摘要：
Electronic devices can be used to make both the horizontal measurements (in air) and the vertical (through water). To improve stability of the boat in which the surveying crew operates, multi-hull boats and air-cushion craft are being used or considered. Types of horizontal positioning hardware - including microwave and radar - are described, as are types of water depth measuring gear (among them acoustical, aerial photography, satellite imagery, side-scan sonar, and sub-bottom profiling).
