Collecting GPS/GIS data for a Point Feature Topic

To record data for a street tree, hold or place the data collector by the tree. Make sure the “ht” job that we created before is the currently active job. Tap the tool icon that shows a GPS satellite then select Collect.

Tap the New button to set up a new Feature Topic for collecting data.

Because we have set up the “ht” job with an associated Feature List (ht.fbr), when you tap the data entry field for Name, you will see the list of Feature Topics that you have set up before.

Select the “Trees” Feature Topic.

The first Feature is assigned the Feature ID Trees001.

You will see that the data collection parameters displayed are exactly what you want for collecting the street tree data because you have previously defined them for the Trees Feature Topic in the ht.fbr Feature List.

Tap the green check mark at the top to confirm the setting and advance to the “Collect” screen.

Now, specify the descriptions to be stored along with the position data. For example, if the feature is a pine tree, then select “Pine” from the list of predefined species. You will notice that “Medium” is displayed in the Size field. That’s because we have defined it to be the default Value for the “Size” Attribute.

If you do not wish to use the default symbol for the Point Feature, you could tap the symbol button on the lower-left corner and select the tree symbol from the bottom row of the displayed symbol patterns. You could also assign a green color to the tree symbol.

Tap the Store button to begin logging GPS data. Hold the recording device still for the session time specified for the Feature Topic, which is 30 seconds in our example.

When the time is up, the Tree Point Feature is recorded and the Feature ID advances to Trees002.

Go to the next street tree. Select the appropriate descriptions and tap the “Store” button to record the data for Trees002.

Suppose a fire hydrant comes up next. Tap the New button to tell the application that you will be recording data for a different Feature Topic. Select the Hydrants Feature Topic Name then tap the green checkmark to confirm. Select the appropriate hydrant type and accept the “Pass” condition if it applies. Tap the symbol button on the lower-left corner and select the hydrant symbol from the top row of the displayed symbol patterns. Tap the Store button to log the GPS data for Hydrants001.

Next up will most likely be another street tree. Tap the New button and select the Trees Feature Topic Name then tap the green checkmark to confirm. Switch back to the tree symbol before logging the GPS data.

Continue this process until you have collected all the data that you need.

To get out of the GPS data collection mode, tap the Exit button.

Tap the Zoom-fit icon at the top if you wish to see all the Features displayed on the same screen.

The Point Features you have logged will be represented by their respective point symbols on the map.
