 Spatial Analysis of Storms Using GIS Track: Water Resources Author(s): Brian Hoblit, Steve Zelinka, Cris Castello, David Curtis Point data from rain gauges have been historically used to develop depth-area relationships, design storm sizes and depths, average storm vectors, etc. The results are often adversely influenced by the lack of data between the gauges resulting in design storms that do not reflect the true spatial structure of storms. In essence, point data were used to solve a spatial problem. OneRain calibrated sixty months of radar rainfall data over 100,000 sq. mi. centered over St. Louis, Missouri, and ingested those results into TITAN, a program developed at NCAR that identifies and analyzes individual storm cells every time step. For the sixty months, TITAN identified almost 900,000 individual storm cells. These results were ingested into ArcGIS to determine the design characteristics of storms over the St. Louis region. In essence, spatial data were used to solve a spatial problem.
