z-axis coordinates of vector data, specified as a 3-D array that can be combined with X and Y to form a grid of coordinates. You can use the meshgrid function to create the arrays. Z must be the same size as X, Y, U, V, and W. U— x-components 2-D array | 3-D array x...
Hi, I was working with some files today, and I got something really weird, the vector file can be in gpkg or shp and we can get the same result, in particular I was getting errors from R/sf with ParseException: Unexpected EOF parsing WKB...
