I built DudeMap because working with geospatial data online has always been frustrating. Most tools are slow, limited, or require heavy desktop GIS software. I wanted a fast, modern, and free map viewer that lets anyone upload GeoJSON, FlatGeobuf, Shapefiles, KML, GPX, or CSV and visualize them instantly in the browser. The goal is simple: make geospatial visualization accessible, fast, and effortless—even for large datasets.
