Abstract |
Determining topographic features for the safety of waterways is one of the major, but not the only task for hydrographic surveys. As stated on the homepage of the International Hydrographic Organization (IHO, www.iho.org, visited on September, 19th 2009), Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their evolution, for the primary purpose of safety of navigation and all other marine purposes and activities, including economic development, security and defence, scientific research, and environmental protection.
The laboratory Hydrography at the HafenCity University Hamburg (HCU) tries to find future applications or applications that should be newly investigated for hydrographic platforms. For testing we use our equipment onboard our survey vessel Level-A. The following paper presents the HCU-Hydrographic Multi Sensor System (HCU-HMSS) and some applications in archaeology, gravimetry, and laserscaning. Additionally the precision of attitude senors and the use of precise point positioning without any reference stations will be taken into acount.
The precise point positioning shows accuracies in the dm level. Attitude sensors investigated did not fulfill the specified accuracy values. In archaeology high precision and resolution DTM or point clouds helps by finding the functions of underwater objects.
A short insight in not yet finished investigations with gravimeter and laserscanner measurements will be found in the report. |
