How to create a flexible Travel Distance Overlay
For calculations regarding the availability and accessibility of certain objects, areas, or services, a Travel Distance Overlay can be used to calculate not just the linear distance but from which places such a feature can actually be reached within a journey of a given length. However, there can be great variety in all aspects of such a journey. To make it easier to configure this calculation, it's possible to make the Travel Distance Overlay reference calculated Grid Overlays indicating the destinations and potential routes.
How to create a flexible Travel Distance Overlay:
- Create a Combo Overlay to determine the destinations
- Create a Combo Overlay to determine the traversable routes
- Create a Travel Distance Overlay with the following configuration:
Destinations: Set to the destinations Grid Overlay
Traversables: Set to the traversable routes Grid Overlay. - Recalculate if applicable
