This dataset includes a series of GIS layers produced from the preliminary versions of the seabed bathymetry survey work undertaken off the west coast of Lewis in 2011. Bathymetric data collected during the survey has been converted for use in ARCGIS and several products are derived from this original dataset.

| Data Dictionary | Original bathymetry is tide corrected and cleaned. The ASCII ArcGrid output is converted to raster (geotiff format). ESRI Spatial analyst tools used to created additional products (Hillshade, aspect, slope and rugosity). These are combined into a layer package for use with ArcGIS and a KMZ package for use with Google Earth. Please note that an artefact can be seen in the ArcGIS versions of the 2011 survey data due to a technical error in the multibeam offsets. |
