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 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.

The Maine Constitution requires the Legislature to reapportion legislative districts every ten years, using the most recent census data. The State of Maine has typically done this the 3rd year following the Census. This dataset indicates the result of the 2013 reapportionment for the Senate.These data are derived primarily from the Maine towns boundary dataset to indicate the Senate districts starting with the 127th Legislature. Since many districts are defined by census tracts and blocks, where these boundaries split up towns, the lines from the census data were used to do so. These districts become public law on October 9, 2013, but the legislation specifically delays the implementation of these districts until the 127th Legislature (Dec 3 2014).These data are based on 1:24,000 base data and will inherit the resulting spatial inaccuracies of the source data. These data are intended for mapping at scales suitable for 1:24,000 scale and are not intended to be a ground survey of precise boundaries. Typically boundaries follow town lines, or roads or water features. In some cases these lines may have have slight variations from the actual features which delineate the legislative district.

description: Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitized contour lines either by following the lines or by choosing the intersection of the contour and flight-line to create a value of the magnetic field. The values presented are latitude, longitude, and map magnetic-field values.; abstract: Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations.

Forest Ecosystem Dynamics Multisensor Airborne Campaign (FED MAC): Stem Map of Spruce Site

 The Biospheric Sciences Branch (formerly Earth Resources Branch)
 within the Laboratory for Terrestrial Physics at NASA's Goddard Space
 Flight Center and associated University investigators are involved in
 a research program entitled Forest Ecosystem Dynamics (FED) which is
 fundamentally concerned with vegetation change of forest ecosystems at
 local to regional spatial scales (100 to 10,000 meters) and temporal
 scales ranging from monthly to decadal periods (10 to 100 years). The
 nature and extent of the impacts of these changes, as well as the
 feedbacks to global climate, may be addressed through modeling the
 interactions of the vegetation, soil, and energy components of the
 boreal ecosystem.

 Location, Diameter at breast height, height, and canopy position of
 several tree species were measured on the site located along the
 Howland-Edinburgh, Maine Townline approximately 180 m west of the
 Gunbarrel Road within the International Paper's Northern Experiment
 Forest.

Maine Town Points (METWP24PT) provides a point data layer that identifies all Organized Towns and Unorganized Territories in the State of Maine. The layer also contains municipality names and county names, including authoritative geocode identifiers. Point locations correspond to the centroid of the town boundary, not the actual physical location of the municipality or township.

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.Conservation organizations, land trusts, and municipalities can submit new or updated fee ownership or easement parcels to the statewide Conserved Lands layer by emailing a shapefile to Tracy Scopel, tracy.scopel@maine.gov. Please use the same attribute fields in the shapefile and follow the guidance for populating the data in the Conserved Lands Layer Attributes Handout. Please indicate for each parcel polygon whether it is a new addition or an edit of an existing feature. If editing a feature please make sure the CL_UNIQUEID value from the existing feature in Conserved Lands is included.

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.

METWP24PD depicts dissolved political boundaries for all Organized Towns and Unorganized Territories in Maine at 1:24,000 scale. "Dissolved" means that municipalities or townships with multiple disconnected entities (ex. islands) are grouped as multipart polygons in a single geometry with the appropriate municipality or township label and attribute data. This approach reduces the number of labels required and improves layer drawing performance for low-bandwidth environments. Example: a town has 430 distinct island entities that are all labeled as "town" in addition to the municipality itself. When dissolved, it has only one geometry that includes all 430 entities' combined area and attributes with the municipality, and one label of "town". METWP24PD includes common town names and authoritative geocodes in its attribute information. 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.

The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding is that data users think census blocks are used geographically to build all other census geographic areas, rather all other census geographic areas are updated and then used as the primary constraints, along with roads and water features, to delineate the tabulation blocks. As a result, all 2010 Census blocks nest within every other 2010 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Census blocks cover all territory in the United States, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands). Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. A block may consist of one or more faces.
