Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
@turf/square-grid
Advanced tools
@turf/square-grid is a module from the Turf.js library that allows you to create a grid of squares within a bounding box. This can be useful for various geospatial analyses, such as dividing a region into smaller areas for detailed study or visualization.
Create a square grid
This feature allows you to create a grid of squares within a specified bounding box. The `bbox` parameter defines the bounding box, `cellSide` specifies the side length of each square, and `options` can include units of measurement.
const turf = require('@turf/turf');
const bbox = [-95, 30, -85, 40];
const cellSide = 50;
const options = { units: 'miles' };
const squareGrid = turf.squareGrid(bbox, cellSide, options);
console.log(squareGrid);
Leaflet is a popular open-source JavaScript library for mobile-friendly interactive maps. While it does not specifically create square grids, it offers extensive functionalities for creating and manipulating map layers, including grid layers.
D3-geo is a module of D3.js that provides geographic projections, shapes, and utilities. It can be used to create various types of geographic visualizations, including grids, but requires more manual setup compared to @turf/square-grid.
GeoTIFF is a library for reading and writing GeoTIFF files. While it does not create square grids, it can be used to manipulate geospatial raster data, which can be divided into grids for analysis.
Creates a square grid from a bounding box.
Parameters
bbox
Array<number> extent in [minX, minY, maxX, maxY] ordercellSide
number of each cell, in unitsoptions
Object Optional parameters (optional, default {}
)
options.units
string used in calculating cellSide, can be degrees,
radians, miles, or kilometers (optional, default 'kilometers'
)options.mask
Feature<(Polygon | MultiPolygon)>? if passed a Polygon or MultiPolygon,
the grid Points will be created only inside itoptions.properties
Object passed to each point of the grid (optional, default {}
)Examples
var bbox = [-95, 30 ,-85, 40];
var cellSide = 50;
var options = {units: 'miles'};
var squareGrid = turf.squareGrid(bbox, cellSide, options);
//addToMap
var addToMap = [squareGrid]
Returns FeatureCollection<Polygon> grid a grid of polygons
