This project calculated average water depth by zip code zone for New Orleans right after Katrina.
Input data set was a table of LiDAR points with geographic coordinates and water depths. The technical challenge was the number of points to process - more than 26 million points for 37 zip code zones in 535 square miles.
The normal spatial statistics method would fail due to prolonged computing time. The work-around was to break the points by zones and calculate statistics per zone.
The ROAD data includes election returns, socioeconomic summaries, and demographic measures of the American public. It includes every election at and above State House, along with party registration and other variables, in each state for the roughly 170,000 precincts nationwide. The geographic unit of ROAD is based on the Census Bureau defined Minor Civil Divisions (MCD).
The CGA created maps of actual and hypothetical congressional districts for comparison. The maps of actual districts use the 106th Congressional District Boundaries obtained from the U.S. Census Bureau. The maps of hypothetical congressional districts are generated from lists of coordinate pairs provided by the researchers. Each coordinate pair is intended to represent a Census Block Group centroid.
