Q3 is FEMA new digital flood insurance data products. It is seamless county-wide database. The final Q3 products will be available for both vector data, such as ArcInfo coverage, FEMA DLG, MapInfo format as well as Metadata, and raster data, such as canned panel maps later next year. This paper will discuss the Q3 data model, data capture and data conversion. It will focus on how to implement automation process using different programming technique for a large database design and data production line. It will also examine different mathematics and statistical models for checking and fixing both topological and attribute errors, such as one-node polygons, counting true vertex polygons, silver polygons as well as validity of attributes. Finally, it will discuss Q3 delivery format such as ArcInfo coverage, DLG file and MapInfo format-differences and solutions.
