p129r060_5x19890723-陆地卫星遥感影像

本数据集为TM，Landsat5卫星的数据集，p129r060_5x19890723。轨道号：129；行号：060；数据时间：1989-07-23。<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 TM dataset from the Landsat 5 satellite, with the identifier p129r060_5x19890723. Path: 129; Row: 060; Data acquisition date: 1989-07-23.

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

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

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