What is the significance of indoor and outdoor work in surveying and mapping industry?

Surveying field work: field investigation and measurement, data collection.

Surveying indoor work: the data collected by field investigation and measurement are compiled into indoor work data.

Construction survey is the survey work of construction control, lofting and completion acceptance. Contrary to the general surveying and mapping work, construction lofting is to mark the position, shape, size and elevation of the designed building on the ground according to the design drawings, so as to carry out construction according to these marked points and lines.
