Satellite AIS Vessel Pressure Maps for Marine Spatial Planning in Congo

Featuring spatial data layers derived from Satellite Automatic Identification System (S-AIS) data for the Republic of Congo's exclusive economic zone. It includes fine-scale (0.05 km2 resolution) metrics like vessel intensity and occupancy to map shipping pressure. The data was used to analyze vessel traffic, revealing that four vessel types account for 93.7% of all traffic and operate across 92% of the EEZ.

Use Cases

• Generate vessel pressure maps using the intensity and occupancy spatial data layers to identify areas of high shipping activity.
• Analyze patterns of vessel behavior across different sectors (e.g., passenger vessels, tankers) to assess potential conflict with other ocean-user groups like fisheries.
• Support marine spatial planning by visualizing the spatial distribution of merchant shipping to fill gaps in ocean observation data.
• Calculate the combined operational area of major vessel sectors within the exclusive economic zone to quantify maritime domain use.

Strengths

• Provides fine-scale spatial data at 0.05 km2 resolution for detailed analysis.
• Based on publicly accessible satellite-derived AIS data, offering a mechanism to address data gaps.
• Analysis covers a national scale, specifically the Republic of Congo's exclusive economic zone.

Limitations

• The dataset's temporal coverage and update frequency are not specified, limiting time-series analysis.
• Geographic scope is limited to a single country (Republic of Congo), reducing generalizability.
• Specific data volume (rows, file size) and exact column structure are unknown, complicating technical assessment.
