Digital Orthophotos Lower Saxony (DOP20)
Description
Digital orthophotos (DOP) are high-resolution, distortion-free images of the Earth's surface. Since 2001, they have been produced by a computer-aided equalisation process with a geometrical accuracy of approximately +/- 0.4 m from aerial images, usually on a scale of 1: 12 000 are available as vertical images. The pixel size of the DOP on the ground is 0.4 m x 0.4 m as standard, and since 2007 only 0.2 m x 0.2 m. They are coloured, razor-sharp and as precise as a map. Digital orthophotos are true to scale and can thus be directly compared with maps of the same scale or digitally combined with specialist data, for example road planning.
Since 2008, an infrared channel has also been included in the creation of digital orthophotos and is offered in various forms:
Characteristic RGBI: representation together with the three color channels of the normal orthophoto;
Characteristics of CIR: display of the infrared channel together with the red and green channel of the normal DOP;
Type of IR: Representation of the infrared channel only
