◉ Service Content

Bathymetric survey	The determination of the height and plane position of the bottom point to the water surface is the central link of hydrographic survey and submarine topographic survey. The purpose is to determine the exact position of various navigation obstacles such as reefs and sunken ships, and to explore the shallowest water depth and its extension range.
Hydrological observation	In order to understand the distribution and variation of Marine hydrological elements, the observation and observation items are determined with the investigation tasks, generally including: water depth, water temperature, ocean current and other observations.
marine engineering survey	To carry out topographic and geomorphic survey and obstacle detection in the sea areas where Marine engineering is carried out.
sweeping survey	The purpose is to find out the navigation obstacles in the sea area, and to determine the depth of safe navigation of the ship refers to the measurement of the position of the shallowest and deepest underwater obstacles within the anchorage area of the port channel.
coastal topographic survey	The determination of the position and nature of the shoreline and the survey and survey of coastal land topography.
sea area ownership mapping	It includes the verification of territorial sea ownership, the definition of territorial sea boundary site, the measurement of sea register area, and the inspection and surveying of sea area for the completion of territorial sea chart.
