p029r042_2x19790506-陆地卫星遥感影像

本数据集为MSS，Landsat2卫星的数据集，p029r042_2x19790506。轨道号：029；行号：042；数据时间：1979-05-06。<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 Multi-Spectral Scanner (MSS) dataset acquired by the Landsat 2 satellite, with the product identifier p029r042_2x19790506. The path number is 029, row number is 042, and the data acquisition date is 1979-05-06.
Landsat, previously named the Earth Resources Technology Satellite (ERTS) in its early stage, is a series of U.S. Earth resources satellites. It constitutes a suite of Earth observation satellite systems developed by the United States for detecting and monitoring Earth's resources and environment.
Since the launch of Landsat 1 on July 23, 1972, up to March 1, 1984, a total of five Landsat satellites (up to Landsat 5) had been successfully launched. The launch attempt of Landsat 6 ended in failure. Landsat 7 was launched on April 15, 1999, and continues to perform critical Earth observation missions to the present day.
In terms of data product specifications, the most notable differences between Landsat-7 and Landsat-5 are: A 15-meter spatial resolution panchromatic (PAN) band was added; the Band 6 data is divided into low-gain and high-gain datasets, with its spatial resolution increased from 120 meters to 60 meters.
