DEVELOP AN AUTOMATION PROCEDURE FOR FEMA DIGITAL FLOODING INSURANCE DATA - Q3 PRODUCTS

(Programming for Data Process automation, Conversion, and QCQA)

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 formats as well as Metadata; and raster data, such as scanned panel maps. 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 some functions of mathematic and statistical models used for checking and fixing both topological and attribute errors, such as on-node polygon, counting true vertex for polygons, sliver polygons, multiple polygon labels as well as validity of attributes. Finally it will discuss Q3 delivery format, such as ArcInfo coverage, FEMA DLG file, and Map/Info files - differences and solutions.
