Vectorized Shoreline of Tinian, Commonwealth of the Northern Mariana Islands, Derived from IKONOS Imagery, 2001

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 da...

IKONOS影像数据系为支持太平洋岛屿地理信息系统（GIS）项目和海洋服务局（NOS）的珊瑚测绘活动而采购。每个研究区域均购买了单米波段的彩色影像和四米波段的多光谱数据。通过从单米波段的彩色影像中手工数字化生成，得到了精确且时效性强的海岸线矢量数据。
