p176r072_2x19790808-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p176r072_2x19790808。轨道号：176；行号：072；数据时间：1979-08-08。<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 refers to MSS data acquired by the Landsat 2 satellite, with the product code p176r072_2x19790808. The path number is 176, row number is 072, and the data acquisition date is 1979-08-08.

Landsat is a series of Earth resources satellites developed by the United States. It is a series of Earth observation satellite systems used for detecting Earth's resources and environment, and was formerly named Earth Resources Technology Satellite (ERTS).

Since the launch of Landsat 1 on July 23, 1972, by March 1, 1984, Landsat 5 had been successfully launched. The launch of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and it still undertakes important remote sensing missions to this day.

In terms of data products, the most significant 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.
