Geophile, Inc. develops, licenses and supports Geophile, an extensible spatial index written in C++.

You need Geophile if you are writing an application with the following characteristics:

• Application needs to carry out fast spatial searches, such as "find the objects overlapping this region", or "find the object nearest this point".
• Application manipulates spatial objects (points, boxes, spheres, polygons, parametric surfaces, etc.).
• Application is being developed in C or C++.

Geophile adds fast spatial search capabilities to your application, no matter what kind of spatial objects you have, in any number of dimensions, whether your data resides in virtual memory, on disk, in a relational database, or in an object-oriented database.
