Coordinates tracing 2D outlines of beaks (birds and squid)
Description
Two-dimensional coordinates for lines traced onto images of beaks.
- This is a .zip archive xy coordinates (250 files, .txt); and a list of specimen names (1 file, .csv).
- All images traced in FIJI.
- For each specimen, there is a trace of the beak rostrum and a separate trace of the beak bite surface.
- Each trace file should be a list of xy coordinates that ends at the beak tip. This must be checked/verified/corrected for all files before running any analyses! I recommend visual inspection by plotting each beak dataset as a scatterplot in a color spectrum (rainbow, etc.).
- These were traced over pixel images, so each file has a different number of xy coordinates (depending on the pixel resolution/image size that was traced).
- All bird specimen images were downloaded from Phenome10k.org
- All cephalopod specimens were traced from images published in:
- Xavier, J. C. & Cherel, Y. 2009 Cephalopod beak guide for the Southern Ocean. British Antarctic Survey.
