Digital orthophotos are aerial photographs, which are rectified for tilt, relief and other systematic errors from perspective projection. A digital orthophoto represents ground features in their "true map positions" via a raster image.

Increasing demand and popularity

Rapid improvement and availability of hardware for raster graphics visualisation and growing importance of complex systems (GIS/LIS) have created an increased demand for digital orthophotos. Digital orthophotos have expanded their popularity to include applications in transport planning, land use planning, natural resource planning, hydrology planning and inventorying of infrastructure and natural resources.

Save cost and time

Digital orthophotos serve as innovative base maps, offering a complete and accurate foundation for a GIS. This can be an inexpensive substitution for and / or addition to regular line maps. The digital orthophotos can be produced in less time and at lower costs.

Orthophotos produced by COWI India are meticulously colour-balanced and edge-matched, giving a uniform and consistent impression across the mosaic. This also applies to orthophotos covering thousands of square kilometres.

We currently use Inpho Orthobox and SocetSet mosaic for rectification of orthophotos. We offer allocation of dedicated and trained production teams for project execution in order to ensure uniformity and quality control as per project size and duration.
