ESRI Geometric Symbols from ESRI, Inc. is a free geometric dingbat font built from circles, polygons, squares, and crossed frameworks. The signs use firm, even outlines and centered solid forms, giving the collection the measured look of cartographic keys or technical notation rather than conventional lettering.
Map legends are its clearest destination, but the same compact constructions also suit wayfinding signage, educational diagrams, technical publishing, and interface graphics, where simple shapes can identify categories, locations, or functions at a glance. Across these uses, repeated geometry turns information into a coherent icon system.
