We regret any inconvenience. Even though multispectral data has been in use for decades and is the most widely used type of imagery to this day, new applications and algorithms are being developing continuously. Recently, some new multispectral sensors have radically changed in terms of spatial and spectral resolution.
Every project has it's own unique set of challenges.
By developing our own algorithms, we are free to move beyond what COTS packages are able to deliver. Even for many common image processing tasks included in COTS packages, EarthSat has proprietary algorithms to perform the task faster and better. Fusing high resolution panchromatic data with lower resolution multispectral data with COTS packages often leads to unrealistic colors, unsightly edges due to slight misregistrations, and is normally limited to three bands. EarthSat has developed a fusion algorithm that faithfully preserves colors, is forgiving of slight misregistrations, and operates on any number of bands simultaneously. EarthSat has developed proprietary spectral transforms over the last several decades that far out perform those available to the community at large.
