p118r075_2x19781002-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p118r075_2x19781002。轨道号：118；行号：075；数据时间：1978-10-02。<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 acquired by the Landsat 2 satellite, with the product identifier p118r075_2x19781002. Its track number is 118, row number is 075, and the data acquisition date is 1978-10-02.
Landsat, formerly known as the Earth Resources Technology Satellite (ERTS), is a series of U.S. Earth resources satellites, which represent a suite of Earth observation satellite systems developed for detecting Earth's resources and environment.
Since the launch of Landsat 1 on July 23, 1972, by March 1, 1984, the Landsat series had launched up to Landsat 5. The launch of Landsat 6 failed. Landsat 7 (Landsat-7) was launched on April 15, 1999, and has continued to undertake important Earth observation missions to this day.
In terms of data product specifications, the most notable differences between Landsat-7 and Landsat-5 are: 1) A 15-meter resolution panchromatic band (PAN band) was added; 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.
