Technical requirements for shipborne integrated survey of land and sea topography

1 Scope

This document establishes the general principles for integrated shipborne land and sea topography surveys, and stipulates technical design, survey implementation, results production and quality Technical requirements for inspection, data compilation and archiving. This document is suitable for 1.500~1.2000 shipborne integrated survey of regional topography and landforms in the transition zone between sea and land, and other types of land and sea topography. The geomorphological survey project can be implemented as a reference.
