Title
GEOCOUCH: A SPATIAL INDEX FOR COUCHDB
Abstract
Apache CouchDB is a non-relational so-called document-oriented database and
therefore part of the NoSql movement. It has an RESTful API and thus a good
match for web-application. On top of that it has an robust storage system
which is essential for huge geodata sets.
Though it currently doesn't support spatial indexing. GeoCouch tries to fill
that gap as PostGIS did for PostgreSql. The implemetation is not based on an
approximated solution like Geohashes, but an R-Tree.
At last year's FOSS4G I gave an introduction into CouchDB and the possiblity
for storing geodata. This year it will contain only a short introduction into
CouchDB for people not familiar with this technonolgy, but focus on the
implementation and usage of such an spatial index.
