1 Scope

GB/T 12763.10-2007 is the Chinese national standard on specification for oceanographic survey - part 10: submarine topography and geomorphology, in the field of natural and applied sciences. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 13 August 2007 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2008. Classification: ICS 07.060, CCS A45. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section provides the basic requirements for seabed topography survey content, methodology, data compilation and investigation outcomes. This section applies to

1.100 million to

1.10 million scale seabed topography survey, larger scale seabed topography survey You can refer.

3 Terms and Definitions

3.1 Use transmitter and receiver refer to two orthogonal acoustic transducer array, obtain the vertical direction, bathymetric profiles by a large beam bathymetric dots, And formed by a series of bands sounding sounding profile formed in the direction of navigation, in order to achieve a method of high-resolution topographic measurements.

3.2 Using an acoustic transducer to scan the seabed, seabed echo signals obtained, to implement a method for Geophysical survey seabed topography imaging.

3.3 Uses sound waves transmitted and reflected on the seabed of the following medium, using acoustic echo principle, to obtain a sub-bottom structure of the acoustic profile Geophysical and survey methods.

4 General Provisions

4.1 Purpose and survey content According to the requirements of the task of the investigation, to obtain seabed topography data, survey data through the calibration and correction, data analysis, Processing and mapping, preparation of the survey area topographic map of the seabed and the seabed topography maps, reveal changes in seabed topography characteristics and laws of the survey area for economic Construction, national defense and scientific research to provide basic information on the seabed. Seabed topography survey operations include. technical design, equipment testing, measuring preparation, marine surveying, data processing and mapping, data Inspection and acceptance and archiving.
