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.

What to do when GPS is not available

The TRAVERSE function in iCMTGIS II and iGPSGIS II is a tool that lets you continue mapping multiple Point Features when a good GPS signal is not available.

To use the Traverse function you will first establish a reference point. This could be the last GPS point logged, or any Point Feature in the job. The new points will be created based on slope distance, slope and azimuth information for the imaginary straight line going from the reference point to the new location.

You could use the Side mode to do multiple “side shots” from the same reference point. For example, after logging a GPS point outside of a cave, you could use that as the reference point and take distance and angle measurements to the artifacts you’ve discovered inside the cave. Enter this information into the Travers Side data fields and the locations of the artifacts will be recorded in your job file.

Or, you could use the Traverse mode  to traverse to a new point that will then be used as the reference point for the next traverse point. This method can be used for storing vertices for lines or area boundaries.
