Grid (spatial index)

In the context of a spatial index, a grid or mesh is a regular[citation needed] tessellation of a manifold or 2-D surface that divides it into a series of contiguous cells, which can then be assigned unique identifiers and used for spatial indexing purposes. A wide variety of such grids have been proposed or are currently in use, including grids based on…
