Hello! I am putting together a benchmark dataset for tree crown segmentation - do you have data and would you like to join our effort?
Call for data: we're looking for exact tree crown segmentations (rather than bounding boxes) collocated with some form of (very) high resolution aerial imagery - drone or satellite. Segmentation derived from TLS or ALS data is absolutely ideal, but high quality manual labels are also ok.
In return, we can offer:
- Co-authorship on a publication (likely at some point in 2023)
- Access to the dataset for analysis prior to the full release
If there's anything else you think that I/we might be able to offer in return, feel free to ask!

You should definitely talk with Ben Weinstein and co (the folks behind DeepForest), if you haven't already!

Bluesky have a commercial tree crown dataset available covering most of Great Britain (England, Wales and parts of Scotland). There is a canopy layer with approximate outlines of each canopy (the image on this page shows just circular crowns). It's created using aerial imagery.
