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 FireFox browser.
In this tutorial, we'll be looking at the Example Data from the Map Engine tutorial.
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.
- Move an anchor
- Remove an anchor
- Add an anchor
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.
Moving an anchor changes the crop boundary for the data layer.
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.
Add an additional point by clicking and dragging one of the semi-opaque anchors.
This will add an additional point.
The larger area after dragging the anchor.
The crop will be saved after each edit. You can hide the markers and boundary by unclicking the Crop button again.
