Hi, To my knowledge, there is nothing built in so you would have to build and maintain the spatial index yourself.
If you are only doing a distance query, you might consider keeping a column containing something like a geohash (http://en.wikipedia.org/wiki/Geohash) and then build a secondary index using that, so that you can efficiently pull features by proximity (read the limitations section on the wiki though. C-squares is a similar algorithm). You are not going to get close to the functionality offered by something like PostGIS, but you will be able to work around things like a proximity search while still handling huge data quite easily I would have thought. I have played with geohash and hbase but only for quick tests - nothing I can point at... Hope this helps, Tim On Sat, Jun 26, 2010 at 3:35 PM, Joe Stein <[email protected]> wrote: > Does HBase have any GEO GIS support in being able to calculate and > conditional on distance for the long/lat condition entered? > > If not has anyone done this with HBase even if not built in somewhere? > > /* > Joe Stein > http://www.linkedin.com/in/charmalloc > Twitter: @allthingshadoop > */ >
