IKONOS imagery was purchased to support the Pacific Islands Geographic Information System (GIS) project and the National Ocean Service's (NOS) coral mapping activities. One-meter panchromatic and four-meter multispectral data were purchased for the Territory of Guam. A digital vector shoreline was manually digitized from the one-meter panchromatic imagery to provide accurate, up-to-date shoreline data for the region. The Pacific Islands Geographic Information System (GIS) project is a multiyear initiative designed to increase the use of GIS and related spatial technology in the coast resource management programs of the Territories of American Samoa and Guam, the Commonwealth of the Northern Marian Islands (CNMI), and the State of Hawaii. The project will focus on personnel, training, equipment, software, data, and applications. Where appropriate, other related activities in the region will be incorporated into the effort. completed National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program Biogeography Team Leader, Mapping Manager 301-713-3028 301-713-4388 1305 East West Highway Silver Spring MD 20910 tim.battista@noaa.gov pointOfContact asNeeded CoRIS_Metadata theme NCEI Geoportal Filter Mapping the shallow-water coral reef ecosystems of American Samoa, Guam, and the Northern Marianas 1209 project CRCP Project Shoreline Shoreline data land/water interface vectorization Shoreline vectorization IKONOS IKONOS panchromatic imagery IKONOS multispectral imagery Pacific Islands GIS theme None Geographic Information > Shorelines theme CoRIS Discovery Thesaurus EARTH SCIENCE > Oceans > Coastal Processes > Shorelines theme CoRIS Theme Thesaurus United States Territory of Guam Coastal Zone Oceania place None OCEAN BASIN > Pacific Ocean > Western Pacific Ocean > Guam > Guam (13N144E0000) COUNTRY/TERRITORY > United States of America > Guam > Guam (13N144E0000) place CoRIS Place Thesaurus Guam place CoRIS Region Users must assume responsibility to determine the appropriate use for these data.

The horizontal resolution of the digital imagery is 1 meter. The original scale of the imagery was 1:3780. During orthorectification of the IKONOS imagery, 73 ground control points were used to determine the circular error (CE) at a 90% confidence level. For Pacific Islands, Guam, IKONOS data, 2002 the circular error is 8.5 meters for the panchromatic data set. This shoreline dataset of Guam is dependent on the shoreline as delineated on 2001 through 2003 IKONOS digital satellite imagery from Space Imaging, LLC. The position of the shoreline might change as the natural land changes or better maps and more recent imagery become available. These data are believed to be logically consistent, though no tests were performed. All arcs were snapped by the nodes to create consistently tied strings without node dangles. Line geometry is topologically clean. During the vectorization process, the satellite imagery was displayed on a computer screen using ESRI's ArcGIS 8.2 software. In order to obtain the highest degree of accuracy from the imagery, the one-meter panchromatic imagery was used as a base layer for digitizing. In an effort to better visualize the land-water interface, the one-meter imagery was overlaid on top of the four-meter multispectral imagery using a 35 % transparency value. The near-infrared band (Band 4) was used in the display of the multispectral imagery. The resultant base layer contained the one-meter resolution of the panchromatic imagery and the colorization of the four-meter imagery. The display was zoomed to the image resolution of the panchromatic imagery and the shoreline was manually digitized. All lines are coded with length, ID, origin, and source. Note - Areas of the shoreline that were obscured by cloud cover in the satellite imagery were digitized from USGS Digital Raster Graphics (DRGs). The USGS DRGs for Guam were adjusted in the x and y directions using ERDAS Imagine 8.5 to match the IKONOS imagery. IKONOS imagery used were collected 20001017, 20001130, 20010511, 20010511, 20010514, 20021111, 20021114, 20030105, 20030116.

ArcView 3.2 was used to adjust shapefile vector vertices. Most alterations were done by combining the visual information available within the one-meter panchromatic imagery of Guam together with local knowledge of the coastline, and some Digital Ortho Quad (USGS DOQ) data. 2003-10-13T00:00:00 James Byrne Guam Coastal Management Program 671-472-4201 671-477-1812 P.O Box 2950 Hagatna Guam 96932 USA jbyrne@mail.gov.gu processor Source Contribution: Used to identify and digitize the shoreline (land/water interface) for Guam Source Type: CD-ROM 3780 IKONOS Panchromatic Satellite Imagery 2000-10-17 publication Space Imaging Thornton CO publisher Space Imaging Incorporated originator imageDigital 2000-10-17 2003-01-16 Source Contribution: Used to identify and digitize the shoreline (land/water interface) for areas of the coast that were obscured by cloud cover in the satellite imagery Source Type: CD-ROM 24000 Guam Digital Raster Graphic (DRG) 1998-02-26 publication USGS Reston VA publisher United States Geological Survey originator mapDigital 1998-02-26 Source Contribution: Used to identify and digitize the shoreline (land/water interface) for locations where the coast was obscured by cloud cover in the satellite imagery Source Type: CD-ROM 2835 Digital Ortho Quads for Agana, Agat, and Apra 1997-01-01 publication United States Geological Survey Reston VA publisher United States Geological Survey (USGS) originator USGS Digital Ortho Quads were supplied by the National Park Service. 1997-01-01 annually This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
