Description:

Abstract:
METWP250 depicts political boundaries, common town names, and geocodes for Maine at 1:250,000 scale. To correct mapping errors and reflect recent changes to Minor Civil Division (MCD) boundaries, arcs and polygons have been added to or updated in METWP250 where changes are appropriate to the scale of the dataset. Polygons in the dataset are attributed with the items TOWN, COUNTY, GEOCODE, and CNTYCODE as found in "Standard Geographic Codes for Maine Minor Civil Divisions", 1971. The dataset is also attributed with the polygon items LAND, ISLAND, LURC, and TAG. Arcs are coded with the item TYPE. For a current digital copy of "Standard Geocodes for Maine Minor Civil Divisions" in .dbf or comma delimited text format see http://megis.maine.gov/catalog/ "Tables".
Purpose:
METWP250 was created to show political boundaries, common town names and Maine geocodes at 1:250000 scale. Users must assume responsibility in determining the usability of this data for their purpose. Data at this scale is suitable for regional studies and planning. Not for use in scales greater than 1:250000.

Other Citation Details:
This citation is for the first official Standard Geographic Code endorsed and adopted by the Governor of Maine, on July 1, 1971. Geocodes have undergone subsequent revisions, all of which were "officially" rolled back to this 1971 list by Maine's Information Services Policy Board (ISPB), as of January 2000. In 1971, all Maine state agencies were requested to implement these five digit geocodes, in agency information systems, to build a base of data for Maine's Minor Civil Divisions (MCDs) and to promote data sharing. Data coded by MCD may subsequently be summarized by any other type of region, administrative district, natural area, etc. The first two digits of the geocode represent the federal code (FIPS) for Maine counties, the remaining three digits uniquely identify each of Maine's MCDs and Reservations. As an information service to state agencies and the public, geocodes for Maine, are now maintained, updated and made available for download, in comma delimited text and .dbf format, through the Maine Office of Geographic Information Systems (MEGIS) Data Catalog at http://megis.maine.gov/catalog/ , "Tables" link.

Process Description:
The Maine Office of GIS completed the conversion of all final data layers from NAD27 to NAD83 in July 1999. All the data layers were converted using the ArcInfo (version 7.2.1) NADCON conversion and the "project" command. All data was copied to double precision, projected to NAD83, and then copied back to single precision. It was decided to keep the NAD27 quad structure instead of generating new quad boundaries from NAD83 coordinates - all indexes (quads) were projected to NAD83 by using the same process previously described. All MEGIS data libraries in ArcInfo Librarian were repopulated using the NAD83 indexes and data.

Overview Description:

Entity and Attribute Overview:
Polygons in METWP250 are attributed with the items TOWN, COUNTY, GEOCODE, and CNTYCODE as found in "Standard Geographic Codes for Maine Minor Civil Divisions", 1971. The coverage is also attributed with the polygon items LAND, ISLAND, LURC, and TAG. Arcs are coded with the item TYPE. For a current digital copy of "Standard Geocodes for Maine Minor Civil Divisions" in .dbf or comma delimited text format see http://megis.maine.gov/catalog "Tables".
Entity and Attribute Detail Citation:
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.

Format Name: ESRI Shapefile
Format Version Number: ARC Version 9.x
Format Specification: ArcView Shapefile Format
Format Information Content:
MEGIS has made all vector layers, in the Maine GIS Internet Data Catalog, available in ESRI's ArcView shapefile format. A shapefile is a simple non-topological format that stores the geometry and attribute information for a set of geographic features as a set of vector (point, line, polygon) coordinates. Shapefiles draw quickly and directly in ArcView, ArcGIS, ArcExplorer. Shapefiles are a compatible data type for many other types of GIS software. Three files are fundamental to each shapefile: .shp stores the feature geometry (shape and location information); .shx stores the index of the feature geometry; .dbf a dBASE (TM) file stores the attribute information for the features. Other index files may be created to help speed analysis and query: these file formats are .sbn .sbx .ain .aix .fbn and .fbx. In addition you may find projection .prj, and metadata .xml, files associated with shapefiles.
