Create convex hulls of area covered by each fish #1

Used chull to create convex hulls. Not sure how to visualize them by fish.

Need to bring them into QGIS so I can zoom in and create shape files?

mstuart1 commented 4 years ago

Apparently I need a separate hull file for each fish. There are 65 fish. While visualizing these hulls would be nice, ultimately I need to know the area of each hull, which I don't need to visualize to calculate.

Was able to calculate area of the convex hulls. Created the hulls in the creating-convex-hulls.Rmd and am calculating area in the hull-area.Rmd.

Fish with areas over 500m^2 - making notes in the weird-clownfish slack to make these easily searchable.

137518.18	1664 - this fish was always captured at Wangag. Plotting the points shows something is wrong with the hull generator code. Go back and fix.
