Remote Sensing

What is Remote Sensing?

Remote sensing is the examination or the gathering of information about a place from a distance. Such examination can occur with devices (e.g. - cameras) based on the ground, and/or sensors or cameras based on ships, aircraft, satellites, or other spacecraft.  Today, the data obtained is usually stored and manipulated using computers. The most common software used in remote sensing is ERDAS Imagine, ESRI, MapInfo, and ERMapper.

Remote Sensing Resources

  • USGS EarthExplorer - The EarthExplorer user interface is an online search, discovery, and ordering tool developed by the United States Geological Survey (USGS). EarthExplorer supports the searching of satellite, aircraft, and other remote sensing inventories through interactive and textual-based query capabilities. Through the interface, users can identify search areas, datasets, and display metadata, browse and integrated vidual services within the interface.
  • UNEP Environmental Data Explorer - The Environmental Data Explorer is the authoritative source for data sets used by UNEP and its partners in the Global Environment Outlook (GEO) report and other integrated environment assessments. Its online database holds more than 500 different variables, as national, subregional, regional and global statistics or as geospatial data sets (maps), covering themes like Freshwater, Population, Forests, Emissions, Climate, Disasters, Health and GDP. Display them on-the-fly as maps, graphs, data tables or download the data in different formats.
  • USGS LandsatLook Viewer -  In honor of the 40th Anniversary of the Landsat 1 launch, and in preparation for Landsat 8 in February 2013, the USGS has rolled out a prototype viewer that allows easy access to the over 3 million scenes in the Landsat archive. The LandsatLook Viewer utilizes ArcGIS Server technology to enable comprehensive searching and downloading of full-resolution LandsatLook images, along with access to Level 1 Data Products.
  • USGS CLICK (Center for LIDAR information Coordination and Knowledge) - There has been increasing demand for research utilizing all information generated from lidar remote sensing data and not just bare earth digital elevation models (DEMs). While this technology has been a proven mapping tool, effective for generating bare earth DEMs,research on using the entire point cloud of this remote sensing data for scientific applications have been slowed by: The high cost of collecting lidar as well as a steep learning curve on research and understanding involving utilizing the entire point cloud. The goal of CLICK is to facilitate data access, user coordination and education of lidar remote sensing for scientific needs.
  • NAIP (National Agricultural Imagery Program) - The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition.
