NDVI (Tilmaanta kala duwanaanshaha ee caadiga ah) ayaa ah tusmada sida caadiga ah loo isticmaalo ee loogu talagalay cabirka iyo la socodka caafimaadka dhirta iyo xoogga. Waxaa loo xisaabiyaa iyadoo la adeegsanayo sawirka dayax-gacmeedka, kaas oo cabiraya xaddiga iftiinka muuqata iyo meel u dhow ee ka muuqda daaqsinka. NDVI waxaa loo xisaabiyaa iyadoo la adeegsanayo algorithms gaar ah oo lagu dabaqay xogta laga helay sawirrada satalaytka. Algorithms-kaan waxay tixgeliyaan qaddarka iftiinka muuqata iyo soo dhow ee ka muuqda dhir, oo u adeegso macluumaadkan si loo abuuro tusmo loo isticmaali karo in lagu qiimeeyo caafimaadka dhirta iyo wax soo saarka. Si kastaba ha noqotee, shirkadaha qaarkood waxay iibiyaan kaamirooyinka NDVI ama dareemayaasha lagu dhejin karo diyaaradaha aan duuliyaha laheyn ama gawaarida kale ee hawada lagu hayo si ay u qabsadaan sawirrada heerka sare ah ee NDVI. Kaamirooyinkaasi waxay isticmaalaan miirayaasha takhasuska leh si ay u qabsadaan nalka la arki karo ee la arki karo iyo kuwa ka takhalusi kara, kuwaas oo ka dib looga baaraandegi karo iyadoo la adeegsanayo khariidado faahfaahsan oo ku saabsan caafimaadka dhirta iyo wax soo saarka.
Mudaharadii loo adeegsaday kaamirooyinka NDVI ama dareemayaasha ayaa sida caadiga ah la mid ah muraayadaha loo isticmaalay kuwa loo isticmaalo kamaradaha caadiga ah ama dareemayaasha. Si kastaba ha noqotee, waxay yeelan karaan astaamo gaar ah oo lagu wanaajinayo qabashada iftiinka muuqata iyo u dhow. Tusaale ahaan, kaamirooyinka NDVI qaarkood waxay u isticmaali karaan muraayadaha muraayadaha indhaha oo gaar ah si loo yareeyo xaddiga iftiinka muuqata ee gaaraya dareeraha, inta ay kordhineyso xaddiga iftiinka-ku-dhowaa. Tani waxay gacan ka geysan kartaa hagaajinta saxda ah ee xisaabinta NDVI. Intaa waxaa sii dheer, kaamarooyinka NDVI qaarkood waxay u isticmaali karaan muraayadaha muraayadaha indhaha oo gaar ah ama cabbir aperture si loo saadaaliyo qabashada iftiinka muuqaalka muuqaalka ah ee muuqaalka u dhow, oo muhiim u ah cabbiraadaha NDVI ee saxda ah. Guud ahaan, xulashada muraayadaha ndvi ee kamaradaha NDVI ama dareeraha ayaa ku xirnaan doona codsiyada gaarka ah iyo shuruudaha, sida xalka qaraarka ee la doonayo iyo baaxadda muuqaalka ah.
