If needed data are not available, studies might fund the collection of new data and, where applicable, encourage cost sharing among existing organizations. Detailed information about the role geospatial data coordination plays in studies is in the Geospatial Data Coordination Implementation Guide, which is available at https://hazards.fema.gov/femaportal/docs/GeoDataImplem_V3.pdf, and in Scoping Guidelines: Pre-scoping and the Scoping Meeting, which is available through the Regional Support Center (RSC). 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. Dead-end searches and cold calls can be avoided 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 RSC: Xing Liu, Geospatial Data Coordination Lead Regional Service Center IX (510) 879-0955 xliu@mbakercorp.com Default Flood Hazard Base Map for the State The default base map for flood hazard maps for the State is recent, black and white, countywide orthophotography data provided by local governments to FEMA as public domain data. The resolution must be 1-meter resolution or better. If not available, locally provided vector basemap data or 2006 USDA National Agriculture Imagery Program (NAIP) imagery are used. Geospatial Data Coverage Below, you will find links to statewide (and Federal agencies’ national) geospatial datasets and information about them. The list is provided to save time when building a list of candidate geospatial datasets available for the study during discovery activities; it is not a prescription of datasets that must be used in a Flood Insurance Study. Major State Holdings Orthophotos Dataset name: 2010 USDA NAIP Imagery Data currentness: (NAIP 2011 not flown for NV) 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/NAIP Dataset contact: Zachary Newell, newellz2@unr.edu Notes: Members of the Nevada State Mapping Advisory Committee have funded NAIP 2010 for Nevada. NAIP imagery has many uses, and many States participate in NAIP. NAIP is leaf-on imagery and is not cloud-free, so the ground might be obscured. While NAIP (and other such imagery) can be used as 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. Transportation (roads, railroads, and airports) Dataset name: US Census Topologically Integrated Geographic Encoding and Referencing (TIGER)/Line files Data currentness: 2010 Accuracy/Scale: 1:100K Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Are road names part of the dataset? Yes Dataset source: http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html Dataset contact: http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html and http://www.nd.gov/gis/mapsdata/data/extractdata/ Notes: The US Census is in the process of realigning TIGER/Line files to improve positional accuracy. New data are published every six months. Hydrography (rivers, streams, lakes, and shorelines) Dataset name: USGS-maintained National Hydrography Data set (NHD) for NV Data currentness: 2010 Accuracy/Scale: 1:24K Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Are hydrography names part of the dataset? Yes Dataset source: http://nhd.usgs.gov/ Dataset contact: http://nhd.usgs.gov/ and http://www.nd.gov/gis/mapsdata/data/extractdata/ Notes: N/A Political boundaries (county, municipal) Dataset name: US Census Topologically Integrated Geographic Encoding and Referencing (TIGER)/Line files (Designated Places) Data currentness: 2010 Accuracy/Scale: 1:100K Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html Dataset contact: geo.tiger@census.gov Notes: N/A Publicly owned lands (national, State, and local parks, forests, etc) Dataset name: Surface Land Ownership from Nevada Bureau of Land Management Data currentness: 2010 Accuracy/Scale: 1:100K Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: http://www.nv.blm.gov/gis/geospatial_data.htm Dataset contact: N/A Notes: This dataset was created to display the management status of the land through the State of Nevada. It has been updated to reflect the most current GCDB lines from Premier data. The ownership for each smallest division was identified by the previous land status layer. In areas of confusion or pieces that were divided in areas smaller than GCBD, the MTP was referenced as the final authoritative sourcee. Public land survey system (PLSS) (township and section lines) Dataset name: PLSS from Nevada Bureau of Land Management Data currentness: 2007 Accuracy/Scale: 1:100K Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: http://www.nv.blm.gov/gis/geospatial_data.htm Dataset contact: N/A Notes: This layer was developed by the US Bureau of Mines (USBM), Western Field Operations Center, through digitizing and joining all 100,000 BLM surface management maps of Nevada in 1988 through1990. The original publication for which the data were created was by W.D. Crandell and M.M. Hamilton, entitled “Availability of Federally Owned Minerals for Exploration and Development in Western States: Nevada, 1985;” USBM Special Publication, 1990, 54 pp. The data were used by the USBM to create mine claim density maps. USGS publications OFR99-540 utilized the data in creating a specific mine claim density map of Nevada with 1996 claim data. Cadastral (parcels) No coverage available. Notes: Parcel data is available in Washoe and Clark counties. Very limited parcel data is available outside of these counties. Extraterritorial jurisdiction (ETJ) boundaries No coverage available. Terrain (elevation) Dataset name: USGS DEM Data currentness: Varies Accuracy/Scale: 1:24K for most of the State Vertical datum: NGVD 29 Fee associated? No Available for redistribution? Yes Dataset source: http://ned.usgs.gov/ Dataset contact: N/A Notes: As of 2004, the State converted DEMS from 30 meters to 10 meters for the entire State. This data is available through the USGS NED site. Useful Risk MAP Discovery Data Sources Preliminary information on Discovery data sources is provided in this document to reduce the level of effort needed on each subsequent Discovery data collection effort. Coordination with local community sponsors for additional local data still remains an integral part of Discovery and local data should be used where appropriate. The National Geospatial Data Coordination Procedure document contains information on data resources available from other Federal agencies (OFAs), including those that FEMA maintains at the national level, and should be used in conjunction with this State Geospatial Data Coordination Procedure document. In addition, FEMA and its contractors have created a geospatial Discovery Data Repository to host data that are not readily accessible through direct sources such as Web sites or subscription services and/or are not updated on a frequent basis. Instructions for accessing the Discovery Data Repository are provided in the National Geospatial Data Coordination Procedure document. Instructions for accessing the Discovery Data Repository are provided in the National Geospatial Data Coordination Procedure document. Table 1 identifies data resources that are available at the regional and State levels, and also if there are no data available other than the national datasets. Resources in this table have been identified as appropriate for Discovery projects and may not represent the best data sources for FIRM production (please see the Preferred Base Map Sources section of this document for geospatial data that meets FIRM production requirements).

Federal Nationwide Geospatial Data Holdings Information about nationwide holdings and of Federal agencies’ programs is available from the Mapping Information Platform website at https://hazards.fema.gov/femaportal/docs/ProgFacts.pdf. Finding and Accessing Other Existing Geospatial Data Below, you will find 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. 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 onsite 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. Nevada Bureau of Land Management Geospatial Data Portal http://www.blm.gov/nv/st/en/prog/more_programs/geographic_sciences/gis/geospatial_data.html This website provides links to organizations that provide GIS data. BLM Nevada collects geospatial data using a variety of methods including GPS, on-screen digitizing, and conversion of tabular data and legal descriptions. Data from other Federal, State, and local agencies are also used when available. 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. The NDOP system can be accessed at http://www.ndop.gov, and follow the link “Project Tracking.” The NDEP system can be accessed at http://www.ndep.gov, and follow the link “Project Tracking.” Geospatial One-Stop Geospatial One-Stop, available at http://www.geodata.gov/, 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-progress 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 the State are available on the Mapping Information Platform website at https://hazards.fema.gov/contacts/statecontacts/contacts.asp?page=NV Involving State’s Geospatial Coordinator in Flood Studies The RSC has established periodic communications with the Nevada NSGIC representative. 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. On November 6, 2000, the Federal Geographic Data Committee formally recognized the Nevada State Mapping Advisory Committee as the Nevada Regional Cooperating Group in support of the National Spatial Data Infrastructure 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. F inding 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 archives and government link portals such as http://www.statelocalgov.net. The State does not maintain a statewide GIS contacts list. Updates for contacts and local datasets may be coordinated/submitted through Jennifer Mauldin, mauldin@unr.edu. Primary access to State resources and contacts are avaialble through the Nevada State Mapping Advisory Committee. Strong County GIS Departments exist in: .
