Abstract

Geographic Information Systems (GIS) technology combines mapping software with database management tools to collect, organize, and share many types of information. This presentation will provide the audience with an introduction to GIS and how it can be used to aid in the management of floodplain and stormwater data and infrastructure. Within a GIS, geographical information is stored in a database that can be queried and graphically displayed for analysis. By overlaying or intersecting different geographical layers, floodprone areas can be identified and targeted for mitigation or stricter floodplain management practices. Example applications that will be illustrated include: mapping stormwater infrastructure; and calculating the percentage of land in the floodplain.

Abstract

GIS projects require the integration of a number of disciplines in order to be successful. These disciplines may include data conversion, database design, graphic representation (map creation), software manipulation and software deployment. This presentation will demonstrate how to bring all of these aspects together to insure that any efforts you undertake when building or improving a stormwater system layer will be more efficient and cost effective and help you reach your goal in a timely manner. We will further discuss the value and uses of this data and the ability to use it to better manage your stormwater quantity and quality programs.
