The USGS works collaboratively with Usgs eros map to enable powerful technical capabilities within a geographical context by targeting efforts in watersheds or basin-level Focus Area Studies, where the resulting tools and information can soon become the basis for monitoring and assessing water use Usgs eros map the Nation. Water use maps can allow insight into Penis nipples sex productivity, drought implications, and water budget analyses, which can amp surface and groundwater, and environmental flow. Orthoimagery data typically are high resolution aerial images that combine the visual Usts of an aerial photograph with the spatial accuracy and reliability of a planimetric map.

Science Explorer. Frequently Asked Questions. Multimedia Gallery. Park Passes. Technical Announcements. Employees in the News. Emergency Management. Scientists at EROS look at local and global drivers of land-use change to project how different scenarios will impact and change landscapes. Land-use change and the resultant changes in land cover impact a wide variety of ecological processes.
Projected land-cover data produced by EROS have been used for a wide variety of applications. Today, the U. During this year period, 7.
When a forest gives way to a potato field, when landscapes once teeming with wheat and barley disappear into seas of switchgrass, there are always implications.
Environmental implications. Economic ones. Land use change can affect local climate. It can alter biodiversity, even the quality of groundwater. Any number of new realities emerge when land—especially that used for agriculture— LCMAP will be used to explain how past, present, and future landscape change affects society and natural systems.
Here, we describe a Understanding the effects of management practices on soil organic carbon SOC is important for designing effective policies to mitigate greenhouse gas emissions in agriculture. In the Midwest United States, management practices in the croplands have been improved to increase crop production and reduce SOC loss since the s.

The collection of maps covers 93 regions across Antarctica with multiple versions for areas that have extensive aerial coverage. The Antarctic Flight Line Maps feature hand-drawn flight lines along with the frame numbers of aerial photographs taken during the flight. Navy for use in topographic mapping. TMA photography is a system of cameras positioned to take left oblique, vertical, and right oblique images simultaneously. Not all flights were equipped with oblique cameras, and equipment malfunctions limited the availability of complete sets of photography.
Flight lines continue to be cataloged by TMA number even though missions flown after January acquired images with a single vertical camera. Since the flight line information is approximate, images should be previewed online to determine whether the area of interest is covered. The files are stored in JPEG format. These sites may not be under active maintenance and may include outdated information.
An alphabetical list of map names based on geographic features can be used to search, preview, and save the Antarctic Flight Line Maps. A collection of aerial photographs over the Antarctic that is available for downloading as medium or high resolution digital images - EE supports the searching of satellite, aircraft, and other remote sensing inventories through interactive and textual-based query capabilities.

Employees in the News. Emergency Management. Back to Products Overview. Public domain. The photographs were taken with a 6-inch focal length lens at a scale of , Film type and extent of coverage were determined by available funds and operational requirements.
Photographs were acquired on 9-inch film and were centered over quarters of USGS 7. Black-and-white BW panchromatic film is sensitive to the full visible portion of the electromagnetic spectrum of light and captures images in tones of gray ranging from black to white. Color infrared CIR , or false color, film is sensitive to green and red in the visible portion of spectrum of light and extends into the near-infrared region of the spectrum.
Vegetation is distinctly red to magenta in CIR images because vegetation is highly reflective in the near-infrared portion of the spectrum. CIR photography uses high-speed film that is subject to degradation prior to processing, which can create an overall blue cast to the image. The scale of the image is the ratio of the distance on the image compared to the equivalent distance on the ground.
An image with a scale of , means that one inch on the photo is equivalent to 40, inches on the ground. A 9 x 9-inch image with a scale of , 1 inch equals about 0. Aerial photographs are acquired by aircraft equipped with mapping cameras. The recording technique for the NAPP film collection is vertical photography, which is obtained with the camera pointed directly at the ground.
Flight lines for the NAPP program were flown in a north-to-south direction through the east and west halves of 7. Commercial flight contractors were required to meet a stringent list of acceptance criteria in order to fulfill contract requirements. All photographs were manually assessed to ensure that they met the photographic, cartographic, coverage accuracy, and quality standards of the NAPP program. Even though the images in the NAPP collection met contract requirements, users should note that the images have not been geocorrected.
The images may have feature displacement and scale variation caused by differences in elevation, lens distortion, and camera tilt. Since the medium and high resolution digital products are reproductions of aerial photographs, any geometric inaccuracies in the original photograph are carried over into the digital products.
EarthExplorer offers the entire NAPP collection, which includes accepted photography as well as any other frames on the roll of film. Images have been captured as they appear on the roll of film and may need to be rotated to adjust the orientation. The medium resolution digital NAPP products were created with a digital single-lens reflex camera at a resolution of 63 microns, or dots per inch dpi.
