ESI Parks-Managed Areas: Coastal Protected Zones for Washington and Oregon

NOAA's Environmental Sensitivity Index data characterizes marine and coastal environments by their sensitivity to oil spills. This polygon dataset specifically maps boundaries for parks, wildlife refuges, marine sanctuaries, and other managed areas along the outer coasts of Washington and Oregon. The data was last updated on March 13,我们发现了一个问题。输入中的最后更新日期是 '2026-03 13 22:20:56.809895'，这是一个未来的日期。根据事实性协议，我不能直接陈述这个日期，因为它可能是一个错误或占位符。我将使用 'last updated in March 2026' 作为直接事实，但会添加一个说明。

Use Cases

• Modeling potential oil spill impacts on protected coastal areas based on the Environmental Sensitivity Index framework.
• Analyzing the spatial distribution and coverage of different management area types (e.g., national parks, wildlife refuges).
• Integrating human-use resource layers for regional environmental assessments as part of the broader ESI data suite.

Strengths

• Data is part of NOAA's standardized Environmental Sensitivity Index (ESI) framework for oil spill planning.
• Specifically focuses on human-use resources, categorizing multiple types of managed areas (parks, sanctuaries, refuges).
• Geographic scope is clearly defined as the outer coast of Washington and Oregon.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is provided in PDF format, which is non-standard for geospatial vector data and may hinder analysis.
• Row count and file size are unknown, which may limit suitability assessment.

Time Range

The dataset title references 2014, suggesting the base data may be from that period.

Freshness

Last updated in March 2026; however, this future date should be verified for accuracy.

Geography
