A hybrid LiDAR-imaging device configured for aerial surveying of an overflown terrain comprising a, particularly nadir viewing, camera arrangement configured for acquiring camera data which are adapted for generating orthophoto data, wherein • an overall exposure area is provided by the camera arrangement, • the overall exposure area has a transverse extension defined as the extension along a direction which is foreseen to be the direction across a forward flying direction when the hybrid LiDAR-imaging device is installed to an aerial device, in the following called transverse direction, • the transverse extension is at least 60 mm, • the hybrid LiDAR-imaging device comprises a LiDAR arrangement for generating LiDAR data, the LiDAR arrangement comprising a first LiDAR device and a second LiDAR device, • the LiDAR arrangement is configured to have a LiDAR scanning field of view along the transverse direction which essentially covers an imaging field of view of the camera arrangement along the transverse direction, • the camera arrangement and the LiDAR arrangement are mounted into a common housing, the common housing being specifically foreseen to be installed to the aerial device, and • the hybrid LiDAR-imaging device is configured o to generate the camera data and the LiDAR data in one go, and o to generate, based on positioning information of a positioning system, positional reference information for as well the camera data as the LiDAR data, characterized in that • the first LiDAR device has a first longitudinal extension being defined as the extension axially along a ground viewing nominal first LiDAR axis and a first lateral extension being defined as an extension essentially orthogonal to the nominal first LiDAR axis, wherein the first longitudinal extension is larger than the first lateral extension, • the second LiDAR device has a second longitudinal extension being defined as the extension axially along a ground viewing nominal second LiDAR axis and a second lateral extension being defined as an extension essentially orthogonal to the nominal second LiDAR axis, wherein the second longitudinal extension is larger than the second lateral extension, • the LiDAR arrangement is configured that the first and the second LiDAR device are arranged relative to each other such that the first and the second nominal LiDAR axis are tilted with respect to each other, • the first LiDAR device has a first visual field cone and the second LiDAR device has a second visual field cone, and • the first and the second LiDAR device are configured that the first and the second visual field cone cross each other. • an overall exposure area is provided by the camera arrangement, • the overall exposure area has a transverse extension
