The dataset provides a ready reference for county boundaries, names and county codes at 1:24,000 scale. Not for use at scales larger than 1:24,000. Data at this scale is suitable for detailed studies and local planning.
CNTY24 contains state and county boundaries for Maine, mapped at 1:24,000 scale. The dataset has polygon topology and was created in Arc/Info from METWP24 by a select on arcs coded TYPE = state, county, and coastline.
Credit should always be given to the data source and/or originator when the data is transferred or printed.
Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the correct copy of both data and metadata from the Maine GIS Data Catalog. Updates, corrections, and feedback, incorporated in the Maine GIS database are made in accordance with "Data Standards for Maine Geographic Information Systems", 2002, and coordinated by MEGIS.

Official Maine county name

Code corresponds to the federal (FIPS) code established for each of Maine's sixteen counties. The county code is also represented in the first two digits of Maine's official "Standard Geographic Code (geocode) a five digit code that uniquely identifies minor civil divisions and indian reservations in the Maine

Feature geometry.
ESRI
A field of type UUID (Universal Unique Identifier) in which values are automatically assigned by the geodatabase when a row is created. The GlobalID field is necessary for maintaining object uniqueness across replicas. All feature classes and tables participating in one-way or two-way replication must contain the GlobalID field. This field is not editable and is automatically populated when it is added for existing data.

CNTY24 contains state and county boundaries for Maine. The coverage has polygon topology and was created in Arc/Info from METWP24 by a select on arcs coded TYPE = state, county, and coastline. Polygons in the coverage are labeled with COUNTY, CNTYCODE, TAG, LAND, ISLAND. Arcs in the coverage are coded for TYPE and LAND. Please note recommended feature level metadata items FMSRC, FMSRCORG, FMSRCDAT, FMPROCSS, FMUPDORG, FMUPDDAT have been added to the arc coding of this coverage to replace the item SOURCE. These items are intended for use in providing specific information about the source of changes to the location of arc features in the coverage and contain codes that cross reference the elements Source Citation Abbreviation, Source Publication Date, Process Step, Process Contact and Process Date in Federal Geographic Data Committee(FGDC) compliant metadata for the coverage. For more information related to feature level metadata see http://www.maine.gov/megis/policies/
The ArcView shapefile and ArcGIS geodatabase formats, commonly used for Maine GIS data, carry default identifiers and attributes that are software generated and/or important for internal recordkeeping. These are listed here to avoid repetition for every layer, and may not be repeated in the attribute descriptions and definitions of each layer. Common software generated identifiers and attributes in Maine GIS data include: FID (feature identifier), Shape (feature geometry), OBJECTID and SHAPE_lengt. In addition, most GIS formats will carry fields for PERIMETER, AREA and/or LENGTH according to feature geometry. These fields are typically available by default, with the units based on coordinate system or projection units of GIS data. Most GIS software packages also provide a means to calculate these values. It is important to test any columns containing PERIMETER, AREA or LENGTH values before using them for analysis purposes. These important values can be carried from format to format and become out-dated. Verify that the values are correct. Also, in your GIS software, please view the properties of data layers for the map units used to calculate these fields, and for the units set for display purposes.
