Ortofotófelvétel

Ortofotófelvétel is a Hungarian term that translates to "orthophoto capture" or "orthophotography." It refers to the process of creating an orthophoto, which is an aerial or satellite photograph geometrically corrected to remove distortion. Unlike a standard aerial photograph, an orthophoto has a uniform scale and is free from distortions caused by camera tilt, lens distortion, and terrain relief. This correction process is achieved through a technique called orthorectification, which uses a digital elevation model (DEM) of the area.

The result of ortofotófelvétel is an image that accurately represents the Earth's surface in a map-like quality. This means that measurements of distance, area, and shape can be taken directly from the orthophoto with high precision, similar to a traditional map. The process typically involves acquiring aerial or satellite imagery and then processing it with specialized software and geodetic control points.

Ortofotófelvétel has numerous applications across various fields. It is widely used in surveying, mapping, land management, urban planning, environmental monitoring, and agriculture. For example, it can be used to create detailed base maps, monitor land-use changes, assess crop health, or plan infrastructure projects. The accuracy and detail provided by orthophotos make them invaluable tools for decision-making and analysis of geographical data.
