本数据集为TM，Landsat4卫星的数据集，p116r051_4x19920914。轨道号：116；行号：051；数据时间：1992-09-14。<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 consists of TM (Thematic Mapper) data from the Landsat 4 satellite, with the product identifier p116r051_4x19920914. Path: 116; Row: 051; Data acquisition date: 1992-09-14.

Landsat is a series of Earth resources satellites developed by the United States. As a series of Earth observation satellite systems designed to detect Earth's resources and environment, it 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 placed into orbit. The launch attempt of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and still undertakes important operational missions to this day.

In terms of data product specifications, the most significant differences between Landsat 7 and Landsat 5 are as follows: First, a panchromatic band (PAN band) with a spatial resolution of 15 meters was added to Landsat 7; Second, the data for Band 6 is divided into low-gain and high-gain datasets, and its spatial resolution was improved from 120 meters to 60 meters.
