geo_trianglegrid: Trianglegrid

In geoops: 'GeoJSON' Topology Calculations and Operations

Description

Takes a bounding box and a cell depth and returns a set of Polygon's in a grid.

Usage

geo_trianglegrid(bbox, cell_size, units = "kilometers")

Arguments

bbox	extent in [minX, minY, maxX, maxY] order
cell_size	(numeric) the distance across each cell
units	(character) used in calculating cellSize, can be degrees, radians, miles, or kilometers (default)

Value

FeatureCollection<Polygon> grid of polygons

Examples

geo_trianglegrid(c(-77.3876, 38.7198, -76.9482, 39.0277), 3, "miles")
geo_trianglegrid(c(-77.3876, 38.7198, -76.9482, 39.0277), 10, "miles")
geo_trianglegrid(c(-77.3876, 38.7198, -76.9482, 39.0277), 30, "miles")
