Idaho 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: Oren Gruber, Geospatial Data Coordination Lead Regional Management Center X 206-344-3897 / 206-553-9794 Oren.Gruber@mapmodteam.com We appreciate the help of those who reviewed this document, in particular Nathan Bently, Idaho GIS Coordinator ITRMC Staff (208) 332-1879 nbentley@adm.idaho.gov Date Procedure discussed: 2/2/2007 Scott van Hoff, Geospatial Liaison for Idaho U.S. Geological Survey 208-387-1351 svanhoff@usgs.gov Date comments received: April 2007 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), one-meter NAIP imagery from 2004 and 2006. 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. Major State Holdings Orthophotos Dataset name: 1-meter Digital Orthoimages (identified as “NAIP” and “Surdex”) Data currentness: 2004 and 2006 respectively Accuracy/Scale: 1:12,000-scale Ground sample resolution: 1-meter Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: Inside Idaho Geospatial Data at http://www.insideidaho.org Dataset contact: Nathan Bently, ITRMC Staff, (208) 332-1879, nbentley@adm.idaho.gov Notes: (1) Not statewide, partial coverage of Northern panhandle, agricultural areas, and all major urban areas. (2) The 2004 data are from from the National Agriculture Imagery Program (NAIP). NAIP imagery has many uses, and many states participate in NAIP. NAIP is leaf-on imagery and is not cloud-free, and so the ground might be obscured. So, while NAIP (and other such imagery) can be used as a base maps, the imagery must be checked to ensure that it provides a clear view of important features on the ground for areas of significance for flooding (see Appendix C of the Geospatial Data Coordination Implementation Guide for more discussion). Also see the “Federal Mapping Program Factsheets” available through “Tools & Links” on the MIP web site.

Data Distribution Process for State Data The Idaho Geospatial Committee (IGC), in April 2002, recognized INSIDE Idaho (http://www.insideidaho.org) as the clearinghouse for computerized geographic information for the state. INSIDE Idaho serves as the mechanism to share data, resources, technologies, and expertise to meet the increasing demands for Idaho’s geospatial information by educational institutions, government and business professionals, as well as Idaho citizens. Federal Nationwide Geospatial Data Holdings Information about nationwide holdings and programs of Federal agencies is available from the Mapping Information Platform web site at . Finding and Accessing Other Existing Geospatial Data Find below information about and links to ways of searching for additional geospatial data available for the State. These capabilities can be useful for finding geospatial data other than the statewide and Federal data listed above, including those of special governments, counties and parishes, municipalities, tribes, universities, and other organizations. Clearinghouses and Inventories for the State The Idaho Geospatial Committee (IGC), in April 2002, recognized INSIDE Idaho (http://www.insideidaho.org) as the clearinghouse for computerized geographic information for the state. INSIDE Idaho serves as the mechanism to share data, resources, technologies, and expertise to meet the increasing demands for Idaho’s geospatial information by educational institutions, government and business professionals, as well as Idaho citizens. National Digital Orthophoto Program (NDOP) and National Digital Elevation Program (NDEP) Tracking Systems These systems allow the search of orthophoto and elevation project information entered by federal and other organizations. To access the NDOP system, go to the NDOP web site at and follow the link “Project Tracking.” For the NDEP system, go to the NDEP web site at and follow the link “Project Tracking.” TED Query Tool This tool provides access to information about Federal, state, and local government agency and private sector data holdings gathered by the Census Bureau. It is available through the geospatial data coordination lead at the Regional Management Center. 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 https://hazards.fema.gov/contacts/statecontacts/contacts.asp?page=ID Additional useful contacts for the State can be found at http://www2.state.id.us/itrmc/committees.htm#igc. Involving the State’s Geospatial Coordinator in Flood Studies Participation should be focused at the local level of government. If a local government feels it is getting a return on its effort and investment, they will participate in data coordination. The extent to which an SDI (Spatial Data Inventory) works depends largely on County Commissioners, who are usually unfamiliar with specific GIS concerns, but the participation of such personnel can be greatly influenced by the impact on “security” and “emergency planning” issues. State Coordination Process for Building Geospatial Partnerships The Idaho Geospatial Committee (see http://www2.state.id.us/itrmc/committees.htm#igc) provides policy-level direction and promotes efficient and effective use of resources for matters related to geographic information. 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 . Additional useful contacts for local government can be found at http://www2.state.id.us/itrmc/committees.htm#igc.
