1. Overview: GPS metadata can drive survey logic 0:00
The video demonstrates how to pull GPS metadata into survey questions using conditional logic.
This works for:
Points
Lines
Polygons
The goal is to automatically populate survey fields with metadata like altitude, accuracy, timestamps, and more.
2. Add point geometry metadata to a survey question 0:14
Open a survey that includes a geometry question for points.
Add a decimal-type question that will store GPS metadata.
Go to the question’s Conditional Logic tab.
Add a conditional rule and choose:
Record Geometry → Geometry → Altitude
This makes the decimal field capture the point’s elevation when a point is recorded.
The same approach can be used for:
Accuracy
Timestamp
Bearing
Speed
3. Use line geometry metadata for tracking data 0:58
For a line geometry question, you can capture metadata from a tracked line.
In conditional logic, select line-related geometry metadata such as:
Start date
End date
This is useful when you press record to begin tracking and then stop/end the line later.
The survey can store when the line tracking started and ended automatically.
4. Use polygon geometry metadata 1:16
Polygon questions can also use conditional logic to capture metadata.
One example shown is adding the polygon start date.
This lets the survey record timing information associated with the polygon feature.
5. See the metadata populate when features are created 1:42
The demo shows the survey running on the website.
When a point is created, it grabs the current location and fills in metadata like:
Elevation
Accuracy
On the computer, elevation may not appear because the device does not provide it.
For a line, tracking and saving the feature would populate the start and end dates.
You can also copy metadata from an existing line feature saved in Features.
The same concept applies to polygons.
6. Key takeaway 2:21
Conditional logic can now be used to pull GPS metadata into survey fields.
This works across points, lines, and polygons.
It enables surveys to automatically capture useful feature metadata without manual entry.
