Vulnerable Schools, 2100

Frequently-anticipated questions:


What does this data set describe?

Title: Vulnerable Schools, 2100
Abstract:
This dataset shows schools that are vulnerable to a 100-year coastal flood event with a 1.4 meter sea-level rise in California (year 2100 scenario). The school data was extracted from the FEMA HAZUS model and was intersected with the flooding layers created by the Pacific Institute and USGS/SCRIPPS.
Supplemental_Information:
The school data was acquired from the FEMA HAZUS model for which information can be accessed at: <http://www.fema.gov/plan/prevent/hazus/>

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (132)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
