NDVI (Tusmada Kala Duwanaanshaha Dhirta ee Caadiga ah) waa tusaha caadi ahaan loo isticmaalo cabbiraadda iyo la socodka caafimaadka iyo xoogga dhirta. Waxaa lagu xisaabiyaa iyadoo la isticmaalayo sawirka dayax-gacmeedka, kaas oo cabbiraya cadadka iftiinka muuqda iyo kuwa u dhow ee ka muuqda dhirta. NDVI waxaa lagu xisaabiyaa iyadoo la isticmaalayo algorithms gaar ah oo lagu dabaqay xogta laga helay sawirada dayax-gacmeedka. Algorithms-yadani waxay xisaabta ku darayaan cadadka iftiinka muuqda iyo kuwa dhow-infrared ee ka muuqda dhirtu, waxayna isticmaalaan macluumaadkan si ay u soo saaraan tusmaynta loo isticmaali karo si loo qiimeeyo caafimaadka dhirta iyo wax soo saarka. Si kastaba ha ahaatee, shirkadaha qaarkood waxay iibiyaan kamaradaha NDVI ama dareemayaasha lagu dhejin karo diyaaradaha aan duuliyaha lahayn ama kuwa kale ee hawada si ay u qabtaan sawirada NDVI ee heer sare ah. Kamaradahani waxay isticmaalaan filtarrada khaaska ah si ay u qabtaan iftiinka muuqda iyo kuwa u dhow labadaba, kaas oo markaa lagu farsamayn karo iyada oo la adeegsanayo algorithms NDVI si loo soo saaro khariidado faahfaahsan oo caafimaadka iyo wax soo saarka dhirta.
Muraayadaha loo isticmaalo kamaradaha NDVI ama dareemayaasha ayaa caadi ahaan la mid ah muraayadaha loo isticmaalo kamaradaha caadiga ah ama dareemayaasha. Si kastaba ha noqotee, waxaa laga yaabaa inay leeyihiin astaamo gaar ah si ay u wanaajiyaan qabashada iftiinka muuqda iyo kuwa u dhow ee infrared. Tusaale ahaan, qaar ka mid ah kamaradaha NDVI ayaa laga yaabaa inay isticmaalaan muraayado leh dahaar gaar ah si ay u yareeyaan cadadka iftiinka muuqda ee gaara dareenka, iyadoo la kordhinayo qadarka iftiinka infrared-ka dhow. Tani waxay gacan ka geysan kartaa hagaajinta saxnaanta xisaabinta NDVI. Intaa waxaa dheer, qaar ka mid ah kamaradaha NDVI ayaa laga yaabaa inay isticmaalaan muraayadaha leh dhererka fog ee gaarka ah ama cabbirka daloolka si ay u wanaajiyaan qabashada iftiinka ee spectrum infrared-ka dhow, taas oo muhiim u ah cabbirada NDVI saxda ah. Guud ahaan, doorashada muraayada kamarada NDVI ama dareeraha waxay ku xirnaan doontaa codsiga gaarka ah iyo shuruudaha, sida xallinta meelaha la rabo iyo baaxadda muuqaalka.
