RGB color orthophoto

The images are recordeed in Nadir and contain RGB (Visible Color Range) bands. The central parts of the images are selected for mosaicing. Photogrammetrically processed images are orthorectified and georectified. The planimetric accuracy is the same as the GSD. The mosaicing method ensures the best color matching between images and produces a gap-free mosaic.

CIR orthophoto

CIR orthophotos are recorded using infrared, red, and green (IR, R, G) bands, resulting false color images. The central sections of the images are selected for mosaicing. Photogrammetrically processed images are orthorectified and georectified. The planimetric accuracy is the same as the GSD. The mosaicing method ensures the best color matching between images and produces a gap-free mosaic.

RGBN orthophoto

The orthophoto consists of 4 channels: R, G, B, NIR. The central sections of the images are selected for mosaicing. Photogrammetrically processed images are orthorectified and georectified. The planimetric accuracy is the same as the GSD. The mosaicing method ensures the best color matching between images and produces a gap-free mosaic.

Open Street orthophoto

This product is intended to provide a complete overview of the street surface, suitable for displaying the entire surface of those streets, where the surface can be perfectly identified. The seamlines are hand-edited, whereby the buildings are depicted to their base, thus distorting the shape of the buildings ('folding them out'). Integrity of buildings are not considered in the generated product as the facades of the buildings are tilted.

Oblique RGB orthophoto /point cloud / mesh model

This product is based on oblique data acquisition. The survey is carried out using a camera system consisting of several RGB cameras intalled in 45°. "Dense matching" is used to extract point clouds from overlapping images. The point cloud can be used to create a 3D irregular triangle network (3D mesh). The 3D model can be textured with oblique images for realistic rendering.

Triangulated aerial images (for stereo evaluation)

This product consists of raw tiff images, external orientation after aerial triangulation, and a triangulation report.
