Landsat satellite image Download

How to download Landsat ImagesThis article will discussed about Landsat Satellite mission as well as process of downloading Landsat satellite image. LANDSAT MISSIONThis US (NASA and USGS) satellite remote sensing program was the first civil earth-observing satellite program. It started with the first Landsat satellite’s launch in 1972 and is continuing with Landsat 8, recently launched. Since June 2009, the entire Landsat image archive is available at no charge online (see website Earth Explorer from the U.S. Geological Survey). Landsat 7 Landsat 7 was launched in 1999 and is equipped with a multi-spectral sensor known as the Enhanced Thematic Mapper Plus or ETM+. The Enhanced Thematic Mapper Plus (ETM+), imitates the competencies of the highly successful Thematic Mapper instruments of earlier Landsats series. The ETM+ also have some additional features that make it a more resourceful and efficient instrument for global change studies, land cover monitoring and assessment, and large area …

Satellite Image Information- Details of Spatial and Spectral Resolution

Satellite Image Information:There are many types of satellite images available through download and purchase options, one can select from them as per need of their project. These satellite image can be selected based on different properties of satellite image such as Spatial resolution, spectral resolution, temporal resolution and swath of satellite image (that describe the scene size or coverage area). A satellite can use only visible part of electromagnetic energy and some satellite use both visible and infrared part of electromagnetic energy. This is usually referred by spectral resolutions or number of band recorded in particular satellite image. 
The list is provided to understand the satellite information and use in specific need as per satellite image specification. It has information of different satellite mission details with their properties such as bands, resolution and scene size. This information can be used to acquire satellite image as per your need of project or researc…
