Feature List, you can select or enter the Attributes for the Feature being recorded. These Attribute/Values will display in Sheet View at the bottom of the screen (if you have activated Sheet View display by tapping the Sheet View icon on the right side at the top.)

Which of your apps will let me select from a drop-down list in a table?

The Feature List facility in iCMTGIS II and iGPSGIS II will let you select an Attribute Value from a drop-down list while doing GPS mapping and data collection.

The Utility Data Collection, Farming GPS GIS II and Forester GPS GIS II apps provide a newer Feature List structure that can be used for GPS mapping/data collection as well as data attribution in the Sheet View table.

Farming GPS GIS and Forester GPS GIS do not provide the GPS Data Collection function but provide the new Feature List capability. This means that you can set up the Feature List with the frequently used descriptions and/or values for each Feature Topic. After you have added the Feature Topic from the Feature List to your job map and digitized some Features, you will be able to easily add a description to a Feature by selecting it from a drop-down list in the Sheet View table.

Coming soon is a form design app named Wetland – Stakeout. With this app, you will be able to design your own data collection sheet to record such things as the species, DBH and the number of log segments for each tree at a point. For each variable in the sheet, such as  the species, you can define a drop-down list.

How to create new point, line and polygon features with associated attribute fields and values?

There are a few ways of adding Points, Lines and Polygon Features to a map job.

1) Digitization

You will first need to create a new Topic layer on which to store the Features. Specify the correct topic type (Point, Line or Area) for the New Topic. Also, Farming GPS GIS, Forester GPS GIS and Utility Data Collection will let you add a Topic from the Feature List associated with the map job.

The Tools menu provides the Add Point manually, Add Line manually and Add Area manually functions. When a Point Topic is active, you can digitize Point Features. When a Line Topic is active, you can digitize Line Features. When an Area Topic is active, you can digitize Area Features.

Use the Edit Topic function to add Attribute fields to the Topic.

After digitizing the Features, you can turn on Sheet View (the right-most icon at the top) and enter the values. Farming GPS GIS, Forester GPS GIS and Utility Data Collection provide the ability to select pre-defined attribute values from within the Sheet View.

2) GPS Data Collection

The iCMTGIS II, iGPSGIS II and Utility Data Collection software apps will let you map points, lines and areas using GPS. When you collect GPS data, you can record the attribute values at the same time.

If you have a Feature List defined and associated with a job, during GPS data collection you can simply select one of the Values instead of having to enter the data by hand. The Feature List function is listed under GPS. It lets you define the Feature Topic Layers, the Attributes and the Values for the Attributes as well as the GPS data collection parameters.

Select Main Menu\Job\Current Job to get to the Job Setup screen. Here is where you can select the Feature List to be associated with the active Job. The iCMTGIS II, iGPSGIS II and Utility Data Collection software provide a Feature List file named “park.fbr” as an example.

The GPS data collection function is provided under GPS. Please see the built-in Help document for the procedure for recording various types of points, lines and areas. This document is available in PDF format upon request.

3) For Point Features, there are also the Traverse method under data collection and the Add Point by Coordinates function that you can use to create new points.

How to tag a digitized point with attributes?

The digitizing functions in iCMTGIS and iGPSGIS permit you to quickly add Points, Lines or Areas onto Map View.

To be able to assign descriptions to the points that you have digitized manually, you must first add the Attribute Names for the Point Feature Topic, if you have not already done so when creating the Topic.

To set up Attribute Names for a Feature Topic, tap the Main Menu, select Topic then select Edit Topic. Select an existing Topic  Name, such as “Corners”.

Tap the Add button to add a new Attribute, such as “ID”.  Tap the green checkmark to return to Map View.

Now tap the Feature Properties icon (showing a pair of spectacles) then tap the Attribute button. For each listed Attribute you may double-tap the corresponding Value field and add or change the displayed value. If you wish to stay in the editing mode then tap the eyeball icon (View mode ) to switch to a pencil icon (Edit mode).

If you manually digitized a Feature into a Topic that was set up in a Feature List, then the Attribute fields assigned to the Feature Topic will be displayed.
