LandsatLandsat eight is the newest satellite tv for pc in the Landsat program. The data high quality (sign-to-noise ratio) and radiometric quantization (12-bits) of the Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are higher than previous Landsat devices (eight-bit for TM and ETM+). Since it’s launch on February 11, 2013, Landsat 8 has been providing some truly gorgeous pictures of the earth’s floor. Beyond their beauty, these photographs are filled with information which may be manipulated to extract options and discern adjustments to the earth’s surface over time.

The Albers coordinates of the WELD pixels have a sub-pixel misalignment with the Albers coordinates defining the U.S. National Land Cowl Data dataset. The WELD Albers projection origin doesn’t fall completely at a WELD product pixel center. For example, the CONUS projection origin is in horizontal tile 17, vertical tile 22 at column 520.000, row 493.333, and the Alaska projection origin is in horizontal tile 5, vertical tile 16 at column 3390.000, row 2478.333 (the place column zero.5, row zero.5 refers to the center of the NW pixel of a tile). This difficulty might be rectified in the subsequent WELD product model.

LandsatMSS (Multi-Spectral Scanner), on LANDSAT-1 to five. Being one of the older era sensors, routine data acquisition for MSS was terminated in late 1992. The resolution of the MSS sensor was approximately 80 m with radiometric coverage in four spectral bands from the seen inexperienced to the close to-infrared (IR) wavelengths. Solely the MSS sensor on Landsat three had a fifth band in the thermal-IR.

Ikonos adalah satelit milik Area Imaging (USA) yang diluncurkan bulan September 1999 dan menyediakan information untuk tujuan komersial pada awal 2000. Ikonos adalah satelit dengan resolusi spasial tinggi yang merekam knowledge multispektral 4 kanal pada resolusi 4 m (citra berwarna) dan sebuah kanal pankromatik dengan resolusi 1 m (hitam-putih). Ini berarti Ikonos merupakan satelit komersial pertama yang dapat membuat image beresolusi tinggi.

For Sever, the ability of that picture modified the direction of his analysis. Originally a desert archeologist, after his first mission into the jungle he stayed to discover environmental impacts on ancient Maya societies, together with deforestation. Along with their archeological analysis, he and his research crew continued to make use of Landsat to monitor the tropical forests in the Petén.

Satelit ini memiliki bandwidth transmisi maksimum sebesar 85 Mbit/s dan ditempatkan pada ketinggian 705,3 km (438,three mil). Dibutuhkan sekitar sixteen hari untuk memindai seluruh bumi. Satelit ini adalah salinan identik dari Landsat 4 dan pada awalnya dimaksudkan sebagai backup Landsat 4 karena membawa instrumen yang sama, termasuk instrumen TM dan MSS. Instrumen MSS ini dimatikan pada tahun 1995. Dan pada akhirnya satelit ini berhenti beroperasi berakhir pada bulan Januari 2013.

For greater than forty years, Landsat satellites have offered a wealth of data that has informed our understanding of Earth options, phenomena, and environments as numerous as coral reefs, urbanization, tropical deforestation, and glaciers. Now, scientists at the Jet Propulsion Lab (JPL) at the California Institute of Technology have developed a strategy to substantially enhance photographs derived from Landsat techniques.

LandsatSatelit 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).
