Connecticut Coastal Towns Vulnerability Index Dataset

Brief Description:

The dataset includes the GIS maps for the Coastal Vulnerability Index Viewer.

Dataset Content:

GIS shapefiles and the metadata for each contributor and contributor layer are given individually. The source files for all of them are linked separately. The dataset also includes a map package for all the contributor layers, all the vulnerability layers, and the weighted vulnerability layers separately.

Temporal Coverage:

The temporal coverage of each file depends on the period for all the source files. The datasets included in the study aims to cover either the most comprehensive or recent data to represent the current situation. Please refer to each metadata or summary file HERE.

Spatial Coverage:

All the shapefiles covers 24 coastal towns of Connecticut. The spatial resolution for each file depends on the source file resolution. The dataset included in the study aims to cover the highest available resolution of data. Please refer to each metadata or summary file HERE.

Update Schedule:

• Recently updated on February 10, 2020.
• Next update: May 2021

Usage Restrictions:

None

Detailed Description:

The maps represented here aimed to describe the vulnerability of different variables concerning climate change, particularly sea-level rise. The available datasets that are considered useful to represent overall vulnerability are gridded and ranked relative to each other. The ranks represent very low vulnerability (1) to very high vulnerability (5) to represent the data in the index-based format.

The shapefile grids given below are ranked considering all the Connecticut coastal towns. If the relative vulnerability of a specific region needs to be visualized, the user should normalize the geomean attribute according to that region boundary.
