New Hampshire Purpose of the Procedure Flood insurance studies search for geospatial data during pre-scoping 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: Jeff Burm, Geospatial Data Coordination Lead Regional Management Center 1 (617) 482-4930 x4752 Jeff.Burm@mapmodteam.com We appreciate the help of those who reviewed this document, in particular Ken Gallager NH Office of Energy and Planning 57 Regional Dr. Concord, NH 03301 603.271.2155 ken.gallager@nh.gov Date Procedure discussed: February 21, 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). 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: “2003 National Agricultural Imagery Program (NAIP) Imagery Data currentness: 2003 Accuracy/Scale: Horizontal accuracy within +/- 3 meters of reference 1:12,000-scale digital ortho quarter quads. Ground sample resolution: 1 meter Horizontal datum: NAD 83 Fee associated? No charge when downloaded through the Internet. Available for redistribution? Yes Dataset source: Complex Systems Research Center, University of New Hampshire at http://www.granit.sr.unh.edu Dataset contact: GRANIT Database Manager, 603-862-1792, granit@unh.edu Notes: (1) 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. (2) For display in GIS software environments, it is recommended that users set the image stretch to "none" to achieve seamless coverage across multiple tiles within a county. The file format is MrSID, Generation 3. This image format is not supported in ArcView 3x. Users wishing to view the *.sid files in ArcView 3x may go to http://www.lizardtech.com/download/dl_download.php?detail=geo_avmrsid_dll&platfor m=win and follow the instructions provided (e.g. copy and unzip AVMrSID.dll to your Arcview32/bin directory, and invoke the MrSID extension as usual).

Yes Dataset source: Complex Systems Research Center, University of New Hampshire at http://www.granit.sr.unh.edu Dataset contact: GRANIT Database Manager, 603-862-1792, granit@unh.edu Notes: The development of this data layer was initiated in the early 1990's as a collaboration between the Society for the Protection of NH Forests (SPNHF), the NH Office of State Planning (OSP), and the Complex Systems Research Center at the University of New Hampshire (CSRC). While the methodologies used to develop the data set have evolved over a period of years, the basic approach has remained relatively constant throughout this period. As of 2001/2002, the entities responsible for the development of the data set include: OSP (collection, compilation, and automation of state/federal lands), the regional planning agencies (collection, compilation, and automation of municipally-managed parcels), SPNHF (collection and compilation of Forest Society Lands), and CSRC (collection, compilation, and automation of all other protected lands, and integration of all contributions into a seamless, statewide data set). The process starts with the collection of source information (PARCELSOURCE) from agencies protecting/managing parcels in the state. Protecting agencies typically include state/federal organizations, county/municipal agencies, land trusts, watershed associations, and other non-profit organizations. The protecting entity is asked to provide the best available source map, and the associated descriptive information, to the organization responsible for parcel compilation (SPNHF, OSP, an RPA, and/or CSRC). Extraterritorial jurisdiction (ETJ) boundaries Dataset name: NH Wildlife Actin Plan 2005: Coastal islands Data currentness: Publication Date: 20051001 Accuracy/Scale: Information not provided Horizontal datum: NAD 83 Fee associated? No Available for redistribution? Yes Dataset source: Complex Systems Research Center, University of New Hampshire at http://www.granit.sr.unh.edu Dataset contact: GRANIT Database Manager, 603-862-1792, granit@unh.edu Notes: New Hampshire does not indicate any ETJs; nevertheless this dataset would be as pertinent as if it were identified as such. The New Hampshire Fish and Game Department (NHFGD) has worked together with partners in the conservation community to create the state's first Wildlife Action Plan (WAP). The plan, which was mandated and funded by the federal government through the State Wildlife Grants program, provides New Hampshire decision-makers with important tools for restoring and maintaining critical habitats and populations of the state's species of conservation and management concern. It is a pro- active effort to define and implement a strategy that will help keep species off of rare species lists. For more information about the NH Wildlife Action Plan, please see the files wapexecsummary.pdf and wapplannershandout.pdf. Development of this coverage provides general coastal island locations within the state of New Hampshire. Terrain (elevation) Dataset name: Digital Elevation Model Data currentness: 19790701 to present Accuracy/Scale: 7 meter RMSE or better; the header record provides the accuracy measured. Vertical datum: Not Provided Fee associated? No charge when downloaded from the internet. Cost of reproduction for provision on CD/ROM or other media. Available for redistribution? Yes Dataset source: Complex Systems Research Center, University of New Hampshire at http://www.granit.sr.unh.edu Dataset contact: GRANIT Database Manager, 603-862-1792, granit@unh.edu Notes: USGS elevation data that have been reprocessed and are distributed by the State. Data Distribution Process for State Data Downloadable electronic data is available for download from GRANIT’s website at http://www.granit.sr.unh.edu/cgi-bin/load_file?PATH=/data Ordering instructions for data provided on media: Email GRANIT (granit@unh.edu) or order from web site at http://www.granit.sr.unh.edu. The turnaround is two weeks. Digital data in NH GRANIT represent the efforts of the contributing agencies to record information from the cited source materials. Complex Systems Research Center, under contract to the NH Office of State Planning, and in consultation with cooperating agencies, maintains a continuing program to identify and correct errors in these data. OSP, CSRC, and the cooperating agencies make no claim as to the validity or reliability or to any implied uses of these data. Federal Nationwide Geospatial Data Holdings Information about nationwide holdings and programs of Federal agencies is available from the Mapping Information Platform web site at https://hazards.fema.gov/femaportal/docs/ProgFacts.pdf. 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 New Hampshire Geographic Information System (NH GRANIT) is a cooperative project to create, maintain and make available a statewide digital geographic data base serving information to state, regional and local government decision-makers. The NH GRANIT Data User Guide is available at http://www.granit.sr.unh.edu/cgi- bin/load_file?PATH=/data/userguide.html. Section I of this Users Guide provides an overview of NH GRANIT (Geographically Referenced Analysis and Information Transfer), including its objectives, participating agencies, organization, and general characteristics. Section II presents standards governing the creation and updating of the data base layers. Section III presents the procedures for obtaining access to NH GRANIT data. A companion document, NH GRANIT Data Catalog, describes each of the available digital data layers and its status. 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=NH. Of special interest are: New Hampshire Office of Energy and Planning (NH OEP) – The GIS program of NH- OEP has two main functions. First, the program provides mapping support and geographic analysis to other programs in the office. Second, the program develops particular geographic data layers for the statewide GRANIT project and provides guidance to GRANIT through its position as coordinator of the statewide GIS Advisory Committee. See http://nh.gov/oep/programs/GIS/index.htm for more information. New Hampshire Geographically Referenced Analysis and Information Transfer System (NH GRANIT) – GRANIT is a cooperative project to create, maintain, and make available a statewide geographic data base serving the information needs of state, regional, and local decision-makers. The core GRANIT system includes a geographic database, hardware and software to build, manage, and access the database, and a staff of experts knowledgeable in geographic information systems, image processing, and computer analysis. In addition to database development and maintenance, the GRANIT staff offers a range of application development, training, and related technical services to GIS users in the state and the region. See http://http://www.granit.sr.unh.edu for more information. USGS New England Mapping Partnership Office – The USGS partnership program is the geospatial liason between the USGS and the New England States. The office is responsible for New Hampshire and other New England states. Involving the State’s Geospatial Coordinator in Flood Studies In order to participate in the FEMA flood hazard mapping effort, this office prefers to be contacted in all of the following ways: a. Send project list at the start of each year New Hampshire’s Geospatial Coordinator already has a working relationship with the office (GRANIT), a cooperating technical partner (CTP), that is responsible for updating many of the multi-hazard maps, and they have access to their state’s flood map modernization business plan. GRANIT is also the repository for the DFIRMs, which can be downloaded from their website. The RMC is in regular contact with them to discuss any issues related to Map Modernization.. State Coordination Process for Building Geospatial Partnerships The NH GIS Advisory Committee was established in 1987 as a sub-committee of the Governor's Council on Resources and Economic Development (CORD). The Committee was formed to coordinate mapping and GIS-related activities of the members, and to recommend policies, standards, and related measures to CORD for endorsement and implementation. The Committee meets regularly, and has drawn into its membership representatives of all state agencies actively involved in mapping, as well as representatives of several federal agencies, regional planning agencies, and the University of New Hampshire.
