Floodmap Desktop for ArcGIS


Published on

The Wisconsin Department of Natural Resources directly
produces the state’s Digital Flood Insurance Rate Maps
(DFIRMs) under FEMA’s Map Modernization Program. This
presentation will discuss how we use an ArcMap 9.2 extension,
Flood Map Desktop 9™ (FMD), to create FEMA-compliant
DFIRM data, metadata, and map deliverables. The FMD tool
has greatly improved our program’s work flow and efficiency.
As we demonstrate the FMD structure and FMD toolbars, we
will discuss geodatabase creation and management, topology,
domain tables, formatting style files, symbology, label creation
and storage, data exporting, and project settings which form the
base templates for our maps.
