This put up is a continuation of Spatial Index: Grid Systems the place we are going to set the muse for tessellation and head into the main points of Uber H3
Tessellation or tiling is the method of overlaying/dividing an area into smaller, non-overlapping shapes that match collectively completely with out gaps or overlaps. In spatial indexing, tessellation is used to interrupt down the Earth’s floor into manageable items for environment friendly knowledge storage, querying, and evaluation.
The rationale behind why a geographical grid system (Tessellation system) is important: The true world is cluttered with numerous geographical parts, each pure and man-made, none of which comply with any constant construction. To carry out geographic algorithms or analyses on it, we want a extra summary kind.
Maps are an excellent begin and are the most typical abstraction, with which most individuals are acquainted. Nevertheless, maps nonetheless include all kinds of inconsistencies. This requires a grid system, which takes the cluttered geographic house and supplies a extra clear and structured mathematical house, making it a lot simpler to carry out computations and queries.
