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 NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian asNeeded IKONOS IKONOS multispectral imagery IKONOS panchromatic imagery Pacific Islands GIS Shoreline Shoreline data Shoreline vectorization land/water interface oceans vectorization theme Coastal Zone Oceania Territory of Guam United States place DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

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. Completeness Report 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. Conceptual Consistency 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. Cloud Cover for imagery was less than 10 percent. Process Date Range is 20020905 - 20030923 2003-09-23T00:00:00 Further modification of the Guam shoreline was conducted by staff within the Guam Coastal Zone Management Program and modified by staff of the NOS Biogeography Branch. 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 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 | Type of Source Media: CD-ROM 2835 Digital Ortho Quads for Agana, Agat, and Apra 1997-01-01 publication United States Geological Survey (USGS) 1997 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 Geospatial Form: map | Type of Source Media: CD-ROM 24000 Guam Digital Raster Graphic (DRG) 1998-02-26 publication United States Geological Survey http://mapping.usgs.gov WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 1998-02-26 Source Contribution: Used to identify and digitize the shoreline (land/water interface) for Guam | Source Geospatial Form: remote-sensing image | Type of Source Media: CD-ROM 3780 IKONOS Panchromatic Satellite Imagery 2003-01-16 publication Space Imaging Incorporated http://www.spaceimaging.com WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2000-10-17 2003-01-16
