The Grasbrook Functional Scope provides a mapbox based application to support functional planning for a new urban neighborhood. Users will be able to simulate pedestrian flows, stormwater runoffs, traffic noise propagation, sun exposure and wind speeds. With more modules to come.

Explore interrelationships of different result layers. Example: In which areas are many pedestrians exposed to high traffic noise?

The buildings displayed on the map are stacked extrusions of 3 geojson layers. Please provide a groundfloor.json, upperfloor.json and rooftop.json via your CityPyo user.

Following properties can provided per Feature. Mandatory for the visualization to work are city_scope_id and land_use_detailed_type. Upperfloor features must contain a float value for building_height Rooftop features must contain float values for building_height and additional_roof_height

{"building_id": "G03", "land_use_detailed_type": "residential", "building_height": 44.3, "additional_roof_height": 47.5, "area_planning_type": "building", "floor_area": 341.8590000002878, "city_scope_id": "B-03-1"}

The open spaces displayed are read from a spaces.json provided by your CityPyo user. Following properties can provided per Feature. Mandatory for the visualization to work are city_scope_id and land_use_detailed_type.

"properties": {"area_planning_type": "specialUseArea", "land_use_general_type": "privateOS", "land_use_detailed_type": "schoolOutdoorArea", "floor_area": 2774.420039495546, "city_scope_id": "S-283"}

Provide result files for the ABM results and Noise results (currently static). Please ask maintainers for example files.
