Step 3: Explore Sample Frames

Time: ~2 minutes

You have observations through time as data capture events. Now QRiS needs to know where to summarize them.

Add the sample frames

In the QRiS Project Explorer:

  1. Expand the project Inputs.
  2. Find the sample frame named SF.
  3. Right-click SF → Add to Map.

You should see three sample-frame polygons dividing the Bailey Flat riverscape.

What to know

A sample frame is the area within which QRiS calculates metrics. Sample frames let you compare one part of a riverscape with another, or compare the same area through time.

For this quickstart, the three sample frames are already built. You will use them as-is.

You have:

  • DCEs = observations through time
  • Sample frames = where QRiS will measure them

Next, you'll tell QRiS what to calculate.
