Q: What is a historical chart?
A: Historical charts are nautical charts that contain older information.  Because these charts do not contain the latest safety information, we caution users against using these images for coastal and offshore navigation. 

Q: Can I buy a printed version of the chart?
A: NOAA's Office of Coast Survey does not print historical charts. We recommend contacting your local print shop, which should be able to provide those services with a downloaded copy of the JPG image on CD or web link to the image you require.

Q: What size are the scanned images?
A:The sizes of the charts and maps in the collection vary. When recorded in our database, we provide the document dimensions in the image preview as well as in a supplemental TXT file that accompanies each image download. The average size is 35 x 32 inches.

Q: Can I use these charts to navigate?
A: No! Historical Charts are Not for Navigation. Screen captures of Historical Charts do not fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations. For navigational charts, please visit the Office of Coast Survey website.

Q: Is usage of these images limited by copyright laws?
A: The images are in public domain, so they can be used for any purpose (except for navigation), free of charge. All that we ask is that you cite the website in some way. The preferred format for citation is as follows:
