LiteMap measures any site from satellite imagery, so you can skip the site visit. It's a self-hosted web app with zero dependencies and an OpenAPI 3.1 REST API.

LiteMap event layout

Highlights

  • Measure: distances with segment totals, plus areas in ft² and acres or m² and ha, with perimeter. Snapping and full undo.
  • To-scale objects: 46 built-in objects, including tents from 10×10 to 100×200 ft, stages, vehicles, trailers, containers, equipment, and courts. Each has a clearance setting for stakes and egress.
  • Site fit:
    • Will it fit? places the object where it has the most margin.
    • Largest fit finds the biggest size that still fits.
    • How many fit? packs a grid and draws the layout.
  • Upload your own objects: on-device AI cuts the object out of a photo and crops it. Click the object or drag a box around it, then set its real size or stretch it to exact dimensions.
  • Newest imagery: overlay Esri, Wayback, NAIP, 3-inch county aerials, NASA GIBS, or the SkyFi archive. Each source is ranked by its real capture date at your site. Optional sharpening and AI enhancement.
  • Annotate and share: pins, text boxes, freehand drawing, links, GeoJSON or CSV export, and static satellite snapshots.
  • Integrate: REST API with Swagger UI, API keys and CORS. An embeddable iframe can be driven with postMessage.

Measurements are quote-grade, not survey-grade: accuracy is limited by the imagery (typically 1–3 m). Verify critical clearances on site.
