HIPS and SIPS™ 10 introduces
Variable Resolution (VR) Surfaces
A VR Surface is a digital elevation model (DEM) where the grid resolution varies in different areas to better reflect the shape and details of the seafloor. This allows a more dynamic and continuous model, quickly adapting to different data densities, leading to workflow efficiencies and improved data management and analysis.
Interaction with a VR Surface is a very fast process which seamlessly transitions between display scales, dynamically loading and unloading points as you zoom in further.
Resolution variability can be based on depth range or data density. Using depth range, the user will assign resolutions to a series of depth ranges. Typically, data from deep areas with fewer samples will be assigned a coarser resolution, with the assigned resolution becoming finer in shallower depths where more data is present. A slightly different approach is taken with the density technique. The user will define a target density value for each node and the algorithm will choose the resolution for each area that best meets that criteria. This removes any a priori assumptions about resolution by the user, producing a continuous model with an optimal resolution for each area, regardless of depth or data density.
A single VR surface can be contoured in a single pass. This saves a great deal of time as traditionally, multiple surfaces would need to be generated and contoured. These contours would then require stitching together into single continuous line features and related depth areas.
Storage of such large datasets is accomplished through the CARIS Spatial Archive (CSAR™) Framework. It acts as a single file storage format for gridded, point cloud, and variable resolution data. It is scalable to billions of grid nodes and terabytes of data. This format is a very efficient way of storing and visualizing huge volumes of data.
