Through the process of creating an orthomosaic, DSM, and DTM, sometimes the edges can look a little... well, edgy! The edges always have the most distortion as they are comprised of fewer photos than internal areas.

So if you'd like to trim down and tidy your datasets, follow these three simple steps:

  1. Select the dataset

  2. Hold the control key (cmd on mac) and select a polygon feature that you've already drawn or imported

  3. Click the 'crop to polygon' button on the top menu bar. You can also use the keyboard shortcut - 'K' to perform this operation

Top tips

  • This will only work when a single polygon is selected

  • You can also select a polygon layer (not just the feature) as long as that layer only has one feature in it

  • If you do want to crop to more than one area in a single operation, create separate polygons first, and then use the 'union' tool to merge them. They will then appear as a multi-part polygon, but still a single feature. Proceed to crop to polygon as usual

  • Use ctrl + z to undo your crop; ctrl + shift + z to redo it after an undo

  • If you realise at a later time that you don't want that crop, simply remove the dataset from your project and add it back in

  • The crop that you apply will only persist in the project, and any project duplicated from the same. It will not affect the dataset that you can see in your dataset repository or on FAIR Geo

Other software packages use a variety of names for this same operation - you might see

  • Clip

  • Intersect

  • Frame

  • Mask

  • Crop

  • Crop to shape
