This layer package contains GIS data in Esri file geodatabase format. This data is also available for download as a zip archive in shapefile format.Digital parcel files for the Town of Amherst, MA as of December 31, 2013. The Town converted its existing analog tax maps to digital format in 1998. At the time of conversion, tax maps consisted of 108 27"x39" mylar sheets at 1"=100', originally created in 1957 from controlled and rectified photography taken by Air Survey Inc. (VA) in 1956. The tax maps were scanned, and digital line files were created with text annotation. The new line files were then overlayed onto digital color orthophotos produced in 1999, and updated, by first matching road right-of-ways, then adjusting all parcel boundaries. This data set is a spatial view that is created through a one-to-many join between TOA_Parcels_Poly and TOA_CAMA_TABLE. The join is through Map & Lot, which creates stacked parcel polygons in cases where there are multiple block numbers (accounts) for one parcel; this occurs primarily with condominium complexes, as well as with properties with agricultural preservation restrictions. This data set is refreshed on a nightly basis & reflects current information from the Town of Amherst Assessor's Vision Appraisal Database.

The NPRC parcel datalayer contains property (land lot) boundaries and select attributes about each property. NRPC compiled this information over many years from various sources including original tax maps that were subsequently georeferenced and digitized by the Commission. As such, the data is suitable for tax assessment purposes but is not survey-quality.The datalayer contains discrete, non-overlapping polygons. Non-contiguous lot areas are modelled as multi-part polygons. Public rights-of-way and water bodies are stored as non-numbered lots to void the creation of null voids in the parcel fabric. Parcels are edge-matched along town borders. Along the MA state border parcels conform to the Towns from Survey Points datalayer available from MassGIS; in most other cases the parcels are matched to the 1:24K town border datalayer (pba) derived from USGS topo maps and available from NH Granit. In cases where GIS parcel information did not conform to the USGS town boundary linework, NRPC interpreted tax map geography and dimensions and mapped parcel boundaries accordingly.Over time, NRPC has maintained this database by monitoring the Hillsborough County Registry of Deeds online database for recordings related to subdivisions, lot mergers, and lot line revisions. NRPC has maintained a very high match rate between the parcel database and corresponding assessing records. The cardinality between parcels and assessing records is 1:M; the normalized data herein is therefore published in an ESRI relationship class. In some cases, the NRPC edit may precede the corresponding update on the municipal property record card. For this reason, some parcels may not yet have a matching assessing record, or the parcel attributes may not be exactly consistent with the assessing record.

Using digital soils data from the Natural Resources Conservation Service, a series of selections and calculations classified soil associations into 9 different categories of prime forest based ultimately on forest productivity in white pine and red oak. Other data sets were used to refine this classification, including aspect, 1999 land use - land cover, riparian, slope position, wetlands, hydrologic soil association and unique areas. The hydrologic soil associations were based on NRCS information that came as Access files with the soils data. All other data was available from MassGIS.The project “Soil Productivity Mapping for Use in Forest Management” is a digital representation of work done previously in the Department of Natural Resources Conservation at the University of Massachusetts at Amherst. GIS data created for this project followed (where possible) the protocol established in UMass Research Bulletin #705 – Prime Forest Land Classification for Forest Productivity in Massachusetts.Also see https://www.mass.gov/info-details/massgis-data-prime-forest-land for full metadata and access to data download.

This MassGIS Land Use data layer has 21 land use classifications interpreted from 1999 1:25,000 aerial photography. Photointerpretation and automation were done by the Resource Mapping Project at the University of Massachusetts, Amherst. All land use categories were aggregated from 104 categories originally defined in 1971 by Professor William MacConnell at the Dept. of Forestry at UMass Amherst.Please see https://www.mass.gov/info-details/massgis-data-land-use-1951-1999 for more details.Feature service also available.

"The digital topographic map is a United States Geological Survey (USGS) product. The original topographic maps for each county have been scanned and rectified (assigned coordinate information). The collars (the white margins along the sides of the map) have been removed. In addition, all topographic maps for a given county have been tiled together to provide seamless topographic coverage for each locality. The source scale of this product is 1: 4,000. It is available as a Mr. Sid (proprietary format that is “readable” by ArcGIS).For more information on this data refer to the supplemental metadata pdf found at: https://secure-archive.gis.vt.edu/gisdata/public/UnitedStates/Virginia/VCE_2002_metadata/METADATA.pdfThis data has been curated by the Virginia Cooperative Extension at Virginia Tech and Virginia Tech University Libraries.

This map provides information on speed limits that are posted on state-maintained roadways in Virginia. Cities and towns set their own speed limits and these are not available to show on the map. Zoom in on the map to display the speed limits. Speed limits exist for all roads however; where this information is not available for mapping, they are not displayed. Most roads where speed limits are not shown are either rural, secondary roads (routes numbered 600 or greater) where a statutory 55 mph speed limit typically applies, or subdivision streets where a statutory 25 mph speed limit usually applies. These statutory speed limits are often are not posted on these roads. Click on any roadway to display the speed limit information.

"The SSURGO soils data are the most accurate and comprehensive federal soils products available. The levels of soils data include:-SSURGO is the most detailed county-level data. -STATSGO is less detailed statewide map.-NATSGO is a very general soil map of the entire U.S. The SSURGO level of soil mapping is designed for use by landowners, townships, and counties for natural resource planning and management and regional applications. It is appropriate for watershed planning and some agricultural uses. The user should be knowledgeable about soils data and their characteristics. This database is scheduled to be completed for the entire country in 2008. Approximately 85 percent of all counties in Virginia have digital SSURGO soils data available. The Soils section located in the supplemental METADATA file includes an illustration that shows SSURGO soil data (left) and SSURGO soils data made “transparent” and superimposed over aerial photography (right). The SSURGO soil polygons associated with the Virginia County Data Series have been permanently joined with selected attributes. Not all attributes have been joined to the spatial data. These polygon files are disseminated as Shapefiles, and may be large in size (1 to 2 MB).

This layer is a modified version of the 1:24K USGS DLG-derived political boundaries datalayer provided by NH Granit. Subtle deviations in the linework between this layer and Granit's reflect, 1) NRPC's adoption MassGIS's representation of the state boundary between New Hampshire and Massachusetts using survey points, and, 2) areas where town-originated digital parcel data overlapped, in which case the placement of the town boundary is at the estimated midpoint of the overlap, and the digital parcels were then edge-matched accordingly.

More significant discrepancies reflect NRPC's corrections of the town boundaries along two key areas:
• The northern border between Pelham and Hudson: NRPC's depiction agrees with local perambulation records and was reaffirmed through the Towns' joint submission to the U.S. Census Boundary Annexation Survey in 2017.
• The Summer Street area between Milford and Amherst: NRPC's data reflects the outcome of NH Legislation, HB 1248 (2006), which transferred a portion of territory from Amherst to Milford.

Lastly, it should be noted that NRPC's mapping of the entire western border of Lyndeborough along Greenfield and Temple reflects the definition of the town line according to the town's digital parcels provided to NRPC by Cartographic Associates in 2015. It diverges profoundly from the border representation in NH Granit and also U.S.Census (which also differ from each other).
