Abstract

Whether using an airborne lidar or a ship-based acoustic system, all hydrographers must contend with geometric system calibrations. A poorly aligned system leads to erroneously reported depths, diminished system resolution and internally inconsistent datasets. Most of today’s calibration procedures are cumbersome and subjective enterprises that possess little statistical merit. This paper presents a least squares adjustment algorithm designed to calibrate a (presently under-development) lidar. This method is automated, objective, repeatable, and reports a confidence on the calibration values. Using simulated lidar datasets, the algorithm is explained and demonstrated. A brief modification is also proposed to expand the use to multibeam echosounders.

Authors should also bear the following points in mind:

  1. The title should be concise and reflect the subject matter
  2. Long passages of text should be avoided by the appropriate use of sub-titles
  3. References, which should include only publications cited, should be referenced in the text, thus (Smith, 1988), and be listed alphabetically in the Reference section conforming to the Harvard style. Some typical examples follow:

Please note that articles will be returned to Authors who do not conform to the IHR referencing policy.

Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form. In such cases referred material can be cited using numbered superscripts in the text and the list of references thus replaced by a section headed 'Notes' in which explanation of the superscripts is given. Material which has been consulted but not specifically referred to in the text can be included in a separate 'Bibliography'.

Please note that references will not be checked by the Editor and the responsibility for the accuracy rests solely with the author(s).
