“…The initial development of FMMidwater was built on a research prototype (GeoZui4D) developed at the University of New Hampshire to investigate methods for interactively visualizing time varying geospatial data [Arsenault et al, 2004;Ware et al, 2001] [1] [2]. Water column data required a number of new visualization metaphors and export options beyond those used for bathymetry data, in order to address the geospatial and temporal aspects of the analysis, and to extract fully refracted and adjusted detections to fuse with seabed detections from the multibeam processing and visualization.…”

“…The Adelaide 3D GIS planning model (2007) is an example of a 3D GIS which provides 3D visualisations of social and environmental data within a 3D cityscape. Two other interesting applications are called GeoZui3D (Ware et al 2001) and VGIS (Köller, 1995). GeoZui3D is a 3D marine GIS that supports real-time input and draped imagery; while VGIS is an integrated global GIS and visual simulation system.…”

In this paper we present a unique hybrid visualization system for spatial data. Although some existing 3D GIS systems offer 2D views they are typically isolated from the 3D view in that they are presented in a separate window. Our system is a novel hybrid 2D/3D approach that seamlessly integrates 2D and 3D views of the same data. In our interface, multiple layers of information are continuously transformed between the 2D and 3D modes under the control of the user, directly over a base-terrain. In this way, our prototype system is able to depict 2D and 3D views within the same window. This has advantages, since 2D and 3D visualizations can each be easier to interpret in different contexts.In this work we develop this concept of a hybrid visualization by presenting a comprehensive set of capabilities within our distinctive system. These include new facilities such as: hybrid landmark, 3D point, and chart layers, the grouping of multiple hybrid layers, layer painting, the merging of layer controls and consistent zooming functionality.

“…Georeferenced tools for AUV's serve two primary purposes: monitoring the AUV while it is underwater, and analyzing science and engineering data after After vehicle recovery, GeoZui3D, developed at the University of New Hampshire's Center for Coastal and Ocean Mapping, provides a powerful 3D interface for reviewing captured data [66]. In 2005, a system for real-time 3D monitoring of ROV's and HOV's based on integrating DVLNAV with GeoZui3D was presented [35].…”

Lossy compression and real-time geovisualization for ultra-low bandwidth telemetry from untethered underwater vehicles

Oceanographic applications of robotics are as varied as the undersea environment itself. As underwater robotics moves toward the study of dynamic processes with multiple vehicles, there is an increasing need to distill large volumes of data from underwater vehicles and deliver it quickly to human operators. While tethered robots are able to communicate data to surface observers instantly, communicating discoveries is more difficult for untethered vehicles. The ocean imposes severe limitations on wireless communications; light is quickly absorbed by seawater, and tradeoffs between frequency, bitrate and environmental effects result in data rates for acoustic modems that are routinely as low as tens of bits per second. These data rates usually limit telemetry to state and health information, to the exclusion of mission-specific science data.In this thesis, I present a system designed for communicating and presenting science telemetry from untethered underwater vehicles to surface observers. The system's goals are threefold: to aid human operators in understanding oceanographic processes, to enable human operators to play a role in adaptively responding to mission-specific data, and to accelerate mission planning from one vehicle dive to the next. The system uses standard lossy compression techniques to lower required data rates to those supported by commercially available acoustic modems (O(10) -O(100) bits per second).As part of the system, a method for compressing time-series science data based upon the Discrete Wavelet Transform (DWT) is explained, a number of low-bitrate image compression techniques are compared, and a novel user interface for reviewing transmitted telemetry is presented. Each component is motivated by science data from a variety of actual Autonomous Underwater Vehicle (AUV) missions performed in the last year.
