Orthophoto Processing - China

Orthophoto Processing

Feiyan Remote Sensing specialises in high-resolution orthophoto map processing including digital orthophotos and orthophoto mosaics from raw aerial survey photography and digital image capture.

Orthophotos combined with a topographic mapping project give a precise reference backdrop tool that enhances the users understanding of any project area.

Combined into orthophoto mosaics the imagery can cover large areas such as a catchment, river basin, highway or even local government area.

Process of Orthophoto Data Processing

Orthophoto data processing is the process of converting aerial photographs into a georeferenced and orthorectified image, which can be used in geographic information systems (GIS) or other mapping applications.

The steps involved in orthophoto data processing typically include the following: ● Image acquisition Aerial photographs are taken using a camera mounted on an airplane or drone.

● Image calibration The photographs are calibrated to account for camera distortion and other factors that may affect the accuracy of the resulting image.

● Image matching The photographs are matched to each other to create a seamless mosaic of the entire area being mapped.

● Digital elevation model (DEM) creation A DEM is created using LiDAR or other data sources to provide information on the elevation of the terrain.

● Orthorectification The aerial photographs are orthorectified using the DEM, which involves correcting for perspective distortion and other effects to produce a map-like image that can be used for accurate measurement and analysis.

● Color balancing The colors of the orthophoto are balanced to ensure accurate representation of the terrain and objects being mapped.

● Quality control The orthophoto is reviewed for accuracy and any errors or issues are corrected.
