A web map used to visualize available digital parcel data for Organized Towns and Unorganized Territories throughout the state of Maine. Individual towns submit parcel data on a voluntary basis; the data are compiled by the Maine Office of GIS for dissemination by the Maine GeoLibrary, and where available, the web map also includes assessor data contained in the Parcels_ADB related table.This web map is intended for use within the Maine Geoparcel Viewer Application; it is not intended for use as a standalone web map.Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. Maine Parcels Organized Towns and Maine Parcels Organized Towns ADB are the product of these voluntary submissions. Communities provide updates to the Maine GeoLibrary on a non-regular basis, sometimes many years apart, which affects the currency of Maine GeoLibrary parcels data. Another resource for real property transaction data is the County Registry of Deeds, although organized town data should very closely match registry information, except in the case of in-process property conveyance transactions.

The Maine Geoparcel Viewer Application allows users to search and view available digital parcel data for Organized Townships and Unorganized Territories in the State of Maine. The Maine GeoLibrary and the Maine Office of GIS do not maintain parcel data for communities, cannot verify parcel ownership, and are not responsible for individual parcel data verification or updating emergency records concerning parcel addresses. If you have questions about a specific parcel, please contact the appropriate Town Office or County Registry of Deeds for the most up-to-date information.Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. The "Maine Parcels Organized Towns Feature" layer and "Maine Parcels Organized Towns ADB" table are the product of these voluntary submissions. Communities provide updates to the Maine GeoLibrary on a non-regular basis, which affects the currency of Maine GeoLibrary parcels data; some data are more than ten years old. Please contact the appropriate Town Office or the County Registry of Deeds for more up-to-date parcel information. Organized Town data should very closely match registry information, except in the case of in-process property conveyance transactions.In Unorganized Territories (defined as those regions of the state without a local government that assesses real property and collects property tax), Maine Revenue Services is the authoritative source for parcel data. The "Maine Parcels Unorganized Territory" layer is the authoritative GIS data layer for the Unorganized Territories. However, it must always be used with auxiliary data obtained from the online resources of Maine Revenue Services to compile up-to-date parcel ownership information.

This feature layer provides digital tax parcels for the Organized Towns of the State of Maine. Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. "Maine Parcels Organized Towns Feature" and "Maine Parcels Organized Towns ADB" are the product of these voluntary submissions. Communities provide updates to the Maine GeoLibrary on a non-regular basis, which affects the currency of Maine GeoLibrary parcels data. Another resource for real property transaction data is the County Registry of Deeds, although organized town data should very closely match registry information, except in the case of in-process property conveyance transactions. In Unorganized Territories (defined as those regions of the state without a local government that assesses real property and collects property tax), the Maine Revenue Service is the authoritative source for parcel data. "Maine Parcels Unorganized Territory Feature" is the authoritative GIS data layer for the Unorganized Territories. However, it must always be used with auxiliary data obtained from the online resources of Maine Revenue Services (https://www.maine.gov/revenue/taxes/property-tax) to compile up-to-date parcel ownership information. Property maps are a fundamental base for many municipal activities. Although GIS parcel data cannot replace detailed ground surveys, the data can assist municipal officials with functions such as accurate property tax assessment, planning and zoning. Towns can link maps to an assessor's database and display local information, while town officials can show taxpayers how proposed development or changes in municipal services and regulations may affect the community. In many towns, parcel data also helps to provide public notices, plan bus routes, and carry out other municipal services.

This dataset contains municipality-submitted parcel data along with previously developed parcel data acquired through the Municipal Grants Project supported by the Maine Library of Geographic Information (Maine GeoLibrary). Grant recipient parcel data submissions were guided by standards presented to the Maine GeoLibrary Board on May 21, 2005, which are outlined in the "Standards for Digital Parcel Files" document available on the Maine GeoLibrary publications page (https://www.maine.gov/geolib/policies/standards.html). This dataset also contains municipal parcel data acquired through other sources; the data sources are identified (where available) by the field “FMSCORG”. Note: Join this feature layer with the "Maine Parcels Organized Towns ADB" table (https://maine.hub.arcgis.com/maps/maine::maine-parcels-organized-towns-feature/about?layer=1) for available ownership information. A date field, “FMUPDAT”, is attributed with the most recent update date for each individual parcel if available. The "FMUPDAT" field will not match the "Updated" value shown for the layer. "FMUPDAT" corresponds with the date of update for the individual data, while "Updated" corresponds with the date of update for the ArcGIS Online layer as a whole. Many parcels have not been updated in several years; use the "FMUPDAT" field to verify currency.

The 2022 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The cartographic boundary files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located. The boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs is that they must contain some housing and population. The generalized boundaries of most incorporated places in this file are based on those as of January 1, 2022, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The generalized boundaries of all CDPs are based on those delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

This parcel map viewer primary use is to identify ones parcel information such as taxes, property pics, assessor value and etc.

Park Boundary polygons for Acadia National Park, Maine. Use attributes to distinguish between lands in fee-ownership, lands still to be acquired in fee-ownership in accordance with Public Law 99-420 or Public Law 97-335 (inholdings or acquisition parcels), or conservation easements. Conservation easement lands held by the NPS are still in private ownership and are generally not open to public access; please observe landowner rights. NOTE: for official land status information, please contact the NPS Lands Office. This layer is produced, maintained, and used by Acadia National Park for cartographic purposes because it fits well with other local data. It does not represent an official or surveyed boundary and should not be used for land transaction purposes. Lines representing the current fee-ownership boundary (approximate) for Acadia National Park. USERS PLEASE NOTE: Lines are considered estimates only and should not be used for transactions and/or legal descriptions, only for general depictions of land holdings. This data layer, for cartographic purposes, has been adjusted to match local municipal tax parcel maps which are of varying accuracy and may not match survey information where it exists. Data layers are provided in shapefile format.

The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public open space and voluntarily provided, private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastral Theme (http://www.fgdc.gov/ngda-reports/NGDA_Datasets.html). PAD-US is an ongoing project with several published versions of a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public open space and other protected areas. Most areas are public lands owned in fee; however, long-term easements, leases, and agreements or administrative designations documented in agency management plans may be included. The PAD-US database strives to be a complete “best available” inventory of protected areas (lands and waters) including data provided by managing agencies and organizations. The dataset is built in collaboration with several partners and data providers (http://gapanalysis.usgs.gov/padus/stewards/). See Supplemental Information Section of this metadata record for more information on partnerships and links to major partner organizations. As this dataset is a compilation of many data sets; data completeness, accuracy, and scale may vary. Federal and state data are generally complete, while local government and private protected area coverage is about 50% complete, and depends on data management capacity in the state. For completeness estimates by state: http://www.protectedlands.net/partners. As the federal and state data are reasonably complete; focus is shifting to completing the inventory of local gov and voluntarily provided, private protected areas. The PAD-US geodatabase contains over twenty-five attributes and four feature classes to support data management, queries, web mapping services and analyses: Marine Protected Areas (MPA), Fee, Easements and Combined. The data contained in the MPA Feature class are provided directly by the National Oceanic and Atmospheric Administration (NOAA) Marine Protected Areas Center (MPA, http://marineprotectedareas.noaa.gov ) tracking the National Marine Protected Areas System. The Easements feature class contains data provided directly from the National Conservation Easement Database (NCED, http://conservationeasement.us ) The MPA and Easement feature classes contain some attributes unique to the sole source databases tracking them (e.g. Easement Holder Name from NCED, Protection Level from NOAA MPA Inventory). The "Combined" feature class integrates all fee, easement and MPA features as the best available national inventory of protected areas in the standard PAD-US framework. In addition to geographic boundaries, PAD-US describes the protection mechanism category (e.g. fee, easement, designation, other), owner and managing agency, designation type, unit name, area, public access and state name in a suite of standardized fields. An informative set of references (i.e. Aggregator Source, GIS Source, GIS Source Date) and "local" or source data fields provide a transparent link between standardized PAD-US fields and information from authoritative data sources. The areas in PAD-US are also assigned conservation measures that assess management intent to permanently protect biological diversity: the nationally relevant "GAP Status Code" and global "IUCN Category" standard. A wealth of attributes facilitates a wide variety of data analyses and creates a context for data to be used at local, regional, state, national and international scales. More information about specific updates and changes to this PAD-US version can be found in the Data Quality Information section of this metadata record as well as on the PAD-US website, http://gapanalysis.usgs.gov/padus/data/history/.) Due to the completeness and complexity of these data, it is highly recommended to review the Supplemental Information Section of the metadata record as well as the Data Use Constraints, to better understand data partnerships as well as see tips and ideas of appropriate uses of the data and how to parse out the data that you are looking for.

METWP24P depicts political boundaries for all Organized Towns and Unorganized Territories in Maine at 1:24,000 scale. The layer also includes common town names and authoritative geocodes. The layer was created using the USGS 7.5-minute map series and the Maine GIS base layer COAST, which contains Maine's coastal Mean High Water (MHW) mark and Maine islands. To correct mapping errors and reflect changes to Minor Civil Division (MCD) boundaries, arcs and polygons were added or updated using the following data sources: photorevised USGS data; Maine GIS base layer coincident features; legal descriptions; GPS data; and Maine Department of Transportation (MEDOT) engineering plans. METWP24P also contains USGS 1:100,000-scale data and U.S. Department of Commerce Census Bureau TIGER Line Files from 1990 and 2000 where these provide a more correct or best available representation of a feature in question.

This dataset contains boundary layers for the Aroostook National Wildlife Refuge in Maine.

National Wildlife Refuges are federal lands managed by the U.S. Fish and Wildlife Service (USFWS). The primary source for boundary information is the USFWS Realty program (status maps, legal surveys). An effort by the USFWS Region 5 (northeast states -ME,NH,VT, MA, RI, CT, NY, PA, NJ, MD, DE, WV, VA) Realty Division, Cartography and Spatial Data Services Branch has resulted in digital refuge boundaries for all refuges in the northeast at a scale of 1:24,000.

The purpose of this dataset is to serve as a spatial reference of refuge boundaries for other data layers in GIS and mapping applications. It is specifically not intended to be used as a land survey or representation of land for conveyance or tax purposes.

Status maps were registered to geographic coordinates, boundaries were digitized and labeled. Digital files were updated using survey and collateral data for newly acquired tracts, then stepped through 3 levels of quality-control review for spatial and thematic accuracy.

The 2015 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The records in this file allow users to map the parts of Urban Areas that overlap a particular county. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint." There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain leading zeroes. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. The boundaries for counties and equivalent entities are as of January 1, 2010.

This dataset contains boundary layers for Rachel Carson National Wildlife Refuge: Biddeford Pool Division.

METWP24L depicts political boundaries for all Organized Towns and Unorganized Territories in Maine at 1:24,000 scale. The layer also includes common town names and authoritative geocodes. The layer was created using the USGS 7.5-minute map series and the Maine GIS base layer COAST, which contains Maine's coastal Mean High Water (MHW) mark and Maine islands. To correct mapping errors and reflect changes to Minor Civil Division (MCD) boundaries, arcs and polygons were added or updated using the following data sources: photorevised USGS data; Maine GIS base layer coincident features; legal descriptions; GPS data; and Maine Department of Transportation (MEDOT) engineering plans. METWP24L also contains USGS 1:100,000-scale data and U.S. Department of Commerce Census Bureau TIGER Line Files from 1990 and 2000 where these provide a more correct or best available representation of a feature in question.

This layer is a subset of the Maine Conserved Lands layer. The full dataset is here. The conserved lands layer is an inventory of Maine’s terrestrial protected areas that are dedicated to the preservation of biological diversity and to other natural, recreation and cultural uses, and which are managed for these purposes through legal or other effective means. Conserved Lands contains conservation lands ownership boundaries at 1:24,000 scale for Maine land in federal, state, municipal and non-profit ownership with easements. State, county, town, and coast boundary data were obtained from MEGIS town boundary dataset METWP24. 1:24,000 US Geological Survey (USGS) digital line graph data was used for hydrography and transportation features. Where state, county, and town boundaries were coincident with property boundaries, the coincident features were taken from METWP24. Where hydrography, roads, railroads and power-lines were coincident with property boundaries, the coincident features were taken from 1:24,000 digital line graph data. The ownership lines do not represent legal boundaries nor are the ownership lines a survey. Conserved Lands is an inventory of approximate property boundaries.Conserved Lands was created to provide GIS coverage for the conservation lands database. The ownership lines do not represent legal boundaries nor are the ownership lines a survey. The data contained in Conserved Lands is an inventory only. Users must assume responsibility in determining the usability of this data for their purposes. Data at this scale is suitable for local and regional planning. Original mapping was produced in 1989, updated in 1993 by R.D. Kelly Jr. of the State Planning Office. Data is continually updated.

Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. Maine Parcels Organized Towns and Maine Parcels Organized Towns Aux Data are the product of these voluntary submissions. Communities provide updates to Maine GeoLibrary on a non-regular basis, which affects the currency of Maine GeoLibrary parcels data. Another resource for real property transaction data is the County Registry of Deeds, although organized town data should very closely match registry information, except in the case of in-process property conveyance transactions.To provide a statewide digital tax parcel dataset for Maine. Property maps are a fundamental base for many municipal activities. Although GIS parcels data cannot replace detailed ground surveys, the data can assist municipal officials with functions such as accurate property tax assessment, planning and zoning. Towns can link maps to an assessor's database and display local information. Officials can show tax-payers how proposed development or changes in municipal services and regulations may affect the community. In many towns, parcels data also helps to provide public notices, plan bus routes, and carry out other municipal services.This dataset contains municipal parcels data along with previously developed parcel data acquired through the municipal grants project by Maine Library of Geographic Information (MLGI). Submission of the municipal grant recipient parcels data was guided by standards presented to the MLGI Board, May 21, 2005, "Standards for Digital Parcel Files" A date field FMUPDAT is attributed with the most recent update date. This dataset also contains municipal parcel data acquired through other sources, the data sets are differenciated by the item FMSCORG.

The polygon parcel layer is created from townships within Maine Revenue Services (MRS) unorganized territories as well as individual plantation and town parcel information within Land Use Planning Commission (LUPC) jurisdiction. The plantation and town parcel information is infrequently updated. The tax owner information is received from each town and plantation separately and could be as much as 5 years out of date.

The Maine Land and Water Conservation Fund feature layer contains a point, line, and polygon layer. The features represent project sites, boundaries, and trails that have benefited from the Land and Water Conservation Fund. These areas must be maintained for public outdoor recreation in perpetuity.The project boundary lines do not represent legal boundaries nor are the boundary lines a survey. Maine Land and Water Conservation Fund map is an inventory of project boundaries.For more information about the Land and Water Conservation Fund please visit: Maine Grants & Community Recreation or contact the Community Grants Program.Doug Beck, Outdoor Recreation Program Manager, Doug.Beck@maine.govMat Henion, Outdoor Recreation Grants Specialist, Mathew.B.Henion@maine.govCatherine Dufault: LWCF Stewardship Specialist, Catherine.Dufault@maine.gov

Wildlife Management Areas (WMAs)The mission and purpose of the State owned WMAs is to provide a statewide, ecologically based system of land holdings for the protection and enhancement of important wildlife habitats that also provide opportunities for all types of public recreation, where those forms of recreation do not unduly impact the wildlife resources.Wildlife Management Areas are a subset of the Conserved Lands feature layer:Conserved Lands contains conservation lands ownership boundaries at 1:24,000 scale for Maine land in federal, state, municipal and non-profit ownership with easements.
