Показать описание
This tutorial shows you how to use the OpenRouteService Distance Matrix API to locate the nearest health facility for many locations.

We will take 2 layers for Washington DC - one with points representing addresses and another with points representing mental health facilities - and find out the facility with the least travel distance from each address using the OpenRouteService (ORS) Distance Matrix API.

Hello Ujaval! Great video! I'm trying to verify the distances using 1 origin and multiple destinations.
The weird part is that im getting a 403 error "Forbidden" even with a valid API key.
Do you have any idea what might cause this error?

Hii Ujjawal, i am a phd scholar working on Urban green spaces in Delhi. I want to differentiate agriculture landuse from other green spaces. I guess this will need phenology as input. Do you have any idea how to do it? Thank you😊
