Raster termplate for estimation

Given a set of observations, define a estimation template.

estimation_mask(x, buffer_size, res = buffer_size/8)

Arguments

x	An object of class sfg, sfc or sf, including particularly objects of class sr_obs. Geographical objects that determine the estimation region.
buffer_size	Numeric. Expansion of the extent around the convex-hull of x. In the units of the data (e.g. m, or arc-degrees).
res	Numeric vector of length 1 or 2. Resolution of the raster template. Size(s) of the pixel, in metres.

Examples

## Some random points in the unit square
pp <- st_multipoint(matrix(runif(30), ncol = 2))
(em <- estimation_mask(pp, buffer_size = .3, res = .1))
#> class      : RasterLayer 
#> dimensions : 15, 15, 225  (nrow, ncol, ncell)
#> resolution : 0.1, 0.1  (x, y)
#> extent     : -0.2925914, 1.207409, -0.2194667, 1.280533  (xmin, xmax, ymin, ymax)
