(Best paper award winner) Scalable Network Distance Browsing in Spatial Databases (2009)
Hanan Samet, Jagan Sankaranarayanan, Houman Alborzi
An algorithm is presented for finding the k nearest neighbors in a spatial network in a best-first manner using network distance. The algorithm is based on precomputing the shortest paths between all...

Geometric Issues in Spatial Indexing (2006)
We address a number of geometric issues in spatial indexes. One area of interest is spherical data. Two main examples are the locations of stars in the sky and geodesic data. The first part of this...

Efficient query processing on spatial networks (2005)
Jagan Sankaranarayanan, Houman Alborzi, Hanan Samet
A framework for determining the shortest path and the distance between every pair of vertices on a spatial network is presented. The framework, termed SILC, uses path coherence between the shortest...
