GovHack 2019 Entry: Greenway - Greater Sydney's Cool and Green Routes

Greenway

GovHack 2019 Entry - Greater Sydney's Cool and Green Routes - https://hackerspace.govhack.org/projects/greenway

Demo: https://www.alantgeo.com.au/demos/govhack19-greenway/ (since this was just a working prototype, the routing services have now been turned off but you can still explore the demo)

Normal Pedestrian Routing

The shortest route, but goes through an urbarn heat island.

Cool Pedestrian Routing

The longer route, but bypassed an urban heat island.

Implementation

Front End Web App

Built using Vue/Vuetify, inside www run:

• yarn install
• yarn run serve

Routing Engine

• Implementing using OSRM we have tweaking the pedestrian routing profile in profiles/footcool.lua.
• Using a raster dataset of the NSW Urban Heat Island dataset - https://datasets.seed.nsw.gov.au/dataset/nsw-urban-heat-island-to-modified-mesh-block-2016. This is loaded into the profile the same way as a terrain is loaded in to avoid hilly routes.

Data Processing

All the scripts are in the Makefile, including:

• Build OSRM routing data
• Process SEED open data into Vector Tiles for visualisation in the web app.
