Hyperspectral
DROACOR is suited for multispectral visible/near infrared sensors as well as hyperspectral instruments covering the 400–1000 nm spectral region or the 400–2500 nm spectrum.
Hyperspectral Methods
DROACOR® is a fully automatic atmospheric compensation and reflectance retrieval software
built from the ground for processing of imaging spectroscopy data sets.
It offers:
– Full spectrum automatic reflectance retrieval for image series
– Spectral recalibration for VNIR and SWIR using oxygen band positions
– Water vapor retrieval by spectral fitting technique
– Aerosol optical thickness estimate by enhanced dark object method,
– Adaptive atmospheric feature optimization
– Band interpolation or removal in fully absorbing regions
– Adaptive atmospheric transmittance treatment and spectral polishing.

For VNIR data, a sample of Specim AISA-FX is shown below:
About Us
ReSe Applications LLC provides Remote Sensing Software Applications for processing of multispectral and hyperspectral images. The provided software applications PARGE®, DROACOR®, ATCOR® and MODO are designed to process remote sensing data derived from devices like Hymap, APEX, AVIRIS, NEO’s Hyspex, Specim’s AISA, Headwall Photonics Hyperspec, Resonon Pika, Itres’ CASI, and more. It builds upon IDL technology to extend remote sensing software packages like ENVI.
