In this application note, we will demonstrate how [[EM.Terrano]] can be used to analyze a very large urban canyon propagation scene using its ultrafast k-d tree based ray tracer. Specifically, we will construct a scene representing a portion of lower Manhattan, NY, with real-sized models of its buildings and terrain profile. The total size of the area is 1.3km × 1.2km, and it will be covered with a very large rectangular grid of receivers equally spaced with a uniform spacing of 5m. You can learn more about the basic procedure for setting up an propagation scene and running a SBR simulation in "[[EM.Terrano Tutorial Lesson 2: Analyzing An Outdoor Multipath Propagation Scene]]".

== An Overview of the SBR Method and k-d Tree Formalism ==

The figure below shows a part of lower Manhattan that will be modeled as a propagation for this project. The real-sized building models are imported from a STEP CAD file, while the terrain is imported from a digital elevation map (DEM) file.
