Advances in fusion of big geospatial data

Geospatial fusion provides methods to get the most value from geospatial information. A previous OGC study on geospatial fusion identified recommendations for observation fusion, feature fusion and decision fusion. Many of the recommendations were taken up in OGC Innovation Program and are now present in the OGC Standards baseline. This paper reviews the remaining recommendations from the previous study. This paper also examines the affect of recent information technology trends on geospatial fusion including big data, cloud technologies, linked data and new sources of geospatial observations.
