Topo Survey

Topography: A topographic map is a map illustrating the topography or shape of the land surface. Topographic maps show the locations and form of hills, valleys, streams, and other features as well as many man-made landmarks. topographic maps also show many other kinds of geographic features including roads, railroads, rivers, streams, lakes, boundaries, place or feature names, mountains, and much more. Older maps show additional features such as trails, buildings, towns, mountain elevations, and survey control points. Those will be added to more current maps over time.

DGPS: DGPS or Differential Global Positioning System is a system that is used to enhance and record the differences between the positions that are shown by GPS (Global Positioning System) signals and the real-time positions. DGPS provides real-time data. DGPS is used to identify the corrections in the positional readings from the GPS. It is also used to increase the accuracy in positioning during land surveys. This property of the DGPS makes it more accurate and expensive as it caters only to the local requirements. 

Orthomosaic: Orthomosaics are useful in the construction industry because they can provide continuous updates for ongoing projects, featuring the totality of the worksite, including the structure’s progress and the surrounding environmental impact. We can build 3D structures to insert into their map using cloud points, creating a virtual tour for key stakeholders in the project.

Orthomosaic mapping provides a highly-detailed, topographically-accurate view of the landscape below. 

 Construction firms also find orthomosaics particularly useful. They can get updated views of their construction sites on a regular basis, and they can leverage the accuracy of the orthomosaics for precise measurements. Software programs such as DroneDeploy, Pix4d like other allow users to measure distance, area, and volume. Construction firms can use these tools to calculate the volume of stockpiles, estimate material costs, and collect other valuable data without actually having to be at the construction site. Software programs can also use the raw data from the aerial photos to construct 3D models, which is another powerful tool for construction firms.
