Guide to how aerial photographs and satellite images are obtained and used. Includes information for ordering photographs and satellite imagery.

Frequently asked questions about obtaining and using aerial photos from the U.S. Geological Survey, including the ever-popular question, "Will I be able to see my house?"

Describes photographic projects from the USGS, other federal, state, and local government agencies, and commercial firms and includes a checklist for obtaining an aerial photograph.

This spectacular “blue marble” image from NASA is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet displayed at a very high resolution of 500 meters/pixel. These monthly images, which are freely available to educators, scientists, museums, and the public, reveal seasonal changes to the land surface: the green-up and dying-back of vegetation in temperate regions such as North America and Europe, dry and wet seasons in the tropics, and advancing and retreating Northern Hemisphere snow cover.

EarthExplorer (EE) provides online search, browse display, metadata export, and data download for earth science data from the archives of the U.S. Geological Survey (USGS). EE provides an enhanced user interface using state-of-the-art technologies for searching, viewing, and downloading data.

Timely access to global environmental data from satellites and other sources. Provides satellite products, environmental information, and official assessments of the environment in support of societal and economic decisions.

Continuous data from satellites like TOPEX/Poseidon and Jason help us understand and foresee the effects of the changing oceans on our climate and on catastrophic climate events such as El Niño and La Niña.

Digital data available through TNRIS pertain to water resources, geology, Census, and other natural resources spatial data. Digital Orthophoto Quads (DOQs) provide the most current view of surface features and are available in resolutions from 30 meters to one meter. You can also download 2.5 meter DOQQs, DRGs, TxDOT, DEMs, Hillshades, and more as they become available.
