Utilizing photogrammetry services has become the preferred method for geospatial mapping solutions (the accurate representation of geographic locations and characteristics of terrain in real space), especially in those areas that are highly forested, extremely congested or in rugged landscapes that offer limited access to surveyors. This type of detailed information is critical as unused land development is the next frontier for commercial, industrial and residential applications.
The field of photogrammetry combines aerial satellite photography with digital techniques to compose 2D and 3D real life rendering of surface terrain. The resulting output from photogrammetry services can be a 3D model, 2D drawing or a map. Partner with a service that uses highly skilled staff experienced in completing challenging tasks and only use data from accurate sources based on reliable information.
Accurate data is collected from satellite images, aerial photographs and terrain maps. Each feature is then given a unique line weight, line style and color to represent terrain contours, profiles and elevations of features such as vegetation, water bodies or building footprints.
Real world measurements are digitally derived with the use of specialized computer software that will convert the patterns of a mass of 3d point cloud into a representation of the ground surface. The science relies on the fundamental use of the theory of ‘triangulation’, which takes the mathematical intersections of multiple photographs of the same area to produce three dimensional coordinates of land features.
Photogrammetry output is then translated into maps that have a high quality of detailed illustration of land features. For 2D applications, contour drawings are still used extensively by civil engineers to plot topography; with photogrammetry, this laborious process is eliminated and can be produced automatically. Combining photogrammetry output with GIS information, means light poles, drains, fire hydrants and utility mains can all be superimposed on one model.
