Here's a fun little challenge. I have point locations of snakes, and I need to extract the habitats associated with each point from a land cover raster. Problematically, the points were taken along roads, not within the actual habitats in which the snakes were spotted. I would like to extract the values of the raster cells nearest the "Road" cells without modifying the land cover raster (it's 20GB). Currently I am just zooming in to each point and doing this manually, but thought there might be a way to do it more quickly. Thanks for the help!
Shift raster shift the points, then extract values to points. With any luck you will nail all non-roads in one go.. If not, get shifty in another direction and try again, and combine results... simply dump your observations that fall on road. You might even pick up habitat on the otherside of the road, perhaps where the snake was trying to get to
