The World Factbook The Office of Public Affairs (OPA) is the single point of contact for all inquiries about the Central Intelligence Agency (CIA). We read every letter, fax, or e-mail we receive, and we will convey your comments to CIA officials outside OPA as appropriate. However, with limited staff and resources, we simply cannot respond to all who write to us. Contact Information The National Map The National Map is now offering a collection of small-scale datasets that can be downloaded for free. Although the 1997-2014 Edition of the National Atlas of the United States was retired in September 2014, The National Map recognizes the importance of continuing to make a collection of the small-scale datasets, originally developed for the National Atlas, available to users. Small-scale maps have an advantage over large-scale maps when there is a need to show a large area in a single view. This makes small-scale maps an ideal solution for scientists, decision-makers, and planners needing to provide a geographical context for the research projects.
s IceBridge Mission Contributes to New Map of Antarctica NASA's IceBridge Mission Contributes to New Map of Antarctica A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as Bedmap—that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation Satellite, known as ICESat, and ice thickness data collected by Operation IceBridge. These images depict the differences between Antarctica's ice sheet with its underlying topography. Click and drag the white bar to compare the images.

HARVARD Collection Digital Maps The Harvard Map Collection is one of the oldest and largest collections of cartographic materials in the United States with over 500,000 items. Resources range from 16th century globes to modern maps and geographic information systems (GIS) layers. A selection of our materials has been digitally imaged and is offered both as true picture images and georeferenced copies. This Virtual Collection includes those maps and atlases that are available through the Harvard Image Delivery Service. Those maps that have been georeferenced are available through the Harvard Geospatial Library. Therefore, many of the maps listed will have two records, one for the image that is true to the original and the other a georeferenced image.
