Technologies
TerraSond's knowledge and ability to manage new technologies enables us to play a key role in the surveying and mapping industry.
We own and maintain a large suite of complex software and equipment that is necessary for executing accurate land and hydrographic surveying and mapping. The technology includes specialized tools for obtaining measurements and performing calculations on land and water that are essential for creating, editing and analyzing spatial and attribute data.
We support our staff's ability to manage new technologies by providing additional education and training. We also encourage hands-on experience to increase the conceptual understanding of geographic information systems (GIS) and their practical application for our projects.
Geographic Information Systems
GIS applications are time and resource saving tools that are used in every aspect of a hydrographic survey.
Remote sensing data is used for advanced field reconnaissance during the planning stages of a project, while electronic navigational charts are analyzed to predict the amount of time necessary to complete a project. Analysts use GIS to provide real-time updates of survey progress during survey operations, as well as identify, locate and attribute hazards to marine navigation.
TerraSond's most complex GIS tools are applied to the development of our final hydrographic products. Our modeling capabilities include three-dimensional fly through scenarios, high resolution digital terrain models, georeferenced video and time sequenced sea bottom analysis using sonar, lidar and seismic datasets. We also provide GIS-based data analysis that includes volume computations, pipeline condition and undersea cable route selection.
ArcGIS
ArcGIS is a system that allows for making accurate geographic information decisions. It facilitates collaboration and lets the user easily author data, maps, globes, and models on the desktop and serve them out for use on a desktop, in a browser, or in the field via mobile devices. 
Blue Marble Geographic Transformer
Blue Marble's Geographic Transformer converts raster image files from one projection/datum to another. It can create mosaics from multiple input files, or create output tiles, if desired. The tiling scheme can use either a row/column structure or the same 1.5-minute system that is used by U.S. Geological Survey to di… 
CARIS GIS Professional
CARIS GIS Professional software is an effective spatial analysis tool that permits the creation of digital paper charts to IHO standards as well as the management of information for coastal zone mapping and analysis. 
CARIS S57 Composer
CARIS S-57 Composer is desktop software used for the production of S-57 Electronic Navigational Charts (ENC), Additional Military Layers (AML) and Inland ENCs (IENC). 
dKart Image
The typical way of ENC production is the digitizing of the related paper chart. At the first stage a raster image for the paper chart (either black & white or color) is created. The next step is provided by dKart Image software. This step implies elimination of raster image distortions as well as geo-referencing of the… 
dKart Inspector
dKart Inspector is a powerful tool for ENC quality control. Since the first release in 1996, the program has won a wide international recognition among many Hydrographic Offices and S-57 data producers all over the globe. 
IVS 3D Fledermaus Professional
Fledermaus Professional is a powerful interactive 3D data visualization system that is used for a variety of applications including environmental impact assessment, mining, geology, and research. 
MakaiPlan Data Conversion
MakaiPlan is a Geographical Information System (GIS) to support fiber-optic cable laying. This sytem allows users to create submarine cable routes, define cables and in-line bodies, edit routes, define and adjust slack, instantly create a Route Position List (RPL) and Single Line Diagram (SLD). MakaiPlan can also est… 
MapInfo Professional
MapInfo Professional is the world's leading software for mapping and geographic analysis. MapInfo Professional enables users to perform detailed data analysis to drive insightful decisions leveraging the spatial component.
