A Quadtree for Global Information Storage by Waldo Tobler and Zi-tan Chen QUADTREES The hierarchical data structure known as a quadtree has advantages for geographic data storage.  ...  Adaption to an ellipsoid is straightforward. It is not necessary to use the idea of a map projection at all in a computerized geographic information system.  ...

Location-aware alert system for mobile devices

Philip Sibley, Ramona Trestian, Gabriel-Miro Muntean

We build a prototype system, using free and open source software, to deliver alerts to mobile devices within a predetermined geographical area.  ...  In this paper we propose a novel algorithm which makes use of spatial indices to determine if a mobile is located within a predefined polygon shape area.  ...  They suggest the use of adaptive maps to display the temporal data, and the use of meshing techniques to display some of the data, where there is little likelihood of change (road/rivers etc.).  ...
