Geoinformatics

In response to steady increases in annual flood damage, the City of Indianapolis and the Indianapolis Museum of Art (IMA) funded a pilot project to determine whether recent enhancements to geospatial technologies and web delivery systems could provide accurate and rapid information about real-time or potential flood losses.

We worked with the U.S. Geological Survey (USGS) Indiana Water Science Center and the Indiana Silver Jackets to study a reach of the White River in Indianapolis that extends from the Ravenswood neighborhood to the IMA Virginia B. Fairbanks Art and Nature Park.

The project used a composite of diverse applications and Web services to integrate geospatial data and create real-time flood maps and estimates of building losses based on building type and water depth.

How it Works

The web-based application was designed to create real-time flood maps to determine building losses. The USGS Multi-Dimensional Surface-Water Modeling System (MD_SWMS) overlays the flood inundation grids with parcel-level property data to calculate the damage sustained to each property.
