As long as you have the intermediate certificate of engineering investigation, you can engage in engineering investigation in China. The methods and skills needed for engineering survey are the operation of level and total station. Typing is too much trouble. Ask someone else.
Hehe ~! Engineering survey is the use of total station for construction lofting. Studying engineering survey and doing this work need systematic study. I studied in college for three years and practiced for five months, but I can still finish the survey of municipal engineering independently. As for the person above who said that the Provincial Bureau of Surveying and Mapping has training, I don't know. If you want to do this job, I'm afraid I don't know that you can take short-term training courses. I have to find this master to take you for a while.
You can set up a set of engineering survey teaching materials to read, and give you this website, which contains the instructions for the use of the total station, but if you want to read or download it, you need its points, which is quite good.
