centroids, plural;
  1. The center of mass of a geometric object of uniform density

  1. (centroid) the center of mass of an object of uniform density
  2. In geometry, the centroid, geometric center, or barycenter of a plane figure or two-dimensional shape X is the intersection of all straight lines that divide X into two parts of equal moment about the line. Informally, it is the "average" (arithmetic mean) of all points of X. ...
  3. (centroid) The point at the centre of any shape, sometimes called centre of area or centre of volume. For a triangle, the centroid is the point at which the medians intersect. The co-ordinates of the centroid are the average (arithmetic mean) of the co-ordinates of all the points of the shape. ...
  4. (centroid) The term given to the center of an area, region, or polygon. In the case of irregularly shaped polygons, the centroid is derived mathematically and is weighted to approximate a sort of `center of gravity. ...
  5. (Centroid) The point that may be considered the center of a one- or two-dimensional figure.
  6. (Centroid) A point at the geometric centre of a polygon. This can be used to represent a polygon as a point.
  7. (CENTROID) (input-data-set, output-data-set, list-of-id-variables);
  8. (Centroid) A point feature centrally located within, and used to identify, an area feature.
  9. (Centroid) A point that is linked to a TAZ that loads traffic onto the network
  10. (Centroid) As determined by the local the search engines, the centroid is the very center of a neighborhood or metropolitan area. A business’ proximity to the centroid plays a role in where it ranks in the local search results; however there is debate on how important it is. ...
  11. (Centroid) I know it sounds like something you take for an upset stomach, but it actually means the geographical center of a city or town, as defined by Google. ...
  12. (Centroid) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.
  13. (Centroid) The average value of a group of objects in a cluster.
  14. (Centroid) The point of a triangle that is created by the intersection of its three medians. Sometimes referred to as the "center of gravity."
  15. (Centroid) The point of concurrency when it is inside the triangle.
  16. (centroid) A point whose coordinates are the average of an associated parts dimensions (central point).
  17. (centroid) The calculated geographic center of a region. Alternatively, a point in an enclosed area which is used to link boundary data to associated attribute information.
  18. (centroid) a term used for the multivariate mean scores in MANOVA.
  19. (centroid) that point about which the static moment of all the elements of area is equal to zero
  20. A centroid is a central point or logical collection point in a Renewable Energy Zone. Small generators will likely be dispersed throughout a REZ. The collector feeder lines from the generators will all converge at the centroid that connects to the bulk transmission grid.
  21. In reference to demographics: geographic points marking the approximate centers of populations within the 260,000 block groups and enumeration districts in the U.S. ...
