Their view of the bottom is impeded by tens, hundreds, or thousands of feet of water, sometimes turbid. Occupying a position would require diving with scuba gear, a submersible, or a submarine. Besides, GPS signals don\u2019t travel underwater!<\/p>\n<p>Additionally, ships that can carry large sonar systems cannot navigate in very shallow waters, and small vessels that can navigate those waters cannot carry that large equipment. A recent bottom survey project in the waters off the coast of Scotland\u2019s western islands faced all of these challenges, plus an additional one: stitching together seven survey segments for each of 20 routes.<\/p>\n<p><a title=\"Mapping the Scottish Seabed\" href=\"https:\/\/www.xyht.com\/hydromarine\/mapping-the-scottish-seabed\/\" target=\"_blank\"><strong>Read more&#8230;<\/strong><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On land, surveyors face challenges due to rough terrain, human activity, weather, and more.
