What is the Point Grid Generator?
The Point Grid Generator creates a regular orthogonal grid of evenly-spaced points within a bounding box you specify. You can draw the bounding box on the map or enter coordinates, then set the spacing between points in kilometres, miles, or degrees. The output is a GeoJSON, KML, or GPX file of point features.
Regular point grids are a standard tool in environmental sampling, geostatistics, and survey design. They ensure systematic coverage of a study area with a fixed density, avoiding the clustering that random sampling can introduce.
Common use cases
Environmental and soil surveys
Generate sampling locations at regular intervals across a study area to ensure systematic coverage for soil, water, or vegetation surveys.
Kriging interpolation input
Create a regular grid of query points to feed into a kriging or IDW interpolation model, then populate with interpolated values.
Coverage and accessibility analysis
Generate a grid of potential locations and calculate travel times or distances from each point to assess coverage of a service.
Remote sensing validation
Create systematically distributed ground-truth sample points for validating land cover classification from satellite imagery.
Frequently asked questions
What units can I use for the grid spacing?
You can specify the spacing in kilometres, miles, or decimal degrees. The tool converts between units internally. For most GIS applications, kilometres or degrees are the most intuitive choice.
What coordinate system are the generated points in?
All generated points use WGS 84 geographic coordinates (longitude, latitude). The grid is regular in geographic space, which means the physical spacing in metres varies slightly with latitude — points near the poles are physically closer together than points near the equator for the same degree spacing.
Can I clip the grid to a polygon boundary?
This tool generates a grid within a rectangular bounding box. To clip the grid to an irregular polygon boundary, download the GeoJSON output and use the Clip tool on this site to intersect it with your study area polygon.
How many points can I generate?
The number of points is determined by the bounding box area divided by the grid spacing squared. Very small spacing values over a large bounding box can generate millions of points, which may be slow to process in the browser. Start with a coarser grid and refine as needed.
