Description

This ticket tracks the addition of read support for ESRI .sbn spatial index.

A new file, sbnsearch.c aimed at being integrated in shapelib (no dependency to CPL), is added, and it is used into ogrshapelayer.

Credits belong to Joel Lawhead, Marc Pfister and Francisco for the hard work of reverse-engineering the .sbn format and interpreting the meaning of the spatial bins and the tree structure. Links :

Milestone: 1.10.2
Resolution: fixed
Status: newclosed

From the documentation http://www.gdal.org/drv_shapefile.html

"Starting with OGR 1.10, it can also use the ESRI spatial index files (.sbn / .sbx), but writing them is not supported currently."

This ticket is about read support for .sbn which is clearly implemented.
