NoSQL-GeoServices: um framework para interoperabilidade de dados geográficos armazenados em sistemas NoSQL.

Abstract

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.
