Description: MATLAB toolbox RivMAP (River Morphodynamics from Analysis of Planforms). RivMAP provides tools for quantifying static planform geometries from binary channel masks including centerline and bankline extractions, widths, lengths, angles, and curvatures. It also provides functions to measure changes in time, including centerline and bankline migrated areas, areas of erosion and accretion, and cutoff identification, and creates reference grids for mapping these changes. No graphical user interface (GUI) is currently offered, but functions are written intuitively and well commented for ease of customization and application to specific research questions. RivMAP relies primarily on MATLAB’s built‐in image‐processing morphological operations, such as erosion, dilation, hole‐filling, skeletonization, and distance transforms, to efficiently compute relevant outputs from channel masks. While most of the tools included in RivMAP may be also found in other packages, some of its tools offer innovative solutions to image‐based processing problems. The construction of a grid for space‐time mapping (section 4.5) a novel method for mapping high temporal resolution planform changes. RivMAP also contains a function to stitch together georeferenced imagery so that results may be recombined for postprocessing. The following sections describe the technical details of RivMAP functions. A link to download RivMAP and a demo with data from the R6 subregion of the Ucayali River are provided in the acknowledgements.
