Specifications and Deliverables The Galveston District uses ONSITE software exclusively for single beam data acquisition. Specifications and deliverables for all surveys and related work products required as a result of this contract shall strictly adhere to the specifications listed below. Single-beam Data Pre and post surveys will be carried out using a single dual frequency survey echosounder. Data from the acquisition phase may be used to provide profile or bathymetric plots and volume estimations of channel sections. Raw single beam data The Galveston District requires use of the ONSITE survey acquisition and processing software and requires data gathered to be compatible with the processing methods that are standardized within the Galveston District. Single beam binary format data records are comprised of all available time tagged positions and depths for each station surveyed. The system must be capable of real time display of tide corrected data referenced to the channel design and the tides used will also be logged into the data records. While displaying the real time data it is also desirable to simultaneously view data from an earlier survey on the real time display. This will ensure that data gathered is compatible and comparable with existing data sets that are available within the District. Edited Single beam Data Processed single beam data will conform to the ONSITE ASCII text format. The data will be tide corrected and clean of anomalous soundings. Profiles may be plotted referenced to the channel design and will show the end areas for each template change of the channel. The data may also be plotted to a standard bathymetric chart individual soundings in plan view. The processed data files must be accessible to the Galveston District Survey Data System which reads and displays the data for use by other users within the District office. Shallow-Water Multibeam Data The AE's Multibeam data format shall provide complete traceability for all positions, soundings, and correctors including sensor offsets, biases, dynamic attitude, sound velocity, position, sensor position, date and time, vertical datum reducers, and sounding data from acquisition through post processing. Data quality and edit flags must be traceable. Raw Multibeam Data The AE must be able to submit full resolution Multibeam data in a format readable by CARIS HIPS (Version 5.3, by CARIS). Full resolution multibeam data shall be delivered fully corrected for tides, sound velocity, vessel offsets, draft and settlement and squat. These corrections may be made within CARIS, with data submitted as a complete CARIS project (including HDCS files, sound velocity files, Vessel Configuration, CARIS tide files, etc.). Or the data may be submitted fully corrected, such that it will be read in CARIS HIPS using a 'zeroed' Vessel Configuration file (.vcf) and a 'zero' tide file (.tid), etc. Full resolution data are defined as all data acquired and logged during normal survey operations. Information and specifications on CARIS HIPS and data formats may be obtained from CARIS at 506-458-8533. Edited Multibeam Data The AE will be required to submit an edited Multibeam data set in ASCII text format. Edited data are defined as fully corrected data that meet accuracy and resolution specifications are cleaned of all anomalous soundings, and serve as the source for all preliminary smooth sheet soundings and sun-illuminated DTM's. Edited data sets shall contain XYZ, z' (tide corrector), date/time stamp, and a unique identifier which indicates whether the sounding is depicted on the smooth sheet. Coordinates (XY) shall be state plane NAD 83, and depth (Z) shall be in feet to nearest 1 tenth of a foot (fully corrected for tide (MLT datum), sound velocity, dynamic and static draft, and all vessel offsets). Tide corrector (z') shall be in feet to the nearest tenth. Time shall be UTC to the nearest second. Data shall be binned, line-by-line, at a bin size not less than 5 feet + 5 percent of the depth, using shoal biased filtering. All depths shall retain their survey position and shall not represent the binned area centroid or other abstract position (i.e. binned, not girded data). Preliminary Smooth Sheet Data The AE will be required to submit the preliminary smooth sheet data set in ASCII text format. The smooth sheet data set shall contain XYZ. Coordinates (XY) shall be state plane NAD83, and Z shall be depth in feet to the nearest tenth of a foot (fully corrected for tide (MLT datum), sound velocity, dynamic and static draft, and all vessel offsets). Specific Multibeam Data The AE will be required to submit raw cross line data and data used for determining navigation time latency, pitch, roll, and yaw biases on separate media. Raw main scheme lines, which contain depths over dangers to navigation, wrecks, rocks or obstructions, shall also be included on separate media. The data format shall be such that CARIS HIPS can convert the data, thus making it compatible as described herein above. Side Scan Sonar Data The AE will be required to submit digital side scan data in a format readable by CARIS SIPS (version 5.3). Digital side scan sonar shall be geo- coded using the tow fish position. Information and specifications on CARIS SIPS and data formats may be obtained from CARIS. Side Scan Contact Images The AE will be required to submit digital images of all significant side scan contacts within the contact list. Digital images shall be in a standard image format (e.g., .tif, .gif, .jpg). The file name shall coincide with the contact name as depicted on the contact list. Side Scan Mosaics The AE will be required to submit a digital image file for each 100 percent coverage. The digital image file shall be in a standard geo-referenced image format. Tide and Sound Velocity Data The AE will be required to submit tide data and sound velocity data applied to all Multibeam depths on CD ROM or on the project data tapes. The hydrographer shall identify the data format and all data element descriptions (e.g., ASCII text file or Excel spreadsheet file; date/time referenced to UTC, tide relative to MLT datum to the nearest tenth of a foot. Vessel Configuration File The AE will be required to submit a CARIS compatible Vessel Configuration file (VCF) for each vessel used during survey operations. CARIS- compatible VCF shall contain those static and dynamic correctors and offsets, which are to be applied to the raw Multibeam data set submitted as referenced in Section 8.5.3. Information and specifications on the vessel configuration file format may be obtained from CARIS.
