Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), NOAA Coastal Services Center (CSC) 20020923 first vector digital data Charleston, SC NOAA's Ocean Service, Coastal Services Center (CSC) The vectorized shoreline data was derived from the one-meter panchromatic IKONOS imagery. Those areas of the coastline that were obscured by cloud cover were derived from United States Geological Survey (USGS) Digital Raster Graphics (DRGs). http://ccma.nos.noaa.gov/ecosystems/coralreef/us_pac_terr/default.aspx 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 Terriiories 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. 20011119 ground condition Complete As needed 145.120642 145.291059 14.200756 14.109991 None Shoreline Shoreline data land/water interface vectorization Shoreline vectorization IKONOS IKONOS panchromatic imagery IKONOS multispectral imagery Pacific Islands GIS CoRIS Discovery Thesaurus Geographic Information > Shorelines CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Coastal Processes > Shorelines ISO 19115 Topic Category elevation 006 None United States Commonwealth of the Northern Mariana Islands Rota Coastal Zone Oceania CoRIS Place Thesaurus OCEAN BASIN > Pacific Ocean > Western Pacific Ocean > Rota Island > Rota Island ( Luta ) (14N145E0007) COUNTRY/TERRITORY > Northern Mariana Islands > Rota > Rota Island ( Luta ) (14N145E0007) CoRIS Region CNMI none Data set is not for use in litigation.

All arcs were snapped by the nodes to create consistently tied strings without node dangles. Line geometry is topologically clean. This shoreline dataset of Rota, 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. The data were created by delineating the shoreline off of IKONOS panchromatic digital satellite imagery collected in 2001. 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, 21 ground control points were used to determine the circular error (CE) at a 90% confidence level. For Pacific Islands, Rota, Commonwealth of the Northern Mariana Islands, IKONOS data, 2002 the circular error is 4.8 meters for the Panchromatic data set.

United States Geological Survey 19980226 map Reston, VA USGS http://mapping.usgs.gov 24000 CD-ROM 19980226 ground condition USGS DRGs 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. 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. Areas of the shoreline that were obscured by cloud cover were digitized from USGS DRGs. All lines are coded with length, ID, origin, and source Note - The USGS DRGs for Rota had to be adjusted in the x and y directions using ERDAS Imagine 8.5 to match the IKONOS imagery. This shoreline was produced during a two year period ending 20030923. 20020923 NOAA Coastal Services Center Pacific Islands GIS Specialist mailing and physical address
