applications in the field of Civil Engineering?

Answer 1

geotagging

•Process of assigning a geographical reference, i.e, geographical coordinates (latitude and longitude) + elevation - to an object.

• This could be done by taking photos, nodes and tracks with recorded GPS coordinates.

• This allows geo-tagged object or SP data to be easily and accurately located on a map.

use in civil engineering

•Mapping and visualization of an irrigation system; showing the main canal and the sub-laterals, current service area, service area to be generated as a result of irrigation improvement + geotagged photos of the inventory of condition of the structures and the canals , eqmt mobilization, progress photo graphs

•Visualization of a Community Learning Center in a conflict affected area: showing specific location, polygon of the lot , and ground photos (with coordinates, date and time taken)
