Geo-Indexing - Richard Parker

Indexing and accessing points on the Earth's Surface

Relational databases are poor. • Of course one can store the data in a relational database, but finding the nearest ones is not that easy for the DB system. • Without any special coding, we would need to compute a function of every point in the database (distance to target), involving a full table scan. • It is possible to do better of course, but only by essentially writing the search by hand.
