Placing marine cartography front and center
Presenter: Shachak Peeri, NOAA - Marine Chart Division
Cartography and Geographic Information Systems (GIS) are complementing sciences that merge map design concepts with the study of geometric properties and spatial relations. As NOAA transitions from raster-based paper chart production to vector-based electronic navigational charts and precision navigation, it is important to retain traditional concepts and best practices. This paper presents NOAA’s efforts to retain cartographic capacity within its ranks. Recently, the International Board on Standards and Competence for Hydrographic Surveyors and Nautical Cartographers recognized and approved Coast Survey’s new certification program in cartography. Also, NOAA personnel are becoming more active in national and international cartographic working groups and commissions.

Analyzing cartographic information to improve nautical chart coverage 
Presenter: Colby Harmon, NOAA - Marine Chart Division
The National Oceanic and Atmospheric Administration (NOAA) is undertaking a program to enhance and standardize its suite of Electronic Navigational Charts (ENC). ENCs, used by professional mariners and recreational boaters alike, were digitized in the 1990s from paper nautical charts having a variety of shapes, sizes and scales. A new scheme with a standardized, gridded layout has been proposed, based on criteria, such as existing U.S. and Canadian ENC coverage, the size of ports and positions port entry features, and vessel traffic volume. This presentation describes the criteria and the analytical methods used to create and validate the new scheme.

Future of Cartography: Deriving Raster Products using Vector Data
Presenter: Christie Ence, NOAA - Marine Chart Division
Nautical charts are an essential tool for marine navigation. Despite introduction of global positioning systems (GPS) and electronic navigational tools that present navigation data in a vector format on a display, paper charts are still the preferable choice for many mariners. With NOAA’s new plan to "standardized, consistent gridded framework" that is optimized for digital displays, the question is what is the future of paper charts?  In order to allow a raster-based maintenance system, it is now possible to translate encoding attributes of vector objects into standardized chart symbols and labels. Thus, simplifying workflow processes for paper and raster chart production.

Historical Perspective on Marine Cartography in the Last Days of Pen and Ink 
Presenter: John Macek, NOAA - Marine Chart Division
Historical Perspective on Marine Cartography examines the process by which nautical cartographers in the Marine Chart Division of the Office of Coast Survey updated their suite of products during the last decade of the 20th Century. The era was one of dynamic change, as advances in automation pushed desktop computing into the limelight, and the age of pen and ink on mylar faded away, eventually being supplanted by the development of the raster nautical chart. The lecture will also touch on the tasks performed by the various branches in the division, and address the fact that even though the cartographic tools changed, the cartographic rules remained the same.
