Résumé:
The large volume of georeferenced information produced in the Web 2.0, specially
given the popularity of collection devices, such as smartphones, GPS and cameras, has
increased the demand for new techniques for data storage. In this context, NoSQL systems
have been a promising approach. The need to bring together the entire spectrum of
georeferenced information takes us to the traditional problem of interoperability between
SQL spatial databases and NoSQL systems. In other words, the problem addressed is the
interoperability of spatial data from heterogeneous data sources. This work proposes a solution
for the interoperability of spatial data stored in SQL databases and NoSQL systems
using OGC interoperability services such as WMS and WFS. Experiments conducted using
the spatial database PostgreSQL-PostGIS and NoSQL systems such as CouchDB-GeoCouch
and MongoDB demonstrated that it is possible to submit queries using the same syntax for
SQL spatial databases and NoSQL systems in a simple and transparent manner for the user's
application.
