PHOTOGRAMMETRY AND ORTHOPHOTOGRAPHY
Photogrammetry is the science of obtaining high-precision measurements from photographs and other forms of imagery.
Quick and cost-effective collection of data.
Highly accurate, reliable, quantifiable results.
Improved efficiency - one widely mapped area can be used for multiple analyses.
Provides an actual and permanent photographic record.
Easy to re-process data for new information without the need for expensive fieldwork to re-survey the area.
Ability to capture data in remote, unsafe or difficult to access locations, lowering safety risks
Data acquisition can be done without disrupting operations on the ground and analysis can be performed from the office rather than in the field.
Full colour models and point clouds are easy to visualise and analyse.
An Orthophoto is an accurate representation of the Earth' s surface. Orthophotos have the benefits of high detail, timely coverage combined with the benefits of a map including uniform scale and true geometry. Photomapping can provide the following scanned and geo-referenced products: Digital Ortho-photography.
An orthophoto is an aerial image that has been geometrically ortho-rectified so that the image is uniform from edge to edge
Orthophotos are corrected to remove terrain effects and distortions produced by camera sensors.
Orthophotographs are commonly used in GIS as base maps on which other layers of data are superimposed.
A digital terrain model is added as a means of collecting ground points to indicate the elevation changes. When control points are identified on the aerial photos, stereo models are developed and geometric distortions are estimated. The image is rectified and georeferenced using mathematical models of Photogrammetry to remove tilt, terrain, atmospheric and other digital image distortions.
