Site Viewer allows users to easily navigate around buildings and structures mapped with TIMMS (Trimble Indoor Mobile Mapping Solution). With seamless switching between 2D plan view and 3D fly-through modes, Site Viewer locates the structure precisely in a real-world coordinate system and provides precise latitude, longitude and elevation information for every point within the structure. Continuous 3D modeling is augmented with panoramic photographic imagery at regular intervals throughout the building, clearly identified by floor markers in both panoramic and 3D model modes. Features · View a building or structure in the context of its location · Seamlessly transition between 2D plan view and 3D first-person view · Control pan, zoom, elevation and navigation with on-screen sliders and joystick · Switch between 3D model and panoramic photo view when in first-person mode · Choose which layers to display for ease of viewing – switch on or off individual building floors and/or orthophoto views · Toggle views of walls, wall edges, annotations and markers, as well as floor markers for panoramic image locations · Measure distances from the imagery and view precise coordinates with built-in measurement and ray-trace tools For more information on the Trimble Indoor Mobile Mapping Solution see http://applanix.com/timms
