Why does spatial data manipulation have to take so long...reprojecting a 5m raster of the whole of Great Britain surely can't cause too much trouble 🙈

Been struggling with an #RSpatial problem today, wondering if anyone here has any insights:

I want to find the nearest polygon to a point excluding the polygon that contains the point.

Been working with st_nearest_feature and excluding the containing poly from the dataset but wondering if there is a better way as I have a lot of points... Also struggling to work with sf and purrr together but that's another question!

Massive credit to the people in Switzerland who made this aerial imagery open access and freely available to all for research, innovation + more 🚀 See it on Google Earth Engine at https://developers.google.com/earth-engine/datasets/catalog/ORTHO_Switzerland_SWISSIMAGE_10cm #gis #geocomputation #map

Aerial/satellite imagery from Google and other providers is now good enough to allow estimation of road widths. Anyone with Google Earth Engine experience up for helping to figure our how? Existing codebase for rivers: https://github.com/seanyx/RivWidthCloudPaper #geo #geocomputation #geocompx
