洪水淹没数据在受影响社区和（或）地区的地图中呈现时对决策者最有用。但由于数据稀少，很少涵盖洪水的全部范围，因此需要对信息进行内插和外推。许多地理信息系统提供了各种插值工具，但这些工具往往忽略了影响洪水的地形和水力特征的影响。为了改进飓风丽塔产生的风暴潮图，开发了一种障碍物制图方法。2005年9月24日午夜（00：00）至中午（12：00），每隔3小时绘制一次最大风暴潮地图。改进后的地图描绘了风暴潮高程和洪水范围。将改进后的最大风暴潮图中的风暴潮淹没范围与联邦紧急事务管理局（FEMA）编制的地图中的洪水淹没范围进行了比较。这两幅地图的边界大体上比较得很好，特别是沿着沿着卡尔卡休河。此外，还根据最大风暴潮图绘制了与路易斯安那州海岸平行的横截面剖面图，其中包括FEMA高水位线。
Flood‐inundation data are most useful for decision makers when presented in the context of maps of affected communities and (or) areas. But because the data are scarce and rarely cover the full extent of the flooding, interpolation and extrapolation of the information are needed. Many geographic information systems provide various interpolation tools, but these tools often ignore the effects of the topographic and hydraulic features that influence flooding. A barrier mapping method was developed to improve maps of storm tide produced by Hurricane Rita. Maps were developed for the maximum storm tide and at 3‐h intervals from midnight (00:00 hours) through noon (12:00 hours) on 24 September 2005. The improved maps depict storm‐tide elevations and the extent of flooding. The extent of storm‐tide inundation from the improved maximum storm‐tide map was compared with the extent of flood inundation from a map prepared by the Federal Emergency Management Agency (FEMA). The boundaries from these two maps generally compared quite well especially along the Calcasieu River. Also a cross‐section profile that parallels the Louisiana coast was developed from the maximum storm‐tide map and included FEMA high‐water marks.
