=2= Example Grid Maps

The series of two maps shows the area south of the City of Lake Charles in Southwest Louisiana as it is subject to storm surge resulting from hurricanes and sea level rise resulting from global warming.

The maps are examples of a compressive set of 117 that shows flooding along the Louisiana Gulf Coast from Texas to Mississippi. The format of the maps shows the same major grid with in two different ways. On the right hand side of a book page, the map shows cultural features (schools, hospitals, etc) subject to storm surge. On the left hand side  of a book page, the same area shows physical features (soil types, river basins, etc) subject to sea level rise. 

The bottom of each map shows descriptive features and statistics.

The cultural features are taken from the 2010 US Census Bureau enumeration and the census estimates from the 2017 for population, race and sex, housing units, family structure, income, public welfare, and education. The statistics are summed from  centroids of the part of the census tract (census block group), which fall within the major grid. 

The physical features are selected from a point that falls at the center  of the grid. These features include river drainage basins, the nearest stream within that basin, ecological area, and the soil type association.

An explanation of how these maps fits into a larger research project is discussed here.
