GradeIT: Road Grade Inference Tool
Apr 16, 2020, 18:00 PM
GradeIT is a modular Python package the leverages the United States Geological Survey's
Digital Elevation Model. GradeIT employs a two-dimensional interpolation to approximate
elevation at a point on a road from the nearest nodes in the model. Then, GradeIT
applies multiple filtering techniques to smooth the elevation profile to a realistic
road topology. Finally, road grade is derived from the elevation profile and returned
as the primary output.
