p048r027_2x19790718-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p048r027_2x19790718。轨道号：048；行号：027；数据时间：1979-07-18。<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 is an MSS dataset from the Landsat 2 satellite, with the scene identifier p048r027_2x19790718. Its path number is 048, row number is 027, and data acquisition date is 1979-07-18.
Landsat, the U.S. Earth Resources Satellite series, is a series of Earth observation satellite systems developed by the United States for detecting Earth's resources and environment. It was formerly designated as the Earth Resources Technology Satellite (ERTS).
Since the launch of Landsat 1 on July 23, 1972, through to March 1, 1984, a total of five Landsat satellites had been launched (Landsat 1 to Landsat 5). The launch of Landsat 6 ended in failure. Landsat 7 (Landsat-7) was launched on April 15, 1999, and continues to perform critical Earth observation missions to date.
In terms of data products, the most prominent differences between Landsat-7 and Landsat-5 are: The addition of a 15-meter-resolution panchromatic band (PAN band); the data of Band 6 is provided in two gain modes (low-gain and high-gain), with its spatial resolution increased from 120 meters to 60 meters.
