This latest extension ‘Object Based Image Analysis’ or ‘RSOBIA’ takes raster imagery and segments the data into geographic areas with similar statistical properties. It interprets the areas and boundaries seen in imagery (such as side scan sonar or multi-beam backscatter) and makes a polygonised map of the results.
This tool works with all types of imagery data and is quick and easy to use, drastically reducing the amount of time it takes to segment images and provides straight-forward, objective polygons which are statistically calculated.
With the emergence of GIS systems, data integration and fusion has allowed numerical and statistical interpretation techniques to be developed. This tool provides a quick and simple aid for classification within a GIS environment, thus supporting workflows.
RSOBIA is brought to market as a collaboration between OceanWise and their Licensed Partner Tim Le Bas, Senior Marine Habitat Scientist for the NOC.
