Loading Basemaps and Overlays

SonarWiz provides the ability to display multiple reference maps and images in the main view in addition to the sonar mosaic. These maps can be used to provide a visual reference during and after a survey, and also to enhance the quality of the data prior to incorporation into reports and presentations. A Basemap is typically a nautical chart, satellite image or bathymetry raster. Basemaps go under (behind) the sonar data display layer. Overlays are usually vector layers (lines and polygons) that are typically presented over (on top of) the sonar data display layer.
