Abstract: SmartDissolve is a polygon aggregation tool developed in the frame of the Global Human Settlement Layer (GHSL) project and it is being used to dissolve polygons setting an areal threshold. SmartDissolve is a tool that handles minimum mapping unit, resolution mismatch between layers, or spatial uncertainty problems in GISc. This tool automatically dissolves polygons below a threshold area, updating fields’ values. The toolbox allows to select the ordering of polygon analysis (i.e. from the smallest to the largest area, vice versa, or order of IDs), different dissolve rules (i.e. with smallest, largest, or maximum-border-share adjacent polygon, minimum total perimeter or maximum compactness) and different field updating operations (i.e. sum, mean or text concatenation). The software is available as toolbox for ArcGIS 10.X, a standalone command line tool or a MATLAB function. More details about the algorithm, the method and its actual applications can be found in the paper in the Reference section. This guide provides instructions about installing and using the SmartDissolve toolbox for ArcGIS and the SmartDissolve command line tool on a Windows computer and the SmartDissolve MATLAB function in a MATLAB environment.
