p119r026_5x19900906-陆地卫星遥感影像

本数据集为TM，Landsat5卫星的数据集，p119r026_5x19900906。轨道号：119；行号：026；数据时间：1990-09-06。<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 Thematic Mapper (TM) dataset from the Landsat 5 satellite, with the identifier p119r026_5x19900906. The path number is 119, row number is 026, and the data acquisition date is 1990-09-06.
Landsat is a series of U.S. Earth resources satellites, which constitutes a series of Earth observation satellite systems dedicated to detecting 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 launched. The launch 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 products, the most notable differences between Landsat 7 and Landsat 5 are as follows: Landsat 7 adds a 15-meter resolution panchromatic band (PAN band); the data of Band 6 is divided into low-gain and high-gain datasets, with its resolution increased from 120 meters to 60 meters.
