Illinois Purpose of the Procedure Flood insurance studies search for geospatial data during prescoping and scoping tasks. If needed data are not available, studies might fund the collection of new data and would like to know about other organizations that might share in these costs. Detailed information about the role geospatial data coordination plays in studies is in the Geospatial Data Coordination Implementation Guide, which is available at , and in Scoping Guidelines: Pre-scoping and the Scoping Meeting, which is available through the Regional Management Center (RMC). Resources developed through FEMA’s geospatial data coordination activities provide information about data and contacts for organizations that have geospatial data that cover large areas (like states) in which many studies are interested. Studies can avoid wasting time with dead-end searches and cold calls by starting with these proven sources of information. One resource is this Geospatial Data Coordination Procedure. It outlines sources of geospatial data and contact information, preferences for base map data and state geospatial participation in studies, and other useful information for the State. If you have questions about this procedure or other geospatial data coordination resources, contact the geospatial data coordination lead in your Regional Management Center: Hans A. Anderson, Geospatial Data Coordination Lead Regional Management Center 5 (312) 575-3927 hans.anderson@mapmodteam.com We appreciate the help of those who reviewed this document, in particular Name Organization Phone Email Date Procedure discussed: Default Flood Hazard Base Map for the State The default base map for flood hazard maps for the State is an image base map (orthophoto). Geospatial Data Coverage Find below information about and links to statewide (and Federal agencies’ national) geospatial datasets. The list is provided to save time during pre-scoping and scoping activities when building a list of candidate geospatial datasets available for the study; it is not a prescription of datasets that must be used in a flood insurance study.

Geospatial One-Stop Geospatial One-Stop, available at , provides access to geospatial data from many sources. Two parts of the site that should be investigated are the “data categories” for existing data and the “marketplace” for data that are planned or in-work and for potential partners for new data collection activities. Working with People Useful State and Federal Contacts The main contacts for the State’s geospatial activities and Federal agencies’ representatives in State are available on the Mapping Information Platform web site at Involving the State’s Geospatial Coordinator in Flood Studies The state geospatial coordinator prefers to be contacted to participate in the FEMA flood hazard mapping effort.

State Coordination Process for Building Geospatial Partnerships The Illinois GIS Council (CGC), at http://www.illinois.gov/ilgic/, is made up of representatives from local, tribal, state, and federal government agencies and the private sector, and collaborates on the planning, implementation, and maintenance of an Illinois GIS infrastructure. The term infrastructure is used to encompass systems, organizational programs, policy, standards, procedures, and any other factors that affect the ability of member organizations to jointly develop or acquire, share, and maintain spatial data adequate to their needs. A key element of the CGC is the formation and participation of local collaborative (e.g. Regional GIS Councils). Composed of representatives of county, city, and tribal governments, resource conservation and other special districts, private and public utilities, local colleges and universities, and private sector organizations, these regional collaborative are essential to council success. Finding Local Geospatial Contacts Local contacts, including those from special government districts (for example, a regional planning commission); counties, parishes, or equivalent governments; tribes, municipal governments; and other organizations (for example, local universities) also have geospatial data that can help a flood insurance study. Contact information is available from the FEMA archive and web searches at government link portals such as . The Illinois GIS Association at http://www.ilgisa.org, has a membership list which includes many county and municipal representatives. The contact is Sherrie Taylor at taylor@niu.edu; Regional Development Institute, Northern Illinois University, DeKalb, IL 60115; phone: (815) 753-0925. Provide Feedback on This Procedure When you find information in this Procedure or in other FEMA or State resources that are outdated, please tell the geospatial data coordination lead in the Regional Management Center what was wrong and the correct information (if you know it).
