Road Network Mask

Overview

The Road Network Mask node generates a map where all white pixels represent either a street or a parking lot.

Detailed Explanation

We use OpenStreetMap data to generate this mask containing the roads and parking lots. We generally do not include small service ways. However, to avoid gaps between the road network and parking lots we do add service ways connected to parking lots to the road network.
Being on a road or parking lot means that the mask contains a 1 at this location and the opposite is represented by a 0.

Settings

While the node itself doesn't feature any parameters we can still configure this node in the global settings: Project Settings > holoride > Road Network Mask.

Use Cases

Distance Transform Example

One common use case for this node is in combination with the Distance Transform node. This can be used in a lot of cases including feeding it into Texture Layers for texturing or spawning objects a certain distance away from the road network.
