Estimate and fact-check the maximum number of people that can stand in a given area by drawing polygons on a map and applying reasonable crowd-density assumptions. Live site: https://www.mapchecking.com/
The app is frontend-only (static), built with Vue.js 3 and Vite. Static site generation (SSR) is handled with vite-ssg.
- Draw a polygon to outline an area of interest.
- See area (m² / sqm) and capacity estimates based on chosen crowd densities.
- Tweak density presets (e.g., 0.5–4.5 people/m²) to compare scenarios.
- Share a permalink to a specific map view / shape set
- Fast, modern UI built with Vue 3 + Vite + Tailwind CSS.
The app relies on Google Maps JavaScript API. The API key is set in ./src/config.json.
