This presentation focuses on a case study of river flooding in Reno, Nevada. However, the "how-to" information covered is applicable to any community that experiences disasters. Floods have negative impacts on people and businesses located in flood-prone areas, as well as on the finances of local governments. It's important for emergency management staff to have knowledge of current demographics of citizens who are at risk from flooding. Residents who are elderly, lack transportation, and have fewer financial savings and resources may require special emergency response measures. Decision-makers benefit from advance knowledge about the number of and current values of commercial and residential buildings located in flood-prone areas, because their losses could impact local governments' tax revenue.
This session discusses how GIS professionals can 1) perform overlay analyses of spatial and demographic data from federal and local sources to identify potential human and economic impacts of flooding and 2) create visualization products that show results in a format that emergency responders and decision-makers can easily understand. It covers using data from the 2010 Census and the American Community Survey. Users who are familiar with the 2000 Census data but not the 2010 data will benefit from learning about changes that have occurred. This presentation includes examples of 2-D and 3-D maps created using ArcGIS 10.
