Multibeam Processing Services
At Tekmap, we offer a full range of multibeam processing services. This includes working with the raw survey data, through map production, to custom map products and 3D visualization.
There are two basic stages in processing multibeam data. The first step involves cleaning and manipulating the data in preparation for import into a GIS. The second step involves the projection of data into geographic space and the import into a GIS. Our data cleaning and data manipulation services include:
- Navigation cleaning and editing.
- Backscatter beam angle corrections.
- Tidal and altitude corrections.
- Attitude (roll, pitch, and heave) corrections.
- Automatic filtering and manual editing.
- Custom corrections to rescue problem data.
Final Products
After importing the multibeam data into a GIS, a number of products are available. For examples of output products, please visit the Gallery.
| Product | Description |
|---|---|
| High resolution maps | Provide gridded bathymetric, backscatter, and sidescan (seabed) maps. |
| Vector data | Provide navigation as a vector file with survey associated metadata. |
| Data fusion | Combine two or more data sets (for example draping sidescan over bathymetry). |
| Bathymetric cross-sections | Available on a single straight line or along a user defined path (for example mapping a pipeline route). |
| Sun illuminated bathymetry | Produce a conventional grey scale map by illuminating bathymetry from a user defined sun azimuth, altitude, and vertical exaggeration. |
| Custom color tables | Use standard and custom color tables designed to enhance specific features or targets. |
| 3-D visualization | Provide custom 3-D views, overlays with optional cutting planes. |
| 3-D Fly Through's | Provide high resolution fly-through animations from processed data. |
| Statistical analysis | Do simple statistic extraction from data such as histograms, to more complex spatial analysis. |
| Multiple GIS Support | Provide output GIS products in a wide variety of raster and vector formats. |
| Final map production | Provide digital and hard-copy output of processed data. |
