p022r020_1x19730830-陆地卫星遥感影像

本数据集为MSS，Landsat1卫星的数据集，p022r020_1x19730830。轨道号：022；行号：020；数据时间：1973-08-30。<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 acquired by the Landsat 1 satellite, with the product identifier p022r020_1x19730830. Path: 022; Row: 020; Data acquisition date: 1973-08-30.
The Landsat series, formerly known as the Earth Resources Technology Satellite (ERTS), is a series of Earth observation satellite systems developed by the United States for Earth resource and environmental exploration and monitoring.
Since the launch of Landsat 1 on July 23, 1972, up to March 1, 1984, the United States had launched five Landsat satellites up to Landsat 5. The launch of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and has remained in active service performing critical missions to this day.
Regarding its data products, the most notable differences between Landsat 7 and Landsat 5 are as follows: Landsat 7 adds a 15-meter-resolution panchromatic (PAN) band; For Band 6, the data is divided into low-gain and high-gain datasets, and its spatial resolution is upgraded from 120 meters to 60 meters.
