Introduction Map Modernization Project:
Administered by FEMA through the National Flood Insurance Program (NFIP)
Upgrade floodplain maps by creating and distributing them in a GIS format
In the past, maps were produced by FEMA and distributed on paper
All told, 47 of the state’s most populous counties will have new Digital Flood Insurance Rate Maps (DFIRMS) when this project is (DFIRMS) when this project is completedcompleted
Introduction Mapping Information Platform (MIP):
FEMA’s online application tool: Great for project management
Handy for remote access since desktop ArcGIS is not needed
However, because it is run from FEMA’s server with numerous users Nationwide, it is very SLOW.
DFIRM
Introduction Flood Map Desktop(TM) (FMD) is a free
public domain software developed by the company PBS&J
FMD manages your work and remembers your project settings
FMD will also create data such as graticules and masking on-the-fly
Introduction FMD Overview
1. Cartography Tools2. Engineering Tools3. Data Management Tools
Geodatabase Formation
Flood Mapping Tab
Create/choose your Workspace
Create your Project
Geodatabase & xml created
.elm File Stores labels and leaders Graphic elements file, .elm, generated
the first time you create labels in a project.
An access database that stores the graphics elements on a panel by panel basis.
A simplified annotation feature class that FMD manages for the DFIRM projects.
Each project has its own .elm
Geodatabase Formation
Geodatabase created
Project.xml saves your Project Settings

Once the .mdb is created, load layers through ArcCatalog or FMD
Metadata capabilities
Geodatabase Formation
Domain tables are within the FMD geodatabase, they correspond to FEMA compliant values.
• Examples: units, line types FMD–specific fields

Geodatabase Formation
Base Index Spatial boundary of the aerial DOP used as base
map.
FMD Geodatabase The Quad
Index is created through FMD.
• Based on USGS quadrangles
• Created when the FIRM Panel Index is made
FMD Geodatabase – FIRM Panel Index
Created through FMD based on the Quad Index.
Panel scale determined by FEMA rules
2400012000
6000
FMD Geodatabase Start with 24000-scale quads, manually
split the areas as necessary using the FMD “Panel Toolbar”
Select panel, then push the button Once saved, push Renumber
Project Settings The Project Settings display is used to set up the
template of the map panel. These settings include:
Specifying tSpecifying the type of symbology to use The notes to users displayed on the maps, title block, and legend A project.xml is created that sets global settings for entire project; reloads each time
Project settings can be changed at any time in production

Project Settings Pin-to-Graphics option for adding additional text when necessary for individual projects
Project Settings
Pin-to-Graphics: able to delete from folder when no longer needed or use in other projects

Final Deliverables
PDFs of maps PNGs of maps, as well as PGWs
(georeferenced)
Final Deliverables
Political Areas Political Lines Flood Hazard Areas Flood Hazard Lines Base Flood Elevation
Lines Cross-Section Lines Benchmarks General Structures River Marks (if
present) PLSS Areas PLSS Lines Water Area
Water Lines Transportation Lines Base Index Quadrangle Index Label Points Label Leaders FIRM Panel Index Tables (dbf, not
shp): Study Info Community Info Cross-Section
Station Start Metadata (xml & txt)
• DFIRM layers need to be submitted to FEMA in shp, mif, and e00 format. Metadata in xml and txt.
Final Deliverables Label Leader and Label Point layers need to be
uploaded from the elm into the geodatabase.
Final Deliverables
FMD exports FEMA-compliant layers Strips FMD-only fields
Conclusion FMD has made the DNR MapMod team
four times more efficient. Map making/cartography Data creation Data management
FMD helps with data standardization and storage
Responsive help from PBS&J No outages to contend with
No internet connection is required
