SAL Engineering Maia WV Multispectral Camera
Features
The Maia WV is a UAV mounted multispectral camera with the same wavelength intervals as DigitalGlobe WorldView-2 satellite.
MAIA WV is based on an array of 9 sensors (1 RGB and 8 monochrome with relative band-pass filters) to detect multispectral imagery in the VIS-NIR spectrum from 390 nm to 950 nm.
