Implementing Geospatial Web Services Using Service Oriented Architecture and Nosql Solutions

Today a huge amount of geospatial data is being created, collected and used more than ever before. The ever increasing observations and measurements of geosensor networks, satellite imageries, point clouds from laser scanning, geospatial data of Location Based Services (LBS) and location-based social networks has become a serious challenge for data management and analysis systems. Traditionally, Relational Database Management Systems (RDBMS) were used to manage and to some extent analyse the geospatial data. Nowadays these systems can be used in many scenarios but there are some situations when using these systems may not provide the required efficiency and effectiveness. In these situations, NoSQL solutions can provide the efficiency necessary for applications using geospatial data. At the other hand, In order to provide full access to geospatial data, they have to be published as standard-based resources over the Web. In other words, custodians of geospatial data have to publish standard-based services to serve geospatial resources in interoperable and platform-independent manner. In this regard, geospatial services must be designed and developed using Service Orientation Architecture (SOA) to provide full interoperability for diverse kinds of end users. But in this context, nature of geospatial data prevents full potential of using SOA in GIS world. This paper proposes an approach to overcome the mentioned issue using SOA and NoSQL solutions.
