Comprehensive, mathematically rigorous guides on distance calculations, map radius buffers, elevation datums, US boundary jurisdiction, and client-side GIS analysis.
A definitive guide on drawing 5-mile, 10-mile, or custom distance circles around addresses on Google Maps, overcoming Web Mercator distortion, and using free dedicated radius tools.
Google Maps does not feature a native one-click "draw radius" button on its consumer mobile or desktop app. To draw a radius on Google Maps, you must either create a custom map in Google My Maps and import a generated KML circle file, or use dedicated free web tools like the GeoMap Suite Radius Tool. With GeoMap Suite, you simply type an address, specify a distance in miles or kilometers, and instantly visualize geodesic radius circles with zero setup.
