Spatial Index - Framework for Developing Spatial Indices
Sponsors
<-- Free GIS Software & Resources
Spatial Index - This package provides a general framework for developing spatial indices. Currently it defines generic interfaces, provides simple main memory and disk based storage managers and a robust implementation of an R*-tree, an MVR-tree and a TPR-tree. For more information please read the browser:spatialindex/trunk/README#latest file. In addition, the library includes a 3-dimensional R-tree visualization plug-in (example image below; requires Java3D runtime). This library is free software published under the GNU Lesser General Public License. You may copy, modify and use freely.
