Those areas of the coastline that were obscured by cloud cover were derived from United States Geological Survey (USGS) Digital Raster Graphics (DRGs) 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 multi-spectral data were purchased for each study area. A digital vector shoreline was manually digitized from the one-meter panchromatic imagery to provide accurate, up-to-date shoreline data. 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 coastal resource management programs of the Territories of American Samoa and Guam, the Commonwealth of the Northern Mariana 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 Commonwealth of the Northern Mariana Islands Oceania Saipan 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, 23 ground control points were used to determine the circular error (CE) at a 90% confidence level. For Pacific Islands, Saipan, Commonwealth of the Northern Mariana Islands, IKONOS data, 2002 the circular error is 7.2 meters for the Panchromatic data set. Completeness Report This shoreline dataset of Saipan, CNMI, is dependent on the shoreline as delineated on 2001 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 current aerial photography 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 were digitized from USGS DRGs. The USGS DRG for Saipan had to be 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 - 20020923 2002-09-23T00:00:00 Further modification of the Saipan island outline was conducted by staff within the Coastal Resources Management Office, Saipan CNMI. 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 Saipan together with local knowledge of the coastline in those areas. A "Note" column was added to the data set and "local knowledge" was added in that column to denote those changes. In one area near the marina there was geometrically correct aerial photography available so this was used, and "air photo" was placed in the Note column. Metadata was updated using ArcGIS 8.2 software.Process Date Range is 20020930 - 20021015 2002-10-15T00:00:00 Source Contribution: Used to identify and digitize the shoreline (land/water interface) for Saipan. | Source Geospatial Form: remote-sensing image | Type of Source Media: CD-ROM 3780 IKONOS Panchromatic Satellite Imagery 2001-03-20 publication Space Imaging Incorporated http://www.spaceimaging.com WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2001-03-09 Source Contribution: Used to identify and digitize the shoreline (land/water interface) for area of the coast that were obscured by cloud cover in the satellite imagery. | Source Geospatial Form: map | Type of Source Media: CD-ROM 24000 Saipan 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
