Satellite remote sensing data. Specially a wide array of satellite and aerial images a wide range of search criteria and the sequential arrangements of satellite imagery make the earth explorer a pro in terms of downloading imageries. Remote sensing is a key technique used to obtain information related to the earth s resources and environment what popularized satellite imagery data is that they can be easily accessed online through various mapping applications like google earth and bing maps. Special cameras collect remotely sensed images which help researchers sense things about the earth. To serve a wide user community by providing composite landsat images and raw data for urban areas that can be used in interdisciplinary studies of remote sensing and the environment.

Usgs earth explorer will stay the best portal for fetching remote sensing data for a variety of reasons. Remotely gathered data is available from a range of sources and data collection techniques and is often the only type of data that is not always easily found within the public domain. Through the land remote sensing policy act of 1992 the u s. The goal of the satellite remote sensing group is to apply remote sensing techniques to satellite data to further knowledge of sea surface temperature air sea interaction winds and water vapor.

Satellite remote sensing measuring entering and leaving flux of radiation from top of the atmosphere is one of the most powerful tools in climate change ecology. Remote sensing data acquired from instruments aboard satellites require processing before the data are usable by most researchers and applied science users. Urban extents from viirs and modis for the continental u s. This is largely due to the fact that most of this data is acquired by equipment that is expensive to build and maintain.

Congress directed the department of the interior doi to establish a permanent government archive containing satellite remote sensing data of the earth s land surface and to make this data easily accessible and readily available. Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance typically from satellite or aircraft.
