Metadata Compilation, Including Geographic
Locations, of NOAAs Scanned Historical Maps and
Surveys Proposed Continuation of I-10 with
Modifications
2
Metadata for the Great Lakes Surveys

• 2,500 scanned images need to be catalogued
• Requires information contained within the title
  block and minimum and maximum latitude and
  longitude values for each image

3
Rename and Index Images from NARA

• Images represent early NOAA history and include
  boundary maps, Civil War maps, charts, sketches,
  instrument diagrams, 3-D bathymetric models, and
  more!

• 6,000 scanned images need to be renamed and
  catalogued, some are duplicate records in JPG and
  TIF
• Map and chart images will be available free to
  the public over the Internet at
• http//www.nauticalcharts.noaa.gov

4
Geo-referencing of NARA Images

• A fraction of the NARA images contain geographic
  positioning information

• Of the 6,000 scanned images, half are believed
  to be maps and charts with latitude and longitude
  and require the collection of geo-referencing
  information

• Why geo-referencing?
• To expand access and allow online searches by
  location and/or geographic place name

5
Geo-referencing of the Historical Maps and
Charts (continued)

• Over 35,000 (and counting) maps and charts from
  the late 1700s to the present
• Images available free to the public over the
  Internet at
• http//www.nauticalcharts.noaa.gov

• Includes some of the nation's earliest maps and
  charts, such as
• Nautical and aeronautical charts
• Civil War battle maps
• Gravity and isogonic maps
• Bathymetric and topographic maps
• City plans, and more!

6
Why Geo-referencing?

• Requires the collection of minimum and maximum
  latitude and longitude values for each image

• To improve online interface and enhance search
  capabilities and discovery methods based on
• Location
• Geographic Name

7
Overall Status and Request

• GREAT LAKES SURVEYS
• 2,500 scans of Great Lakes Surveys are at IMC
• Request to collect metadata, including
  geo-referencing, for each image in FY09
• NOAA ASSETS FROM NATIONAL ARCHIVES
• 6,000 scans of NOAA assets from National
  Archives need to be renamed and catalogued
• Request to collect metadata, including
  geo-referencing, for each image in FY09.
• Many images do not have latitude/longitude
  therefore, only about 50 of the images require
  geo-referencing
• NOAA HISTORICAL MAP AND CHART COLLECTION
• 8,000 images of online Historical Map and Chart
  Collection contain errors in NOAA auto-populated
  geo-referencing fields
• Original project (L-38), which covered
  geo-locations for 10,000 images, will be
  completed by IMC in FY08 with some money
  remaining
• 300 of 8,000 images with geo-referencing errors
  will be recaptured with extra FY08 funding
  under L-38.
• 7,350 images that will be uploaded to the
  online Historical Map and Chart Collection are
  missing geo-referencing information
• Request to collect geo-referencing information
  for all scans described above.
• RECOMMENDED FUNDING
• Recommend funding in FY 2009 at 150 of 08
  funding to possibly complete work.
