इस गैप-फ़िल्ड टैसल्ड कैप वेटनेस (टीसीडब्ल्यू) डेटासेट को, 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. ऐसा इसलिए किया गया, ताकि बादलों के छाए रहने जैसी वजहों से छूटे हुए डेटा को शामिल किया जा सके. 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.
