RiverREM

RiverREM is a Python package developed for the automated generation of river relative elevation models (REM) and their corresponding visualizations. It operates by taking a standard digital elevation model (DEM) as its primary input. The package then utilizes the OpenStreetMap API to retrieve accurate river centerline geometries that span the extent of the provided DEM. This integration allows for the precise mapping of river networks within the topographical data.

A key feature of RiverREM is its sophisticated approach to elevation interpolation. The package employs a specialized sampling scheme that considers both the raster resolution of the DEM and the sinuosity of the rivers. This method is crucial for producing high-resolution visualizations that are free from common interpolation artifacts, ensuring the output is visually striking and scientifically accurate. Users can generate these detailed visualizations directly, without the need for extensive manual post-processing steps.

Beyond REM generation, RiverREM also includes a helpful helper class specifically designed for creating general DEM raster visualizations. This additional functionality enhances the package's utility for various terrain analysis and hydrology applications, making it a versatile tool for researchers and practitioners working with riverine landscapes.
