Geospatial Data Coordination The Power of Metadata

• Jeff Tornatore, Michael Baker Jr., Inc.

2
Importance of Coordination

• Map Mod will be collecting detailed mapping data
  nationwide
• The U.S. has national goals to share mapping data
• Reduce overall cost by reusing good local data
• Maximize local input into maps

3
MIP Vision

• Capture and document all data used by Map Mod
• Not just the finished flood data
• Same goal as the TSDN, just digitally managed

4
Federal Policy

• Circular No. A-16, Coordination of Geographic
  Information and Related Spatial Data Activities
• Requires coordination and
• cooperation across Federal Agencies
• Section 2.b.2, All spatial data collected or
  derived directly or indirectly using federal
  funds will have FGDC metadata.
• Section 6.b, As examples, this Circular applies
  to, but is not limited to FEMAs Flood Plain
  Mapping program and other federal activities that
  involve national surveying, mapping, remote
  sensing, spatially referenced statistical data,
  and Global Positioning System (GPS).

Geospatial Data Coordination Policy

• FEMA Geospatial Data Coordination Policy signed
  in August 2005
• Establishes the principles for coordinating,
  communicating, documenting, and reporting
  existing and proposed geospatial data collected,
  produced, or manipulated under FEMAs Map
  Modernization  
• Enables data sharing and secondary data use

Geospatial Data Coordination Guidance

• FEMA Geospatial Data Coordination Implementation
  Guide distributed to mapping partners in Spring
  of 2005
• Supports the goals of the Policy
• Provides direction to mapping partners on
  geospatial data discovery and documentation
• Directs partners to first check with the State
  and locals for data before checking Federal
  sources
• Requires documentation for any State or local
  terrain or imagery expected to be used for a FEMA
  project in the NDEP/NDOP Project Tracker

Tools for Partners

• Standard Operating Procedures for each State
• Fact sheets on all major Federal programs
• List of Federal contacts by State
• Listserve for Map Mod geospatial issues
• NDOP and NDEP tracking systems

Mapping Information Platform (MIP)

• FEMAs MIP is a Web-based technology that enables
  the manage-ment, production, extraction, and
  sharing of FEMA's Map Modernization data.
• Metadata accompanies data submittals to the MIP.

10
FEMA Requirements

• The MIP Workflow requires the mapping partner to
  submit all intermediate data sets for a project
  at defined intervals along the life cycle of a
  DFIRM.
• Metadata is used to register each data
  deliverable with the Mapping Information Platform
  (MIP).
• This occurs after the deliverable has passed
  Quality Assurance steps.
• Registration with the MIP allows for subsequent
  discovery and download of the deliverable via the
  Search and Retrieve tool in the MIP.

11
What is Metadata?

• The documentation FEMA needs to show that work
  done is of appropriate quality
• The catalog information FEMA needs to archive and
  find the data
• The Federal Geographic Data Committee (FGDC)
  metadata definition
• A metadata record is a file of information,
  usually presented as an XML document, which
  captures the basic characteristics of a data or
  information resource. It represents the who,
  what, when, where, why and how of the resource.
• http//www.fgdc.gov/metadata

12
Collecting and Publishing Metadata

• Key purposes for collecting and publishing
  metadata
• Maintain an organizations internal investment in
  geospatial data
• Provide information about an organizations data
  holdings to data catalogs, clearinghouses, and
  brokerages
• Provide information needed to process and
  interpret data to be received by transfer from an
  external source

13
Metadata Profiles

• FEMA Metadata Profiles distributed to RMCs and
  mapping partners in January of 2006
• FGDC compliant metadata records are required for
  every data deliverable.
• There is a profile for each data deliverable
  type.
• The FEMA profile defines required elements and
  element domains.
• Profiles ensure that metadata elements necessary
  for queries to discover the data submissions are
  populated correctly.
• Tools are being developed and released for
  metadata creation and validation.
• https//hazards.fema.gov Tools and Links tab

14
Metadata Tools

• DFIRM Metadata Builder
• Metadata .txt creation
• Profile compliant

• Metadata Manager
• .txt to .XML conversion
• Profile validation

15
MIP Components

• Based on metadata elements, the MIP components
  Content Manager and Map Viewer are dedicated to
  cataloging, querying, and retrieving data.
• Content Manager is a database catalog of the
  information stored on the MIP.
• Search and Retrieve is a MIP tool for data
  discovery and download.
• Map Viewer is an interactive map available to the
  public for viewing MIP data.

16
Content Manager Archiving Data

• Users upload data submissions with metadata.
• Data is archived for all spatial submissions
  based on the metadata profiles.
• Data is archived for all non-spatial submissions
  (e.g., Scoping meeting minutes) based on key
  metadata elements These would not be not
  complete FGDC-compliant metadata files. Elements
  include
• Placekeys
• Title
• Abstract
• Access Restriction
• Effective Date

17
Search and Retrieve

• Provides for spatial and tabular searches of
  FEMAs data holdings
• Provides access to full metadata record for each
  submission
• Provides for download of all unrestricted data
  deliverables
• Available to authenticated MIP users only
• Allows for download of common data types in a
  consistent format and structure as per Appendix L
  and N standards

Search and Retrieve
General search for spatial and non-spatial data
submissions for Lonoke County
Discovered data submissions for Lonoke County
19
Search and Retrieve
Access the individual data submission via the
provided link.
Excerpt from metadata file Headings drive the
location searches Searched for Lonoke in the
County search
Excerpt of data files in the uploaded data
submission
20
Search and Retrieve
Coordinates auto-populate in the query based on
the map extent in Map Viewer.
The query returns specific data type submissions
in which the bounding coordinates in the metadata
file are located within the queried extent.
21
Search and Retrieve
Access_Constraints None
If the metadata file declares no access
constraints, then all data files in the
submission can be downloaded.
If the metadata file declares any access
constraints, then none of data files in the
submission can be downloaded. .
Access_Constraints Restricted
22
Map Viewer Components

• Geocoder Allows a user to search for an
  address, coordinate, saved location, or community
• Map Legend Allows a user to create a map with
  selected data layers (flood data, hazards,
  imagery, basemap layers) and to access metadata
• Map Viewer Allows a user to navigate the map,
  save the view, print the screen to a PDF, and
  automatically display DFIRM layers only

23
Map Viewer Metadata

• The Map Viewer will return all available metadata
  records for the extent of the map window when a
  data layer is clicked in the legend.

24
MIP Metadata Published

• MIP metadata published as web service compliant
  with Open Geospatial Consortium Catalog Service
  (CSW).

Geospatial One-Stop

• Metadata is harvested by Geospatial One-Stop
  (GOS)
• GOS integrates geospatial data catalogs
  nationwide. The goal is to provide a one-stop
  locations where any user can find geospatial data

• Will provide the public with ability to discover
  FEMAs data holdings
• Helps FEMA meet requirements from OMB Circular
  A-16

Summary

• Metadata, in conjunction with FEMAs Mapping
  Information Platform (MIP), enables the
  management, production, extraction, and sharing
  of FEMA's Map Modernization data.
• Content Manager allows discovery of and access to
  data.
• Map Viewer displays spatial data and provides a
  link to metadata.
• The MIP shares metadata with GOS to facilitate
  data sharing with the widest possible audience.
