The new generation of Bathymetric Survey Systems is the SURVEYCASE. It is ideal for surveying in shallow water, harbors, and waterways and pre- and post-dredging applications. It is a simple-to-operate, complete hydro-graphic survey system contained in a single, portable, splashproof unit. The system includes an Intelligent Depth Sounder (IDS), an internal beacon receiver, and a WAAS receiver or an internal radio for use with SDI’s Remote Differential Base Station. This small, low-power, all-in-one package includes a daylight screen, waterproof keyboard and waterproof joystick.

SURVEYCASE digitizes the echo to 16-bit resolution and stores the full digital record on hard disk and provides playback with high resolution and detail. 65,536 shades of gray are digitized versus a maximum of 16 shades of gray typical of paper records. Depth resolution is maintained regardless of the depth range. Positions, events, and operator annotations are exchanged between HYPACK and SDIDEPTH programs. DEPTHPIC and SDIDEPTH software provide convenient replay and reprocessing of hydrographic data without hand digitizing or scaling of position. Navigation data and all other collection parameters are saved with all depth soundings. Post-processing with DEPTHPIC saves XYZ data in ASCII text format compatible with HYPACK, SURFER, AutoCAD, ArcView and GIS programs for contouring and TIN mapping.

SURVEYCASE operates from 12vdc and with navigation software, a battery and a boat, you are ready to survey. SDI’s proprietary display is daylight visible and also dims for excellent night viewing. SDI’s hardened computers include internal shock mounted electronics, armored display windows, marine grade aluminum display housings and non-corrosive impact resistant cases, and stainless hardware. Display controls and hinges are o-ring sealed and connectors are waterproof or splash resistant.
