Vector Shoreline of Tinian, CNMI, Derived from 2001 IKONOS Imagery

NOAA_NCEI provides a digital vector shoreline for Tinian in the Commonwealth of the Northern Mariana Islands. The shoreline was manually digitized from one-meter panchromatic IKONOS satellite imagery purchased in 2001. This data was created to support the Pacific Islands GIS project and coral mapping activities.

Use Cases

• Coastal change detection and monitoring based on the manually digitized, high-resolution shoreline.
• GIS base layer creation for environmental planning based on the accurate, up-to-date vector data.
• Coral reef habitat mapping and analysis based on the data's stated purpose for coral mapping activities.
• Validation and updating of existing shoreline datasets based on the derived vector data.

Strengths

• Shoreline derived from one-meter resolution panchromatic imagery, suggesting high spatial detail.
• Data was manually digitized, which may indicate careful human verification.
• Created for specific NOAA projects (Pacific Islands GIS and coral mapping), suggesting a defined purpose.

Limitations

• Last updated 2001-11-19 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.
