When it comes to providing high resolution Ortho-photography, Landmark Survey shines through. A combination of the state-of-the art Ortho-photographic technologies, software and hardware packages, plus the best-in-class Ortho-photographic processes ensures that the quality, resolution, and accuracy of the Ortho-photos are of the highest standard. Talk about picture perfect, and you won't be wrong.
An overview of the processes carried out by our team of experienced and qualified experts is broadly divided into the following five processes.
The first step in obtaining the desired results lies with the aerial photograph. Using man or unmanned aerial vehicles, an aerial photograph of the affected area is taken during optimal conditions using an advanced aerial camera equipped with Forward Motion Compensation. The result is a clear, sharp, high resolution image.
Here horizontal and vertical terrestrial control is used to adjust the aerial photograph to determined ground coordinates and features. Our team of experts might sometimes use airborne GPS coordinates and analytic triangulation for the best result.
The goal is to produce a raster image of the aerial photograph which will be used in the subsequent phase.
The aerial photograph is used to produce a model that represents the accurate elevation of the terrain.
To produce an accurate image, the raster image of the aerial photograph is corrected using the DEM.
By insisting on the best industry backed image processing software, high resolution aerial cameras, best photographic techniques, latest scanners, high-tech workstation, and superb output devices with proven competence, at Landmark Surveys, we've been able to meet the demands of even the most complex requirements and exceed the expectations of 1000+ clients.
