This repository contains code to generate library isochrones from Open Route Service.
An isochrone is a line on a map that connects points that can be reached within a certain limit (e.g. time or distance). In this case, the isochrones are generated from points on the map that represent libraries.
Isochrones are useful for understanding the accessibility of a location as well as understanding the people within those limits. It differs from more crude measures of accessibility such as the 'straight line' distance between two points. In the case of libraries, and other public service points, isochrones can be useful for defining catchment areas, understanding the population within those areas, and planning services.
Scripts for different library data sources are stored in the scripts folder. The scripts are written in Python and use the openrouteservice library to generate isochrones.
| Script | Description |
