Create fishnet of regular grids
Description
The fishnet function creates a regular grid of locations covering
the study area at various grain sizes.
Usage
fishnet(mask, res = 0.5)
Arguments
mask
a vector polygon covering the boundary of the survey region.
res
the grain size of the grid cells in decimal degrees (default).
Value
A spatial vector polygon object of equal area grid cells covering
the defined area.
