Topographic surveying refers to survey practices measuring and locating features on land for creating maps at different scales in hard copy and digital form. These maps and associated data have been widely used by the public and private sectors as one of the core basic information to make reference to for land administration, town planning, engineering development, education, transportation, election, emergency and other general uses, and is turning into one of the core components of spatial data infrastructure supporting smart city development.
