Nevada 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: Xing Liu, Geospatial Data Coordination Lead Regional Management Center IX (510) 879-0955 Xing.Liu@mapmodteam.com We appreciate the help of those who reviewed this document, in particular Ron Hess, GIS Supervisor Nevada Bureau of Mines and Geology University of Nevada, Reno M.S. 178 Reno, Nevada 89557-0088 775-784-6691 Ext. 46692 rhess@unr.edu Date Procedure discussed: March 5, 2007 Default Flood Hazard Base Map for the State The default base map for flood hazard maps for the State is recent, black/white, county-wide orthophotography data provided by local government to FEMA as public domain data. The resolution must be 1 meter resolution or better. If not available, locally provided vector basemap data or 2005 USDA National Agriculture Imagery Program (NAIP) imagery are used. 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: Preliminary 2005 USDA NAIP Imagery Data currentness: 2005 Accuracy/Scale: 1:12,000 Ground sample resolution: 1 meter Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: http://keck.library.unr.edu/data/naips/naips.htm Dataset contact: Ron Hess, rhess@unr.edu Notes: (1) The preliminary National Agriculture Image Program (NAIP) data files for the State of Nevada were provided through the courtesy of the Nevada State Mapping Advisory Committee. (2) 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) Transportation (roads, railroads, and airports) Dataset name: US Census Topologically Integrated Geographic Encoding and Referencing (TIGER)/Line files Data currentness: 2000 Accuracy/Scale: 1:100,000 Horizontal datum: NAD 83 Fee associated?

Data Distribution Process for State Data Primary access to state data is through the Virtual Clearinghouse for Nevada Geographic Information (http://www.nbmg.unr.edu/geoinfo/geoinfo.htm). 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 W.M.KECK Earth Sciences & Mining Research Information Center: http://keck.library.unr.edu/: The mission of the W. M. Keck Earth Sciences and Mining Research Information Center is to provide access for researchers, both on-site and from their remote desktops, to specialized bibliographic databases, scientific visualization and modeling packages, and geospatial data resources. This site provides access to download all USGS DOQ and DRG products for Nevada. Virtual Clearinghouse for Nevada Geographic Information: http://www.nbmg.unr.edu/geoinfo/geoinfo.htm: This Web site provides links to organizations that provide GIS data. At its meeting in January 1998 the State Mapping Advisory Committee agreed to establish this Web site as a beginning for a clearinghouse for geographic information. The Nevada Bureau of Mines and Geology manages the site. Southern Nevada GIS Data: http://gisgate.co.clark.nv.us/gismo/freedata.htm 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=NV Involving the State’s Geospatial Coordinator in Flood Studies The RMC has established initial contact with the NV NSGIC Representative to present an overview of FEMA’s Map Modernization Program. State Coordination Process for Building Geospatial Partnerships Nevada State Mapping Advisory Committee: http://www.nbmg.unr.edu/smac/smac.htm: The Governor of Nevada established the State Mapping Advisory Committee (SMAC) in 1983 to advise the U.S. Geological Survey (USGS) on state priorities for map products and to inform maps users about the status of mapping programs and the availability of map products. The Governor named the Director of the Nevada Bureau of Mines and Geology as the chair of SMAC. SMAC generally meets annually. The Federal Geographic Data Committee (FGDC), on November 6, 2000, formally recognized the Nevada State Mapping Advisory Committee as the Nevada Regional Cooperating Group in support of the National Spatial Data Infrastructure (NSDI) program. Nevada Geographic Information Society: http://www.ngis.org/portal/: The goals of the NGIS are: * To provide an objective educational forum without political, social, financial or national bias. * To foster the exchange of ideas and studies focused on the planning, operation, and consequences of such information systems. * To promote professional interaction, stimulate research, encourage publication, and generally aid the advancement of its members and other organizations having related objectives 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 state does not maintain a statewide GIS contacts list. Updates for contacts and local data sets may be coordinated/submitted through Ronald Hess: rhess@unr.edu Primary access to state resources and contacts are available through the Nevada State Mapping Advisory Committee Strong County GIS Departments exist in: * Clark County - http://www.co.clark.nv.us/ceit/gismo/gismo.htm * Washoe County - http://www.co.washoe.nv.us/gis/ 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).
