- Seabed Surficial Mapping solutions combining SSS and multi beam bathymetry helps in geological assessment like sediment layers types of softness and hardness of the surveyed area. This helps in route survey for the planning of pipeline infrastructure, ensuring pipes/cables are not laid in hazardous areas
Use of such latest techniques helps deliver high quality, timely and cost effective solutions. IIC Technologies always strives to keep base with changing technologies to meet the demand of hydrographic community
IIC Technologies offers a full range of survey processing solutions and has successfully completed a wide variety of projects for both naval and national hydrographic offices. Our services include data post-processing, surface modeling, sounding selection and contour interpolation. For raw data, IIC Technologies use various software packages to apply biases, suppress beams, and select bin values, depth limits and resolution. The resulting Digital Terrain Model (DTM) is used to produce a specified surface, from which contours can be interpolated and soundings selected. To process dense data from echo sounder, side scan and LiDAR systems, IIC chooses powerful workflow tools including those published by CARIS, IVS, ESRI, Autodesk and Bentley.
- Surface Modelling & Sounding Selection
- Systems & Software
Processing raw datasets can be both complicated and time consuming. IIC Technologies experienced technicians use leading edge systems and proprietary routines to accurately and effectively process data captured during survey operations. IIC Technologies derives clean and fully validated results, ready for use with a variety of end products. Regardless of size or complexity, IIC Technologies can manage datasets from all types of sensors, including single beam, multi beam, side scan and LiDAR. Based on the platform, IIC Technologies incorporates vessel geometry and offsets, selects bin values, depth limits and resolution, grids the soundings, applies filters and biases, suppresses beams, and adjusts for sound velocity, tide and squat. Cleaning the soundings requires either a manual process (swath or 3D) or advanced automated filters based on Total Propagated Uncertainty (TPU) and Combined Uncertainty and Bathymetry Estimator (CUBE). To ensure the best quality standards, IIC Technologies performs vigorous QC throughout.
SURFACEMODELLING AND SOUNDING SELECTION
Once raw bathymetric data has been properly cleaned, validated and accepted, IIC utilizes the data for navigation surface modeling, contour interpolation and sounding selection. Creating a base surface requires the careful application of detailed parameters, including surface resolution and node computation algorithms. To interpolate contours, IIC must first generalize the high density soundings by creating a product level surface suitable for the specific end product. For final contour interpolation and sounding selection, a variety of constraints are considered, including product scale, printed vs. digital format, unique bottom characteristics and product purpose. The output from the processing routines is then interactively reviewed and the required cartographic adjustments made. For verification, IIC compares the new soundings and contours against the previously p ublished paper charts and ENCs. Satellite or aerial imagery, overlaid on the final DTMs, can also be used for verification.
SYSTEMS AND SOFTWARE
To effectively process raw datasets and the resulting Digital Terrain Models, IIC needs powerful tools provided a number of software suppliers. While IIC can work with virtually any software program, we typically use Fledermaus, CARIS HIPS/SIPS, Starfix.Proc, Starfix.Nav and Coda GeoSurvey for our raw data processing. For sounding selection, contour interpolati on and surface modeling, IIC uses CARIS BDB, Composer, AutoCAD Map, ArcGIS, ArcInfo, ArcView, and MicroStation. Other popular production line tools include Hypack, Kongsberg SIS, Surfer, etc. No matter what the system, IIC can process data and deliver products in virtually any format.
