Boost.Geometry R-tree - speeding up geographical computation.

Learn how to accelerate geographical computation with Boost Geometry's R-tree, a parameterized spatial index for storing and querying points, boxes, and segments, ideal for applications like routing, location-based services, and GIS.

Key takeaways
  • The Boost Geometry R-tree is a spatial index that can be used for geographic computation.
  • The R-tree is parameterized and can store various types, including points, boxes, and segments.
  • There are three balancing algorithms: linear, quadratic, and R-star tree versions.
  • The size of a node is defined by the page size, and the number of elements stored in a node affects the time spent on creating the R-tree.
  • The R-tree is self-balanced and can be created using different algorithms, including packing and bulk insertion.
  • The self-balancing algorithm tries to maintain a balance between the number of elements in each node.
  • The R-tree can be used for searching and KNN (k-nearest neighbors) searching, and it is used by MySQL for GIS features.
  • The Boost Geometry library also provides primitives, algorithms, and data structures for geographic computation.
  • The R-tree can be used with different data types, such as Cartesian points, boxes, or segments, and it supports the use of different spheroids and coordinates systems.
  • The Boost Geometry library is used by many organizations, including Oracle.
  • The R-tree is used for spatial searching and KNN searching, which can be used in many applications, such as routing, pathfinding, and location-based services.
  • The R-tree can be used with different query types, including range queries, nearest neighbor queries, and spatial joins.
  • The R-tree is scalable and can handle large datasets.
  • The R-tree can be used in many applications, including geographic information systems, computer-aided design, and video games.
