Sometimes you collect a little extra data or have some edges which aren't smooth. Here, we will explain how to crop your data.
Please note that Cropping works best on Google Chrome or Mozilla Firefox browser​.
In this tutorial, we'll be looking at the Example Data from the How to Process Datasets documentation.
To start cropping, click on the Data Panel pull-down button in the side panel.
Then click on the crop button in the Data Panel.

Button to start cropping a plan highlighted in red. Blue line showing the current boundary around a plan, with the anchors as white dots, and new anchors as grey dots.
This will show you the current border around a plan.
You now have several options.
To move an anchor (and hence change the edge), click and drag one of the white dots to an appropriate location. We've selected the top right in this example.
You'll notice the data layer is automatically cropped to where this new anchor location.
We have automatically created a few too many anchors for this map. To remove an anchor, just single click on the anchor you would like to remove (white dot). I've now thinned out and moved a few of the anchors.
If we've stripped a few too many, you can add additional anchors by clicking on the semi-opaque anchors, and dragging it.
This will add an additional point.
The crop will be saved after each edit. Once you're happy with your crop, you can unclick the blue crop button again to hide the markers and boundary.
