Product DescriptionSurvey Photography is a large and diverse group of aerial photos from within the U.S. Geological Survey (USGS) National Center for Earth Resources Observations and Science (EROS) historical film archives. The photos date from 1940 to present, and they were originally acquired by a wide variety of sources such as NASA, EPA, BLM, U.S. Air Force, U.S. Navy, and others. Survey Photography is not a standardized product, and individual photos will vary in scale, size, quality, and coverage. This film is archived and produced as individual rolls and frames. Photos will be available in black & white (B/W), color, or color infrared (CIR), depending on source. Although the majority of these aerial photos were taken from a vertical perspective, some photos were taken from an oblique aerial view. Additional Information:
USGS Fact Sheet Camera Calibrations Survey Photography Metadata (pipe-delimited text file) Survey Photography Abstract Back to TopDigital File SizesHigh resolution Scanned - *.TIFF images:
** Color/CIR film source is not available at a 7 micron spot size because the file size is too large and/or there are no advantages below the 14 micron spot size. The above sizes may vary due to scanning more than just image data. With our policy to scan the surrounding metadata and the addition of the USGS logo the actual image size will generally be larger than the estimates above. Medium Resolution Digitized - *.TIFF images: The file sizes are approximately 15 megabytes for black and white images and 40 megabytes for color images. The files are stored in a TIFF format. The medium-resolution files are created at approximately 600 dpi. High Resolution Scanned: $24.00 per frame
The following table describes the maximum stacking limits (the number frames can fit on a particular CD or DVD media). The stacking limits are based on three criteria: Film Source Size, Micron Size and Film Image Type (B/W or Color/CIR). Medium Resolution Digitized: $1.00 per frame
High Resolution Scanned: Survey photography can be searched and ordered Earth Explorer. Medium Resolution Digitized: Once Survey Photography imagery has been digitized, products can be ordered on Earth Explorer With the current scheduling of the Medium Resolution Digitized product, NAPP images will be digitized first, followed by NHAP and other USGS agency Survey Photography projects. At this time, only 9 x 9 inch Survey Photography will be available as a digitized product. Contact USGS/EDC Customer Services for further information. Other sources for searching and ordering: |
