Remote sensing

Google Earth Engine

Google Earth Engine provides access to several petabytes of satellite imagery and geospatial datasets. Researchers can write their own algorithms or reuse available algorithms online to perform analyses. Users must request access.

Planet.com

What is it?


Planet.com is a website where U of T students, staff, and faculty can download satellite imagery of the earth. Use Planet.com to view regional change over time (daily, weekly, monthly, quarterly). Several kinds of imagery, including 3 and 4-band (NIR), are included. There are also some forms of on-the-fly spatial analysis available.


Great Lakes Information Network (GLIN)

Discover, publish, and acquire geospatial data for areas within the Great Lakes region. The GLIN has a portal for viewing and exploring the Great Lakes and associated data layers, a data portal through which GIS and geospatial data for the Great Lakes can be published and acquired, and a gallery of downloadable images depicting Great Lakes geophysical data. The majority of the data are available for download at no cost.

USGS LandsatLook Viewer

LandsatLook Viewer allows searching and downloading of LandsatLook Images. LandsatLook Images are full resolution .jpg files that are included as options when downloading Landsat data from EarthExplorer or GloVis. Images are useful for image selection and visual interpretation. The majority of the data are available for download at no cost. See list of data products.

Hazards Data Distribution System (HDDS)

The USGS Emergency Operations, in support of the Department of Homeland Security, provides these images for use in disaster preparations, rescue and relief operations, damage assessments, and reconstruction efforts. HDDS supplies satellite and aerial images for analysis of disaster areas before, during, and after a disaster.  Access disaster response imagery in predefined tiled downloads. The majority of the data are available for download at no cost.

USGS Land Remote Sensing Program

The Land Remote Sensing Program provides the Federal Government and the public with a primary source of remotely sensed data and applications. Products and data available include aerial photography, digitized maps, elevation products, land cover, and satellite imagery. The majority of the data are available for download at no cost except for higher resolution film scans.

Global Change Master Directory

The Global Change Master Directory is an extensive directory of descriptive and locational information about data sets and services relevant to global change research. The project mission is to assist researchers, policy makers, and the public in the discovery of and access to data, related services, and ancillary information (which includes descriptions of instruments and platforms) relevant to global change and Earth science research.  The majority of the data are available for download at no cost.
