Satelit Landsat merupakan salah satu satelit sumber daya bumi yang dikembangkan oleh NASA dan Departemen Dalam Negeri Amerika Serikat. Satelit ini terbagi dalam dua generasi yakni generasi pertama dan generasi kedua. Generasi pertama adalah satelit Landsat 1 sampai Landsat 3, generasi ini merupakan satelit percobaan (eksperimental) sedangkan satelit generasi kedua (Landsat four dan Landsat 5) merupakan satelit operasional (Lindgren, 1985), sedangkan Short (1982) menamakan sebagai satelit penelitian dan pengembangan (Sutanto, 1994). Satelit generasi pertama memiliki dua jenis sensor, yaitu penyiam multi spektral (MSS) dengan empat saluran dan tiga kamera RBV (Return Beam Vidicon).
Now, the US effort is to be bolstered by the brand new European observer, which has been calibrated in such a manner that its footage will be a wonderful match with the American ones. Generasi kedua, yaitu Landsat 4 dan Landsat 5, merupakan satelit operasional (Lindgren, 1985),sedangkan Quick (1982) menamakan sebagai satelit penelitian dan pengembangan (Sutanto,1994). Week01 = January 1st to January seventh, Week53 = December thirtieth to December thirty first (leap years) or December 31st (non-leap years).
The Thermal Infrared Sensor also uses the push broom technique and high-tech units known as quantum properly infrared photodetectors to precisely measure how the planet absorbs and displays warmth. Each Landsat, for example, passes over the same portion of the earth on the equator as soon as each sixteen days, whereas a system of adjustable mirrors permits SPOT’s sensors to watch a site 7 days out of 26.
Video: The Columbia Glacier in Alaska is one among many vanishing world wide. Glacier retreat is one of the most direct and understandable results of climate change (NASA’s Earth Observatory). Jensen (1986) mengemumakan bahwa kebanyakan saluran TM dipilih setelah analisis nilai lebihnya dalam pemisahan vegetasi, pengukuran kelembaban tumbuhan dan tanah, pembedaan awan dan salju, dan identifikasi perubahan hidrothermal pada tipe-tipe batuan tertentu. Knowledge processing beyond the Degree 1 products distributed by way of EDC is the responsibility of the users and shall be achieved with user-owned capabilities or these out there from personal sector suppliers.
Eric Mack has been protecting expertise and the world because the late nineteen nineties. As well as being a Gizmag regular, he at present contributes to CNET, NPR and different shops. It is useful (and needed) to evaluate the accuracy of land cover classification, with a purpose to perceive the reliability thereof, and to establish map errors. The satellite tv for pc’s photo voltaic panel unfolded as deliberate a few minutes after separation, however it would take three months to activate, calibrate and check out the satellite tv for pc’s two science instruments and spacecraft subsystems. When the spacecraft begins routine operations it is going to be often called Landsat eight.
