Interpret and digitalise areas and boundaries in an image quickly and easily
Marine Tools, or formerly known as Remote Sensor Object Based Image Analysis or ‘RSOBIA’, is a NEW extension to Maritime Toolbar for Esri ArcMap, which takes raster imagery and can interpret the data into geographic areas with similar statistical properties.
It digitises the areas and classifies the boundaries and areas seen in imagery (such as sidescan sonar and multi-beam backscatter) and creates a polygonised map of the results (e.g. areas of similar seafloor type). It supports Segmentation and Classification which are key techniques for image analysis, and gives quick, easy and repeatable results.
Works with all types of imagery data
Quick (e.g. 250mb image < 40 secs)
Divides the data into areas of similar appearance (segments)
Can use more than 3 data layers (no limit)
Each polygon has statistics for every image layer
Scale and level of detail defined by numeric parameters chosen by the user – providing either a high resolution interpretation or a more generalised solution
Repeatable and objective
Easy to install
Works with and compliments your existing GIS tools
No requirement for programming knowledge
Up to 50 individual tools from slope calculations to satellite images
“Colouring in” of polygons with attribute info (e.g. substrate type)
Access to other techniques and software e.g. Conservation planning (using Marxan, Ball, 2000) and Geomorphometry (TASSE, Lecour et al., 2017)
Without the tool, digitising images can be slow, subjective – dependent on the interpreter – and is non-repeatable. Using Marine Tools, segmentation of the results will provide straight-forward and objective polygons which are statistically calculated. Other tools available include a complete run wizard for Benthic Terrain Modeller, a Satellite Derived Bathymetry wizard and many surface derivatives such as slope, roughness, and numerical aspect to name just a few.
Delivered as a part of Maritime Toolbar, Marine Tools is compatible with ESRI ArcMap 10.1 to 10.8 making it integral to your workflow. ArcGIS advanced level licence is required together with the spatial analyst extension, but it currently is not compatible with ArcPro.
This is not a standard toolbar of ESRI as this extension has been created by OceanWise’ Licensed Partner Tim Le Bas and is maintained and supported by OceanWise as a collaborative project.
Tim Le Bas is a Senior Marine Mapping Scientist for the NOC and has been working in the marine environment, mapping the seafloor for over 30 years. The emergence of available GIS systems has allowed numerical and statistical interpretation techniques to be developed. Tim developed the Marine Tools software to work with GIS systems and reduce the time spent laboriously classifying marine images by hand. This process which could take hours, days or even weeks by hand, can now be done in minutes using Marine Tools.
