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

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

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

(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
