यह गैप-फ़िल किया गया टैसल्ड कैप ब्राइटनेस (टीसीबी) डेटासेट, Lobser और Cohen (2007) में बताए गए टैसल्ड-कैप समीकरणों को MODIS BRDF-corrected imagery (MCD43B4) पर लागू करके बनाया गया था. इसके बाद, डेटा में मौजूद खाली जगहों को भरने के लिए, Weiss et al. (2014) में बताए गए तरीके का इस्तेमाल किया गया. इससे, बादलों के छाने जैसी वजहों से मौजूद न होने वाले डेटा को हटाया जा सका. डेटा में मौजूद अंतर को भरने के बाद, मान्य वैल्यू पक्का करने के लिए डेटा को [-1, 2] की थ्रेशोल्ड वैल्यू के हिसाब से काटा गया.
इसके बाद, हर आठ दिन में ~1 कि॰मी॰ के रिज़ॉल्यूशन पर तैयार किए गए डेटा को समय के हिसाब से इकट्ठा किया जाता है, ताकि महीने और साल के हिसाब से प्रॉडक्ट तैयार किए जा सकें.

यह गैप-फ़िल किया गया टैसल्ड कैप ब्राइटनेस (टीसीबी) डेटासेट, MODIS BRDF-corrected imagery (MCD43B4) पर Lobser और Cohen (2007) में बताई गई टैसल्ड-कैप इक्वेशंस को लागू करके बनाया गया था. इसके बाद, Weiss et al. (2014) में बताए गए तरीके का इस्तेमाल करके, डेटा में मौजूद अंतर को भरा गया. ऐसा इसलिए किया गया, ताकि बादल छाने जैसी वजहों से छूटे हुए डेटा को शामिल किया जा सके. …
