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

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

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

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

python3 add-polygon-heights.py

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

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.
