centroid

URL copied Share URL
  1. [spatial analysis] The geometric center or average location of a spatial feature. For line, polygon, or three-dimensional features, it is the center of mass (or center of gravity) and may fall inside the feature, as shown in the example image for a triangle, or outside the feature, as shown in the example image for a complex line. For multipoints, polylines, or polygons with multiple parts, it is computed using the weighted mean center of all feature parts. Media/G43191_Centroid-Illus_7-10.gif
