In sustainablefarms/sflddata: Data Extraction Methods for the Linking Data Project

Divide points into tiles

Description

Divide points into tiles

Usage

divide_into_tiles(points, cellsize = 1, buffer = 0.01)

make_grid_buffer(points, cellsize = 0.1, overlap = 0.01)

tilearoundobj(sfobj, buffer)

Arguments

points	An sf object to cover with a grid. Could also be a bbox object.
cellsize	is the size of a single cell
buffer	A numerical distance of a buffer to include around sfobj in the output tile
overlap	is the amount of overlap of each cell
sfobj	An sf object

Value

A list. Each element contains a slot 'tile' which is an sfc_POLYGON object, and a slot 'pts', which is a an sf object of points covered by the tile with sufficient buffer

An sf multipolygon object made of squares that overlap by buffer, and cover the region bbox expanded by buffer.

an sf polygon object that is rectangular

Functions

• make_grid_buffer: Creates a full grid of overlapping polygons that covers sfobj.

• tilearoundobj: Creates a single rectangle around an sf object
