p186r035_2x19750821-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p186r035_2x19750821。轨道号：186；行号：035；数据时间：1975-08-21。<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 MSS data from the Landsat 2 satellite, with the identifier p186r035_2x19750821. Path: 186; Row: 035; Data acquisition date: 1975-08-21.
The Landsat program is a series of U.S. Earth resources satellites. It is a series of Earth observation satellite systems developed by the United States for detecting Earth's resources and environment, and was formerly known as the Earth Resources Technology Satellite (ERTS).
Since the launch of Landsat 1 on July 23, 1972, up to March 1, 1984, the program had launched satellites up to Landsat 5. The launch of Landsat 6 failed. Landsat 7 (Landsat-7) was launched on April 15, 1999, and it still undertakes important Earth observation missions to this day.
In terms of data products, the most notable differences between Landsat-7 and Landsat-5 are: the addition of a 15-meter spatial resolution panchromatic band (PAN band); the data of Band 6 is divided into low-gain and high-gain versions, with its spatial resolution increased from 120 meters to 60 meters.
