The scope of academic research as an application area is huge, even when limited to disciplines using Fledermaus as an integral part of their processing, analysis, and data presentation. Fledermaus has been used in ocean mapping research since its development in the mid-1990s, as a 3D geographic information system and as the premier 3D visualization tool for dense multibeam sonar data. Since that time, Fledermaus has been embraced by researchers in many fields. The ability to quickly process data usingCUBEThe CUBE algorithm was developed by Dr. Brian Calder at the Center for Coastal and Ocean Mapping/Joint Hydrographic Center at the University of New Hampshireand Area Based processing methods to generate the best possible seabed surface is key for anyone using dense multibeam, interferometric, or lidar data as the basis for further research and interpretation, including geologists, sedimentologists, and biologists. For those collecting multibeam backscatter, the advanced backscatter processing techniques, 64-bit software, multi-threaded processing, and plug-in architecture provide for quick, flexible mosaic creation and signal-based Angle Range Analysis(ARA)The FMGeocoder Toolbox (FMGT) product and ARA analysis originates from research by Dr. Luciano Fonseca at the Center for Coastal and Ocean Mapping/Joint Hydrographic Center at the University of New Hampshireseafloor characterization, creating a picture of the seabed make-up. Importing data in other formats and from other applications, including imagery, ASCII, GMT GRD, NetCDF, Esri ArcMap grids and shapefiles, ETOPO, Surfer, and Floating Point GeoTIFF, and USGS DEMs, is wizard based, making it easy to move supporting data into your scene. New interpretation tools for creation of geologic, sediment, or habitat maps allow you to digitize boundaries in 3D, using all of the available data to support your decisions.
The integration of time in the Fledermaus software - the fourth dimension - allows for easy import and animation of time-attributed data such as earthquakes and mammal position; scientists using ROVs and AUVS for exploration or monitoring the location of anything receiving a NMEA location string can see the position in real-time within their visualization. For those interested in the water column – acousticians, fisheries biologists, marine geologists – Fledermaus provides the most intuitive, user-friendly water column processing package available for detecting and visualizing features such as gas plumes and fish schools. Many in academia are usingEsri ArcGIS®ArcGIS® trademark provided under license from Esri, FM Viz4D, or Any Fledermaus Bundlesoftware for its powerful GIS queries, extensive algorithms, geodatabase storage, and plug-in capability; Fledermaus provides a direct link to ArcGIS to facilitate two-way transfer of data between the software packages. Finally, one of the most important parts of research is presenting your results. 4D Fledermaus scenes can be distributed and viewed using the free downloadable viewer, iView4D. Using a mouse or 3D interaction device, you can create impressive fly-throughs to distribute as WMV or MPEG movie files; you can also export your data to KMZ for viewing in Google Earth. Fledermaus also provides image creation tools, allowing you to generate high-resolution perspective images, profile images, and sun-illuminated georeferenced images for posters, presentations, and publication.
