本数据集为MSS，Landsat2卫星的数据集，p174r052_2x19781109。轨道号：174；行号：052；数据时间：1978-11-09。<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 an MSS dataset from the Landsat 2 satellite, with the identifier p174r052_2x19781109. The Path number is 174, Row number is 052, and the data acquisition date is 1978-11-09.

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

Since the launch of Landsat 1 on July 23, 1972, by March 1, 1984, the program had launched up to Landsat 5. The launch attempt of Landsat 6 failed. Landsat 7 was launched on April 15, 1999, and it still undertakes important Earth observation missions to this day.

The main differences between Landsat 7 and Landsat 5 data products are as follows: 1) Landsat 7 adds a 15-meter resolution panchromatic (PAN) band; 2) The data of Band 6 is divided into low-gain and high-gain datasets, with its spatial resolution improved from 120 meters to 60 meters.
