Geospatial Engineers work within construction on the measurement and monitoring of projects as well as producing maps, plans and charts of different features. The main profession within civil engineering is engineering surveying (which is sometimes known as land surveying). Engineering surveyors are generally responsible for:

• Investigating land, using computer-based measuring instruments and geographical knowledge, to work out the best position to construct bridges, tunnels and roads
• Producing up-to-date plans which form the basis for the design of
  a project
• Setting out a site, so that a structure is built in the correct spot and to the correct size
• Monitoring the construction process to make sure that the structure remains in the right position and recording the final as-built position
• Providing control points by which the future movement of structures such as dams or bridges can be monitored

The term Geospatial Engineering includes the following specialist areas:

Engineering surveying:
preparation of maps and plans for the planning and design of structures as well as ensuring that the construction takes place to the dimensions and tolerances required.
Hydrographic surveying:
measuring and mapping the earth's surface that is covered by water.
Photogrammetry:
involves obtaining information from photographic images in order to produce a plan of an area.
Geographic Information Systems: involve collecting and manipulating geographic information and presenting the information in the form required.
Cartography / Visualisation:
accurately and precisely producing maps or plans and representing the information in two or three dimensions.
