  2. Post-Processing A Brief Introduction

  3. Technically, post-acquisition processing GeoDAS can process in real-time but: Post-processing allow more flexibility and power in detecting and dealing with data noise and image artifacts. Post-processing tools allow you to review all your data, for creation of better mission products What is “Post-processing”?

  4. Clean up noise in the data Remove data artifacts Make mission products, Maps DEM’s Target locations Why Do Post-processing?

  5. Typical sidescan artifacts Beam Pattern Artifacts Bottom-tracking Errors Gain Changes

  6. Typical Bathymetry Artifacts Depth outliers (noisy data)

  7. Typical navigation and heading Noisy navigation and heading data

  8. GeoDAS-Desktop. Economic solution for data replay, navigation editing and production of simple mosaics. OICToolkit. UNIX-based full-featured post-processing package. OICcleansweep. New, PC-based post-processing package for sidescan and bathymetry. OIC Options for Post-processing

  9. Introducing OICcleansweep:Post-processing for Windows

  10. Retains many of the features of OICToolkit “swath-based” processing “point & click” selection of data Interactive editing of gains & bottom-tracking Adds new, more powerful features Better data and swath bookkeeping Navigation “wizard” to aid in sensor re-nav “Quality” based filtering for bathymetry More powerful mosaicking tool allows interactive blending of multiple swaths Target-marking tool allows clipping of full-resolution GeoTIFFs from sidescan, and pasting them on mosaics OICcleansweep

  11. Superimposition of EOID GeoTIFFTarget Snippets on Sidescan Mosaic
