本数据集为MSS，Landsat1卫星的数据集，p145r042_1x19740126。轨道号：145；行号：042；数据时间：1974-01-26。<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 a Landsat 1 satellite dataset (utilizing the MSS sensor) with the identifier p145r042_1x19740126. Its path number is 145, row number is 042, and the data acquisition date is 1974-01-26.

The Landsat series, formerly named the Earth Resources Technology Satellite (ERTS), is a suite 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, Landsat satellites 1 through 5 had been successfully deployed. The launch attempt of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and still performs critical remote sensing missions to date.

In terms of data products, the most prominent differences between Landsat 7 and Landsat 5 are as follows: Firstly, Landsat 7 adds a 15-meter-resolution panchromatic band (PAN band); Secondly, the data for Band 6 is divided into low-gain and high-gain datasets, with its spatial resolution improved from 120 meters to 60 meters.
