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 completed

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.

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
Cartography Tools
Engineering Tools
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 created
Project.xml saves your Project Settings
Help link, html popup

FMD Geodatabase FMD “Tree View” FMD Geodatabase in ArcCatalog

FMD Geodatabase
Once the .mdb is created, load layers through ArcCatalog or FMD
Metadata capabilities

Domain tables are within the FMD geodatabase, they correspond to FEMA compliant values.
Examples: units, line types
FMD–specific fields

FMD Geodatabase
Run Topology
FMD
ArcCatalog
Database QA/QC check with report generated
Clean field command
PLSS data attribution

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
24000 12000 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 t he 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
To access the project settings:
Right click on DFIRM: FMD_ County and select the project settings tab

Project Settings

Project Settings
Designed to allow the user
to modify the cartographic
symbols supplied with FMD
or allow the user to upload
their own symbols

Project Settings
Layer files used in map
production
FEMA compliant

Project Settings
Ability to
use own
Style files
Holds our
symbology

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

Project Settings
Special note module to easily place
any special or custom map note
Conforms to FEMA standards

Project Settings

Project Settings
Ability to use
own raster.lyr
file
If there are tiled
orthos, only
relevant tiles will
appear for each
panel

Spatial join to create dynamic legend from multiple files.

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
