OGC Moving Features Access. Version 1.0.

Abstract

This document defines Moving Features Access, i.e., access methods to moving feature data for retrieving feature attributes, information on a relation between a trajectory object and one or more geometry objects, and information on a relation between two trajectory objects from a database storing trajectory data of moving features. Abstract methods of accessing moving features data are defined in ISO 19141:2008 (Geographic information - Schema for moving features) [ISO 19141:2008]. However, the methods are insufficient to access a database storing moving feature data from multiple sources. If implementations for access to moving features data using various programming languages or protocols (e.g., SQL, Java, and HTTP) are developed without any standards, these implementations might be inconsistent with each other, resulting in poor interoperability. Therefore, methods to access a database storing moving feature data are necessary to improve interoperability. Applications using moving feature data, typically representing vehicles or pedestrians, are rapidly increasing. Innovative applications are expected to require the overlay and integration of moving feature data from different sources to create greater social and business value. Moreover, systems relying on single-source moving feature data are now evolving into more integrated systems. Integration of moving feature data from different sources is a key to developing more innovative and advanced applications. Moving Features Access ensures better data exchange by handling and integrating moving feature data to broaden the market for geo-spatial information such as Geospatial Big Data Analysis. OGC 14-083r2 (OGC® Moving Features Encoding Part I: XML Core) [OGC 14-083r2] and OGC 14-084r2 (OGC® Moving Features Encoding Extension: Simple Comma Separated Values (CSV)) [OGC 14-084r2] are existing implementation standards. Moving Features Access uses these standards to encode moving features.
