This data set contains 13 categories of land use data (polygons) for Rockingham County, New Hampshire. The primary data used to derive the layer were 1998 United States Geological Survey (USGS) 1:12,000-scale, black & white, Digital Orthophoto Quadrangles (DOQs). Other sources used to develop the classification included road centerline data from the New Hampshire Department of Transportation (NHDOT) and USGS Digital Line Graphs (DLGs), surface water data from the Federal Emergency Management Agency Digital Flood Insurance Rate Maps (DFIRMs), wetlands data from the National Wetlands Inventory (NWI) of the United States Fish and Wildlife Service (FWS), and Landsat Thematic Mapper imagery.

This file, along with two others of overlay districts, were created to produce a new, official zoning map series in 2009 for the Town of Rockingham and Village of Bellows Falls, Vermont. The zoning bylaw was last amended on November 5, 2019, and these boundaries are current to that amendment. The three files are originally named Zoning09_poly (town-wide zoning districts), Zoning09_NatRes (Natural Resource overlay district), and Zoning09_Design (Design Control overlay district in the Village of Bellows Falls). These shapefiles exist for distribution; the master zoning data are stored in a Geodatabase. The master Geodatabase file contains line attributes specifying the type of zoning district boundary. These files are based upon the Town of Rockingham Zoning Bylaws and several existing zoning maps. Where appropriate, zoning district boundaries were identified as coinciding with existing ground features such as roads, right-of-way boundaries, surface waters, railroads, or parcels, as setbacks from these features, or as lines connecting corners or intersections of these features.

North Carolina Effective Flood zones: In 2000, the Federal Emergency Management Agency (FEMA) designated North Carolina a Cooperating Technical Partner State, formalizing an agreement between FEMA and the State to modernize flood maps. This partnership resulted in creation of the North Carolina Floodplain Mapping Program (NCFMP). As a CTS, the State assumed primary ownership and responsibility of the Flood Insurance Rate Maps (FIRMs) for all North Carolina communities as part of the National Flood Insurance Program (NFIP). This project includes conducting flood hazard analyses and producing updated, Digital Flood Insurance Rate Maps (DFIRMs). Floodplain management is a process that aims to achieve reduced losses due to flooding. It takes on many forms, but is realized through a series of federal, state, and local programs and regulations, in concert with industry practice, to identify flood risk, implement methods to protect man-made development from flooding, and protect the natural and beneficial functions of floodplains. FIRMs are the primary tool for state and local governments to mitigate areas of flooding. Individual county databases can be downloaded from https://fris.nc.gov Updated Jan 17th, 2025.

NOTE: DO NOT DOWNLOAD THE IMAGERY BY USING THE MAP OR DOWNLOAD TOOLS ON THIS ARCGIS HUB ITEM PAGE. IT WILL RESULT IN A PIXELATED ORTHOIMAGE. INSTEAD, DOWNLOAD THE IMAGERY BY TILE OR BY COUNTY MOSAIC (2010 - current year).This service depicts true color imagery for the 26 counties representing the Northern Piedmont and Mountains region of North Carolina. This includes the following counties: Alamance, Alexander, Alleghany, Ashe, Avery, Burke, Caldwell, Caswell, Catawba, Davidson, Davie, Forsyth, Guilford, Iredell, Madison, McDowell, Mitchell, Randolph, Rockingham, Rowan, Stokes, Surry, Watauga, Wilkes, Yadkin, and Yancey. The imagery has a pixel resolution of 6 inches and was flown in the beginning of 2018. The RMSE is 1.5 ft X and Y. Individual pixel values may have been altered during image processing. Therefore, this service should be used for general reference and viewing. Image analysis requiring examination of individual pixel values is discouraged. To view the latest imagery for any location in the state, customers should use the "Orthoimagery_Latest" image service (https://services.nconemap.gov/secure/rest/services/Imagery/Orthoimagery_Latest/ImageServer).To find specific dates the images were captured use the imagery dates app or download the data.Metadata:Summary metadata for orthoimagery mosaicsSummary metadata for orthoimagery tilesContractor-specific metadata for Avery, Burke, Caldwell, Madison, McDowell, Mitchell, Yancey countiesContractor-specific metadata for Alexander, Alleghany, Ashe, Catawba, Iredell, Watauga and Wilkes countiesContractor-specific metadata for Davidson, Davie, Forsyth, Rowan, Surry, Stokes, and Yadkin countiesContractor-specific metadata for Alamance, Caswell, Guilford, Randolph, and Rockingham counties

The database contains predicted sea level rise extent layers and baseline layers for the open coast of New Hampshire, the Piscataqua River, and Great Bay based on 2019/2020 LiDAR elevation data.Data comprise the following eleven scenarios:p_MHHW_1_foot_slr: Mean higher high water + 1' sea level risep_MHHW_2_foot_slr: Mean higher high water + 2' sea level risep_MHHW_4_foot_slr: Mean higher high water + 4' sea level risep_MHHW_6_foot_slr: Mean higher high water + 6' sea level risep_MHHW_8_foot_slr: Mean higher high water + 8' sea level risep_MHHW_baseline: baseline elevations from which the MHHW sea level rise layers were derivedp_MHHW_FLOOD_2_foot_slr: Mean higher high water + one percent annual chance flood + 2' sea level risep_MHHW_FLOOD_4_foot_slr: Mean higher high water + one percent annual chance flood + 4' sea level risep_MHHW_FLOOD_6_foot_slr: Mean higher high water + one percent annual chance flood + 6' sea level risep_MHHW_FLOOD_8_foot_slr: Mean higher high water + one percent annual chance flood + 8' sea level risep_MHHW_FLOOD_baseline: baseline elevations from which the MHHW_FLOOD sea level rise layers were derivedThe four data layers that incorporate the 100-year flood are based on the April 2014 preliminary Digital Flood Insurance Rate Maps (DFIRMs) for Rockingham and Strafford Counties.
