p137r056_2x19781126-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p137r056_2x19781126。轨道号：137；行号：056；数据时间：1978-11-26。<br>陆地卫星（Landsat）是美国地球资源卫星系列。是美国用于探测地球资源与环境的系列地球观测卫星系统，曾称作地球资源技术卫星（ERTS）。<br>自1972年7月23日发射陆地卫星1号以来，到1984年3月1日已发射到陆地卫星5号。陆地卫星6发射失败。陆地卫星7（Landsat－7）于1999年4月15日发射升空，至今依然担负着重要任务。<br>在数据产品方面，Landsat－7与Landsat－5的最主要差别有：增加了分辨率为15米的全色波段（PAN波段）；波段6的数据分低增益和高增益数据，分辨率从120米提高到60米。

This dataset is an MSS dataset acquired by the Landsat 2 satellite, with the product identifier p137r056_2x19781126. The path number is 137, row number is 056, and the data acquisition date is 1978-11-26.<br>Landsat, previously designated as the Earth Resources Technology Satellite (ERTS), is a series of U.S. Earth resources satellites, representing a family of Earth observation satellite systems developed for detecting Earth's resources and environment.<br>Since the launch of Landsat 1 on July 23, 1972, up to March 1, 1984, the Landsat series had successfully deployed five satellites (Landsat 1 through Landsat 5). The launch of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and continues to perform critical Earth observation missions to date.<br>In terms of data products, the most prominent differences between Landsat 7 and Landsat 5 are: Landsat 7 added a 15-meter-resolution panchromatic (PAN) band; the Band 6 data was split into low-gain and high-gain datasets, with its spatial resolution improved from 120 meters to 60 meters.
