 This trend in Earth observation allows for a high level of differentiation that’s a huge improvement over the normal optical images used in conventional satellites. Experts in earth observation have <a href="https://www.thehindu.com/sci-tech/science/isro-to-develop-full-fledged-earth-observation-satellite/article19458651.ece">called</a> the technology the ‘CATSCAN’ of Earth from space. The agency plans on using this technology to help with agriculture, soil quality, coastal zones, and inland waters among other geological environments. It’s all about the chip Hyperspectral imaging has been around for a while but each country has its own take on how to implement it. In <keyword id="3658" type="COUNTRY" weightage="20" keywordseo="India">India</keyword>’s case, the crux of hypex imaging lies in an optical imaging detector chip <a href="https://www.isro.gov.in/isro-develops-optical-imaging-detector-array-hyperspectral-imaging-applications">developed</a> by the Space Applications Centre (SAC) and manufactured by Semi Conductor Limited (SCL). The chip is capable of capturing images that can read upto 1,000 x 66 pixels.

(Chip on board. Photo source: ISRO) Hyperspectral imaging consists of much narrower bands as compared to multispectral imagery. Narrower measurement of wavelengths translates into more detailed imaging. Even in terms of scope, the former can identify 55 different spectral bands while the latter is only capable of capturing a maximum of 10 bands. India has already experimented with imaging spectroscopy when it launched the Chandrayaan-1, which had a hyperspectral camera on board to help map out the mineral resources available on the moon. The chairman of ISRO, K Sivan, told the <a href="https://timesofindia.indiatimes.com/india/isro-to-launch-hyperspectral-imaging-sat-with-30-foreign-satellites-on-nov-29/articleshow/66801810.cms">Times of India</a>, “We are going to launch HySIS at 9.59 am on November 29 from Sriharkota. Over 30 foreign satellites, including nano and mini satellites, will also be launch.” See also: <a href="https://www.businessinsider.in/india-successfully-launches-communication-satellite-gsat-29-using-its-heaviest-rocket/articleshow/66623518.cms">India successfully launches communication satellite GSAT-29 using its heaviest rocket</a> <a href="https://www.businessinsider.in/russia-to-help-india-with-its-first-manned-space-mission-may-train-astronauts-abroad-the-iss/articleshow/66086890.cms">Russia to help India with its first manned space mission, may train astronauts abroad the ISS</a> <a href="https://www.businessinsider.in/mars-orbiter-mission-completes-4-years-in-pictures/articleshow/65972664.cms">Mars Orbiter Mission completes 4 years: In pictures</a>
