The double geobase is presented as a projection of the geobase's filamentary network that approximately simulates the boundaries of sidewalks and curbs. The [geobase poles] (/city-of-montreal/geobase-pole), a punctual representation of the left and right sides of segmented sections of the road network, are also available on the portal.
