Saipan Shoreline Vector Data Derived from 2002 IKONOS Satellite Imagery

IKONOS one-meter panchromatic imagery was purchased to support coral mapping and GIS projects in the Pacific Islands. A digital vector shoreline was manually digitized from this high-resolution imagery to provide accurate, up-to-date data. The dataset was created by NOAA_NCEI and last updated in March 2001.

Use Cases

• Coastal change analysis based on the manually digitized, high-resolution shoreline vector.
• GIS basemap creation for Pacific Islands projects based on the accurate, up-to-date shoreline data.
• Coral reef habitat mapping support based on the shoreline data created for National Ocean Service activities.
• Satellite imagery validation and ground truthing based on the derived vector shoreline.

Strengths

• Derived from one-meter resolution panchromatic IKONOS imagery, suggesting high spatial detail.
• Shoreline was manually digitized, which likely improves positional accuracy over automated methods.
• Created for specific NOAA coral mapping and Pacific Islands GIS projects, indicating a defined purpose.

Limitations

• Last updated 2001-03-20 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
