GeoJSON Indoor Tools

Quick GeoJSON tools for editing and modifying geojson data, focusing on indoor features.

Available Scripts

• Features inside area
• Add polygons heights
• Rooms to walls
• Add doors to rooms

Features inside area

Removes any feature that is outside of a polygon. Great for grabbing an area indoor data generated by other services.

python3 features-inside-area.py

Add polygons heights

Adds multiple properties to polygons: level, height, base_height and a random color.

python3 add-polygon-heights.py

Rooms to walls

Create walls for any polygon room. You can adjust the wall thickness with zeta. It also sets height so walls are differentiable from the original room polygon.

python3 rooms-to-walls.py

Add doors to rooms

Cut out rooms doors from their polygons. Doors are geometrically points near their walls.

Important notes:

• For assigning a door to a room, the door should have door: yes tag and room_id:

    {
      "type": "Feature",
      "properties": {
        "room_id": "main",
        "tags": {
          "door": "yes"
        }
      },
      "geometry": {
        "coordinates": [~],
        "type": "Point"
      }
    }
  

  The room must have an id and a room indoor tag:

    {
      "type": "Feature",
      "properties": {
        "id": "main",
        "tags": {
          "indoor": "room"
        }
      },
      "geometry": {
        "coordinates": [
          [~]
        ],
        "type": "Polygon"
       }
    }
  

• Door points must be near their wall but not necessarily on the wall line. The algorithm will find the nearest wall.
• Multiple doors for a single wall is NOT supported.
• Set include_lintel to True if you want the lintels to be included in the final feature collection. You can adjust their properties with lintel_properties.
• circle_radius_cm indirectly defines the width of the doors. Setting it to a big number will cause problems in finding the correct wall for a door.
