I don't know if you have found out that when searching for the word "measurement" on the Internet, there is one item in the relevant recommendation: the difference between measurement and engineering measurement, which is definitely a question of many people. I don't know how you understand the similarities and differences between the words "measurement" and "mapping". Today, Bian Xiao from Tendering Network will explain to you what survey and measurement are and what is the difference between them.

survey

Investigation refers to sampling and testing geological conditions before engineering design, and providing geological exploration reports for design use.

Survey and drawing

Surveying and mapping is based on the standard topographic or geological map, observing, measuring and describing various geological elements directly or indirectly related to the project in the survey site and its periphery, which provides a basis for comprehensively drawing the engineering geological map, preliminarily judging the engineering geological environment of the survey site, and reasonably arranging the exploration and test work.

The difference between surveying and mapping

Exploration is a deep investigation of the surface and geology, such as prospecting. Surveying and mapping is only the surface measurement of geographical environment and drawing charts. These are two different projects. Surveying and mapping projects need to sign surveying and mapping contracts. It should not be a survey contract.
