Building Footprint Drawer

Click on canvas to add points and draw a building footprint.

The Building Footprint Drawer tool enables users to manually draw and outline building footprints on a digital canvas, generating precise GeoJSON data for spatial analysis or mapping projects. This tool is designed for urban planners, GIS experts, and researchers who need to create or edit building boundaries for accurate geospatial datasets. Users simply click to mark points on the canvas, utilize functions like undo or clear, and export their finished footprint shapes for further use.

How to use this tool?

Complete Guide: Using the Building Footprint Drawer Tool

  1. Getting Started
    • The tool displays a large canvas area for drawing building footprints, with several control buttons beneath it.
  2. Drawing a Footprint
    • Click anywhere within the blue canvas to place the first vertex (corner) of the building footprint.
    • Continue clicking additional points to outline the shape of the building. Each click adds a new vertex/point to your shape.
  3. Closing the Shape
    • Once all corners are placed, click the Close Shape button to finish your footprint. This will automatically connect the last point to the first point to complete the polygon.
  4. Editing Points
    • If you make a mistake, click Undo Point to remove the most recently placed vertex.
    • To start over, click Clear All to erase all points and shapes from the canvas.
  5. Exporting Your Work
    • Once your building footprint is finished, click Export GeoJSON. This will allow you to download the shape as a GeoJSON file for use in GIS or mapping software.
  6. Snapping Points
    • The Snap button toggles snapping on or off (shows as "Snap: Off" or "Snap: On"). When enabled, points you place will attempt to align precisely with existing vertices or gridlines, useful for creating accurate rectangular or orthogonal shapes.
  7. Tips
    • Follow the notification below the buttons for tooltips and instructions.
    • Ensure the shape is closed properly before exporting for best results.

Summary of Buttons

  • Close Shape - Finish and close your polygon shape.
  • Undo Point - Remove the last point you added.
  • Clear All - Remove all points and reset the canvas.
  • Export GeoJSON - Export your completed shape as a GeoJSON file.
  • Snap: On/Off - Enable or disable snapping for precise point placement.
