अंटार्कटिका का Landsat इमेज मोज़ेक (लीमा), Landsat 7 ETM+ से ली गई तस्वीरों को प्रोसेस करके बनाया गया है. यह एक आसान और बिना बादलों वाला मोज़ेक है.
यह LIMA डेटासेट, 16-बिट इंटरमीडिएट LIMA है.
यह मोज़ेक, पैन-शार्पन किए गए सामान्य सतह के रिफ़्लेक्टेंस
सीन (Landsat ETM+ बैंड 1, 2, 3, और 4) से बना है. इस मोज़ेक को बनाने के लिए, बिना बादलों वाली इमेज को सबसे ऊपर रखा गया था. साथ ही, टाइल में गड़बड़ी होने पर, इमेज की सीमाओं को काटा गया था.
ये इमेज, पब्लिक डोमेन में हैं. इनका इस्तेमाल बिना किसी शुल्क के और बिना किसी अनुमति के किया जा सकता है. हालांकि, अंटार्कटिका के Landsat इमेज मोज़ेक (LIMA) प्रोजेक्ट को क्रेडिट देने के लिए हम आपके आभारी हैं.

अंटार्कटिका का Landsat इमेज मोज़ेक (LIMA), Landsat 7 ETM+ से ली गई तस्वीरों को प्रोसेस करके बनाया गया है. इसमें बादलों की वजह से कोई रुकावट नहीं आती. यह LIMA डेटासेट, 16-बिट इंटरमीडिएट LIMA है. इस मोज़ेक में, पैन-शार्पन किए गए सामान्य सतह के रिफ़्लेक्टेंस सीन (Landsat ETM+ बैंड 1, 2, 3, और 4) शामिल हैं. मोज़ेक को …
