Shoreline Mapping Program: High-Resolution Vector Shoreline of Sarigan Island

NOAA's National Geodetic Survey provides a high-resolution vector shoreline for Sarigan Island in the Northern Mariana Islands. The data is compiled from imagery and structured using the C-COAST attribution scheme for GIS compatibility. This resource is part of the Coastal Mapping Program and was last updated in March 2026.

Use Cases

• Coastal change analysis based on the high-resolution shoreline vector data.
• GIS layer integration for environmental planning based on the described line and point shapefiles.
• Shoreline data standardization efforts based on the C-COAST attribution scheme mentioned in the description.

Strengths

• Data is described as 'accurate high-resolution shoreline'.
• Attribution follows the C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.
• Last updated on 2026-03-13, indicating recent maintenance.
