The Impacts of Sea-Level Rise on the California Coast: GIS Data Downloads

This page contains links to downloadable geographic data created or modified by Pacific Institute researchers for the project Impacts of Sea Level Rise on the California Coast.

These are not maps. They are data files, created for use by Geographic Information System (GIS) software. You will need a GIS application package capable of importing the data. A free data viewer, ArcExplorer, capable of displaying the data is available from ESRI at www.esri.com. There are also a number of open-source programs available, such as Quantum GIS (www.qgis.org).

Each dataset includes descriptive metadata, or information about the data.
The metadata describes how and when and by whom a particular set of data was collected, and how the data is formatted.

Your may use or redistribute these data for free. Please reference the Pacific Institute as the originator of the dataset in any future products or research derived from these data. If you re-distribute this data, please include the original metadata and source attribution.

This information is being made available for informational purposes only. Users of this information agree by their use to hold blameless the State of California, and its respective officers, employees, agents, contractors, and subcontractors for any liability associated with its use in any form. This work shall not be used to assess actual coastal hazards, insurance requirements, or property values and specifically shall not be used in lieu of Flood Insurance Studies and Flood Insurance Rate Maps issued by the Federal Emergency Management Agency (FEMA).
