Swath Separation Image resolution

By NGP Standards and Specifications

This revision updates the Swath Separation Image spatial resolution (pixel dimension) to match that of the revised Maximum Surface Height Raster requirement. The new resolution will be twice the bare-earth Digital Elevation Model deliverable's cell size.

Current requirement:

In LBS 2022 rev. A: Deliverables: Swath Separation Images: 

Spatial extent and coordinate reference system: 

  • Spatial resolution (pixel dimension) of the images shall be no greater than 4 times the Nominal Pulse Spacing (4 x NPS) in the project’s linear unit (meters or feet).

Change to: 

Spatial extent and coordinate reference system: 

  • Spatial resolution (pixel dimension) of the images shall be twice (2x) the bare-earth DEM deliverable cell size in the project’s linear unit (meters or feet).
