The Earth is constantly changing, and this makes it necessary for us to have an accurate, up-to-date understanding of our environment and resources. Be it monitoring weather and other environmental events or planning cities and managing resources, aerial photographs serve as a critical input to our ability to understand the Earth. These play an unmatched role in providing geospatially accurate visual representations of the Earth for mapping applications.
However, there exists a problem with aerial photographs. Due to the changing elevation of the terrain surface, the scale of ordinary aerial images vary across the image. To tackle this discrepancy, images need to be corrected. When an image is geometrically corrected, to create a uniform scale, it is said to be ‘orthorectified’. The resulting orthoimagery accurately represents the Earth’s surface. These images can be used to measure true distances. Orthophotos form the base for map making and give a true perspective on how buildings, trees, valleys and bends in a road truly appear in an area.

Excellent Orthophotos with Trimble OrthoMaster
When it comes to acquiring accurate data about an area, Cyient, a global leader in engineering, manufacturing, and digital transformation has been relying on orthophotos since decades. Trimble’s Inpho software has been helping it to precisely transform aerial images into consistent and accurate point clouds and surface models, orthophoto mosaics and digitized 3D features.
Cyient has been using the OrthoMaster Inpho module for their regular photogrammetric projects. They have executed multiple projects with scale varying from 1:500 to 1:2000 and with duration ranging from 1 month to 6 months.
Prior to using OrthoMaster, Cyient was spending a lot of manual effort on the projects. This got significantly reduced using OrthoMaster. OrthoMaster helps in improving productivity and delivering high-quality products to the customers. It ensures high speed batch processing and optimized hardware utilization for excellent productivity. It enables Cyient to create imagery with ensured constant scale. Cyient’s projects achieve high level of accuracy as OrthoMaster helps in effectively eliminating the relief displacements.
Cyient’s clients have been very satisfied with the deliverables, encouraging the company to stay associated with the Trimble products on an ongoing basis. Excellent service delivery adds to the pleasure of association, as Cyient’s spokesperson shares.
