Drone Aerial Mapping & Land Surveying

Orthophotos are also referred to as orthomosaics, orthoimages and orthophotographs. With orthorectification, which adjusts for topographic relief, lens distortion and camera tilt, orthophotos can be used to accurately measure distance. This makes orthophotos incredibly useful in allowing surveyors to work without entering the field.

Orthomosaics typically cover large areas and are created by stitching thousands or tens of thousands of images together. Image capture and processing is therefore extremely important and should be managed by experienced professionals.

Construction and urban planning projects benefit from orthomosaics, which enable high-resolution zoom and provide an enduring and defensible record of progress.

Urban planners can easily collect large volumes of real-time data with which to evaluate requirements and model the impact of potential changes. Orthomosaics can also form the basis of digital twins, which are increasingly utilised for smart city developments.

The enduring nature of high-resolution orthomosaics provide farmers insight to crop conditions, land changes over time and to plan new fields.

Topographic surveys similarly assist land planning, allotments, road construction and preparation for utilities and more. Detailed site topography also assists pre-development engineering assessments, with the outputs available for import to BIM and CAD systems. Drone data collection is incredibly economical in comparison to traditional methods and enables a new level of time-lapse site management.

Orthomosaics provide detailed and even interactive maps of commercial property and real estate, and are particularly useful for larger properties. Platforms such as Geotech Mapping retain an enduring record of the properties and facilitate review of property and structure changes over time.
