Continued thread

we ran a multi-decade extraction of points-in-time for 46000 points 1993-2024 (at bottom level, it's variable so we indexed the level upfront for each point) ran this the "traditional way" using #terra #GDAL to extract points from relevant layers (point-sets grouped by date,level) for salt,temp,u,v,w,mld - ran on 28cpus with #furrr/#future took ~80min

will get a public dataset to repeat the example for illustration (elephant seals I hope)

IGNORE! This was my error!

potentially stupid #terra #rstats question:

I have a raster, r, say where some cells have values and others don't and a circular buffer, buff.

I do:

terra::extract(r, buff, xy=TRUE)

some of the returned x,y coordinates are (0,0) which are not in the range of the projected coordinates of r or buff.

Why is that?
