Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
@turf/hex-grid
Advanced tools
@turf/hex-grid is a module from the Turf.js library that allows you to create a hexagonal grid within a bounding box. This can be useful for spatial analysis, data visualization, and geographic information system (GIS) applications.
Create a Hexagonal Grid
This feature allows you to create a hexagonal grid within a specified bounding box. The `bbox` parameter defines the bounding box, `cellSide` specifies the length of each hexagon's side, and `options` can include units of measurement.
const turf = require('@turf/turf');
const bbox = [-96, 31, -84, 40];
const cellSide = 50;
const options = { units: 'miles' };
const hexgrid = turf.hexGrid(bbox, cellSide, options);
console.log(JSON.stringify(hexgrid));
d3-hexbin is a module from the D3.js library that provides tools for creating hexagonal binning layouts. It is particularly useful for data visualization in web applications. Compared to @turf/hex-grid, d3-hexbin is more focused on visual representation and less on spatial analysis.
h3-js is a JavaScript library for working with Uber's H3 hexagonal hierarchical geospatial indexing system. It offers more advanced features for spatial indexing and analysis compared to @turf/hex-grid, which is more focused on simple hexagonal grid creation.
Takes a bounding box and the diameter of the cell and returns a FeatureCollection of flat-topped hexagons or triangles (Polygon features) aligned in an "odd-q" vertical grid as described in Hexagonal Grids.
Parameters
bbox
BBox extent in [minX, minY, maxX, maxY] ordercellSide
number length of the side of the the hexagons or triangles, in units. It will also coincide with the
radius of the circumcircle of the hexagons.options
Object Optional parameters (optional, default {}
)
options.units
string used in calculating cell size, can be degrees, radians, miles, or kilometers (optional, default 'kilometers'
)options.properties
Object passed to each hexagon or triangle of the grid (optional, default {}
)options.mask
Feature<Polygon>? if passed a Polygon or MultiPolygon, the grid Points will be created only inside itoptions.triangles
boolean whether to return as triangles instead of hexagons (optional, default false
)Examples
var bbox = [-96,31,-84,40];
var cellSide = 50;
var options = {units: 'miles'};
var hexgrid = turf.hexGrid(bbox, cellSide, options);
//addToMap
var addToMap = [hexgrid];
Returns FeatureCollection<Polygon> a hexagonal grid
