![]() ĭissolve has various applications in cartography and GIS. ![]() Giving linear features a dotted appearance or connecting linked line segments into one larger line segment in a GIS is also considered a dissolve operation. Thus, using the dissolve operator on multiple polygons with a common value will yield one new polygon, combining the dimensions of the original, dissolved polygons. In choropleth maps, the dissolve operation eliminates the boundaries of enumeration units with a common value, depicting a much larger area holding the same common value. In GIS, dissolve is one of the Data Management tools used for generalizing features. ![]() Dissolve is an application of the conceptual operators that aggregates features often referred to as 'Merge' or 'Amalgamation.' It is a process in which a new map feature is created by merging adjacent polygons, lines, or regions that have a common value for a specified attribute.
