p170r071_1x19721109-陆地卫星遥感影像

本数据集为MSS，Landsat1卫星的数据集，p170r071_1x19721109。轨道号：170；行号：071；数据时间：1972-11-09。<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 MSS data from the Landsat 1 satellite, with the product identifier p170r071_1x19721109. Its path number is 170, row number is 071, and the data acquisition date is 1972-11-09.
The Landsat program is a series of American Earth resources satellites. It is a series of Earth observation satellite systems developed by the United States for detecting Earth's resources and environment, and was formerly referred to as the Earth Resources Technology Satellite (ERTS).
Since the launch of Landsat 1 on July 23, 1972, up to March 1, 1984, Landsat 5 had been successfully launched. The launch of Landsat 6 failed. Landsat 7 was launched on April 15, 1999, and still undertakes important observation missions to date.
Regarding data products, the most notable differences between Landsat 7 and Landsat 5 are: Landsat 7 adds a panchromatic band (PAN band) with a resolution of 15 meters; the data of Band 6 is divided into low-gain and high-gain datasets, and its spatial resolution is increased from 120 meters to 60 meters.
