Is there a video tutorial to show me how to set up a Feature List?

We’ve just uploaded a new video tutorial. Here you go:



“I’m hesitant to spend $300 for the pro app if the $95 or $200 apps will suffice but I’m having a difficult time finding a comparison of features among the apps.”

Built-in Attributes 512x384

The three apps in the iCMTGIS-series all provide real-time GPS/GIS data collection and mapping functions. They will let you add user-defined Attributes for the recorded Features either manually or via a Feature List (attribute table). They will let you import and export Shapefiles. The differences are in the additional functionality provided by the more expensive apps.

If you just need to use GPS to map Points, Lines and Areas and record their associated descriptions, iCMTGIS II will do. iCMTGIS II can display the built-in Apple Map as background. If you would like to use an off-line geo-referenced background image, you will need to first use the optional PC-GIS software to convert the GeoTiff, GeoJpeg, ECW or MRSID files to the .pim file format. The .pim map can work in the “moving map” navigation mode. (Many of our existing customers already have the PC mapping software.) iCMTGIS II only works on an iPad device. Its iPhone equivalent is the iGPSGIS II app.

iCMTGIS III and iCMTGIS PRO can run on iPad and iPhone devices. These two apps will let you load a GeoTiff image or a .pim image as background map. They also provide a built-in Attribute List from which you can choose as additional Attributes for the Features. One of the screen shots displayed here shows the current list of built-in Attributes that you may elect to include in the data records for the Features recorded using GPS. Other additional functions are also provided in these apps, which help you stake points/lines/areas, create Features by entering distances and bearings, as well as classify, sort or perform a search on the Features in a Topic layer, import and export Point Features via a text file, etc.

iCMTGIS PRO has all the functionality of iCMTGIS III plus the Contour/Volume and Create Buffer functions. What sets it apart from the other two apps is that it provides the ability to receive the NMEA message stream directly from a few specific external GPS receivers. When the “Enable the External GPS” option is selected, iCMTGIS PRO will get the GPS information directly from the external GPS receiver rather than the iOS CoreLocation. This enables it to display a GPS status bar in real time.

At this time, EOS Arrow GPS receivers and Geneq iSXBlue II + GNSS can work in the “Enable the External GPS” mode. To use the EOS Arrow 200 and iCMTGIS PRO for RTK work, you must use the free EOS Tools Pro app to connect to the RTK network.

Do the default descriptions work for digitized Features?

A user wrote: “We have been looking at the use of iCMTGIS for field data collection and like the ability of the program to quickly and easily collect data with custom built feature lists with preset attributes and values. I have noticed one downside with the feature lists that, if corrected, could save much valuable time. I share my experience in case you should wish to make a good program even better. Having the ability to use the default value checkbox saves quite a bit of time when collecting points by GPS. It allows the user to avoid clicking the drop down for each individual attribute, or worse, manually typing in the value for each attribute. However, if I place a point manually, even if I have set default values in the feature list dialog box, each attribute starts out blank and I must use the drop downs to select the value I desire. Admittedly, this does not take much time for a single point, however if I should wish to collect many data points, the time really adds up. What are the chances this could be fixed in an update?”

Although you can assign predefined attribute/values to a digitized point, the Feature List is mainly defined for and tied to the function for storing GPS data.

2/16/15 Update: A number of our newer GPS/GIS apps employ an enhanced Feature List that can also be used for adding descriptions to manually added (digitized) Features. If you have specified a default Value and its associated symbol in the Feature List, then that will be given to the digitized Features. Currently, this enhanced Feature List is implemented in Utilities Data Collection, Farming GPS GIS, Forester GPS GIS, Farming GPS GIS II and Forester GPS GIS II. It will also be implemented in iCMTGIS III to be released in the near future

Expediting data collection

Using a Feature List for data collection speeds up the data input tremendously. You can take this one step further by specifying a default description for each Feature Attribute of interest.

For example, you’d probably expect most of the fire hydrants to pass your inspection. Therefore,  in the ht.fbr Feature List,  you would want to specify “Pass” as the default value for the “Condition” Attribute of the Hydrants Feature Topic. 

To do so, first open the ht.fbr Feature List . Highlight the “Hydrants” Feature Topic then tap the Attribute tab at the bottom. Select the “Condition” Attribute then tap the Value tab at the bottom. Tap the Default box for the Value “Pass”. Tap the Save button to save your selection.

If you wish to also set a default value for the “Type” field, tap the Attribute tab then select “Type”. Then tap the Value tab and mark the Default box for the desired Value.

The screen to the right shows the selection of “Medium” as the default Value for the “Size” Attribute of the “Trees” Feature Topic.

The default Values that you specify will automatically fill the data input field for data collection. While enjoying this convenience, please remember to select the appropriate description from the predefined List of Values when you encounter a Feature that does not conform to the norm.

Furthermore, if for instance you come to a street tree that’s not any of the predefined species, you could manually enter its species name into the Value data input field. However, if your GIS system cannot accept any species data outside of the predefined list, then you could lock the “Species” Attribute. The Attribute Lock box is located to the right of each Attribute. Activating the Attribute check forces the user to enter only those Values listed in the Feature List for that Attribute. This option prevents the user from entering unwanted or misspelled values.

Similarly, activating the Lock box for a Feature Topic will force the user to enter only Feature Topic names contained in the Feature List. This option prevents the user from entering unwanted or misspelled Feature Topics. If this box is not checked, the user is allowed to enter any Feature Topic name through the keyboard of the data collector.

Once you have completed the setup for the ht.fbr Feature List, you may associate this Feature List with any data collection job that calls for the same Features, Attributes and Values setup.
