p181r016_4x19830727-陆地卫星遥感影像

本数据集为MSS，Landsat4卫星的数据集，p181r016_4x19830727。轨道号：181；行号：016；数据时间：1983-07-27。<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 MSS data from the Landsat 4 satellite, with the product identifier p181r016_4x19830727. The path number is 181, row number is 016, and the data acquisition date is 1983-07-27.

The Landsat series, previously designated as the Earth Resources Technology Satellite (ERTS), is a suite of Earth observation satellite systems developed by the United States for Earth resource and environmental exploration.

Since the launch of Landsat 1 on July 23, 1972, by March 1, 1984, a total of five Landsat satellites had been launched. The launch of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and still performs critical Earth observation missions to this day.

The primary differences between Landsat 7 and Landsat 5 in terms of data products are: Landsat 7 includes a 15-meter resolution panchromatic band (PAN band); the data for Band 6 is split into low-gain and high-gain datasets, with its spatial resolution improved from 120 meters to 60 meters.
