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.
