The field of parking lots [outlined in red and green] spread throughout downtown Rochester prompted a Grasshopper [GH] exploration on their relationships to two corridors: the abandoned subway tunnel [shorter segment] and the Genesee River [oriented north-south].

Based on the size of each parking lot [green outlines are parking garages], points are positioned from the center of each shape while its Z-value is a factor of each individual footprint.

A modified voronoi surface creates a terrain based on parking lot sizes in top and perspective views.

After creating the 3D landform, I took perpendicular sections along each corridor to describe its relationship to the distribution of parking area.  The first set of 3 images describes the conditions along the abandoned subway tunnel.

Flattening these sections would probably help illustrate more clearly the variation in area distribution or parking [potential usable] availability along the corridor.  That will be for another time.

The following 3 images are of sections along the Genesee River.
