We’re excited about this handy new feature: From now on, you can optionally return the population count for each isochrone you’re calculating. This is an imperative step for inclusive reachability analysis.
The dataset, which makes this possible, is published by the European Commission in their Global Human Settlement Program. It features 250 m x 250 m cell size across the globe and is the finest grained dataset of its kind.
To access this feature in runtime you have to specify it as attribute in the isochrone request:
https://api.openrouteservice.org/isochrones?api_key=your-api-key&locations=8.34234%2C48.23424&profile=driving-car&range=600%2C%201800&attributes=total_pop
This query will return:
"properties":{"group_index":0,
"value":600,
"center":[8.34234,48.23424],
"total_pop":8373,"total_area_km":43.9361
},...If you have any suggestions on including other global open datasets, feel free to drop us a note via @twitter
