Scientific Data (SD) Types

Introduction

One of the primary features of Fledermaus is its ability to load a variety of data types at different resolutions and explore and analyze them together in a 3D scene. Each object type supported by Fledermaus is called a scientific data class or SD class for short. Any file that is prepared for loading into Fledermaus is given the filename extension .SD, as in "mysurface.sd".

Each SD class contains a user interface component, which is displayed in the Data Object Control Region of Fledermaus or DMagic. Interaction with the objects is normally performed through this graphical interface; however, controls for general exploration in the Main Visualization Window remain basically the same for any object.

This section describes each SD class supported by Fledermaus and provides details on:

• what data it represents,
• how its data is displayed in the 3D virtual world,
• the graphical user interface used to interact with the object, and
• some notes on how data in the class is prepared for the visualization process.

A summary of the SD classes described in this section are as follows:

• Root Node
• Digital Terrain Model (DTM) Classes- SonarDTM, Surface Series
• 3D Geometric Classes – points, lines, polygons, grids, and solid models.
• Imagery Visualization Classes– geo-image, vertical image, and imagery curtain.
• Simple Visualization Classes – grid, plane, cube, label, and quadratic.
• PFM Class - Geo-Spatial quality control 
• CUBE Tools
• Vessel Class– real-time Vessel or ROV monitoring.
• Water Column Visualization Classes
• Common Object Controls
• Pipeline Visualization Classes
• Dynamic Surface Class
