AmericaView Landsat Image Service Archive

NDVI land cover information for the State of Idaho produced from Landsat imagery. The site contains a number of white papers and demos explaining the source data and processing steps used to create the final land cover product. Produced by Idaho State University for IdahoView, a member of the AmericaView Consortium.

Accessing Landsat Imagery & Working With It in ArcGIS

A video tutorial produced for AmericaView by Jarlath O'Neil-Dunne, University of Vermont. The video demonstrates how to search for and download Landsat data from the USGS GloVis site, as well as how to load and display this multiband imagery in ArcGIS.

AVIRIS Flight Data Locator

AVIRIS (Airborne Visible / Infrared Imaging Spectrometer) from NASA provides imagery and hyperspectral radiance data in 224 contiguous spectral channels with wavelengths from 400 to 2500 nanometers at ~15 meter spectral resolution. They have a lot of holdings for downloading and an easy map to see what they have available.

Earth Explorer

Earth Explorer is a map-based web interface to a large number of data sets distributed by the USGS, including aerial photography, Digital Line Graph (DLG) and Digital Raster Graphic (DRG) products, SRTM digital elevation data, numerous land observation satellite data products (government and commercial), and landcover data products.

eCognition Community

The eCognition Community contains tutorials, sample rule sets and user questions.

Interagency Lidar Portal

The most comprehensive collection of lidar data for the United States.

LandsatLook Viewer

This map-based interface allows you to search for and download Level 1 Landsat Data products. Unlike EarthExplorer, the LandsatLook Viewer only provides access to LandsatLook (.jpg) files and corresponding Level 1 products. However, the image search and download interface displays full resolution seamless images. The search interface also allows you to specify the satellite/sensor, date, and percent cloud cover, and browse results before downloading.

Louisiana Statewide GIS Atlas

A searchable online geospatial database for the state of Louisiana, containing imagery, elevation data, and numerous GIS layers.

New York State GIS Clearinghouse

A searchable online geospatial database for the state of New York, containing imagery, elevation data, and numerous GIS layers.

Pennsylvania Spatial Data Access (PASDA)

A searchable online geospatial database for the state of Pennsylvania, containing imagery, elevation data, and numerous GIS layers.

QCoherent LP360 Lidar Tutorial Videos

Instructional videos produced by QCoherent on the processing of lidar data in LP360.

Remote Sensing I: Overview & Principles

A video tutorial by Jarlath O'Neil-Dunne, University of Vermont

Remote Sensing II: Processing, Feature Extraction, and Sensors

A video tutorial by Jarlath O'Neil-Dunne, University of Vermont

SpecTIR Hyperspectral Data Samples

Free hyperspectral data collected with the AISA airborne sensor are available on this site, including samples from the Lower Suwannee National Wildlife Refuge in the Gulf of Mexico, the Deepwater Horizon Oil Spill, agriculture and vegetation data from Beltsville, MD, geologic data from Cuprite, NV, and coral reef data from the Red Sea.

Texas GIS Data

A searchable online geospatial database for the state of Texas, containing imagery, elevation data, and numerous GIS layers.

USDA Geospatial Data Gateway

The Geospatial Data Gateway (GDG) is the online source for environmental and natural resources data maintained by the USDA Service Center Agencies (SCA); Natural Resources Conservation Service (NRCS), Farm Service Agency (FSA), and Rural Development (RD). Layers of particular interest are NAIP aerial photography, soils, and public land survey system data.

USGS Global Visualization Viewer (GloVis)

GloVis is a map-based web interface to aerial photography and satellite imagery archived at the USGS Earth Resources Observation and Science Center (EROS).

USGS Emergency Operations Portal

The U.S. Geological Survey (USGS) Emergency Operations, in support of the Department of Homeland Security, provides remotely sensed imagery for use in disaster preparations, rescue and relief operations, damage assessments, and reconstruction efforts. Satellite and aerial images for analysis of disaster areas before, during, and after a disaster are included in this database. There is a link on the Emergency Operations Portal homepage to HDDS, the Hazards Data Distribution System, where data can be accessed with both map and text-based search tools.

Virginia Geospatial Extension

The Virginia Geospatial Extension Program, hosted by Virginia Tech, has many useful resources for remote sensing and GIS professionals. They have created a series of helpful tutorial videos, posted on YouTube, that demonstrate basic tasks in ArcGIS.

Working with Landsat Data

This video provides a comprehensive overview of working with Landsat data in ArcGIS.
