1:100000 HOUSE03 replaces previous Maine GIS data depicting Maine House of Representatives Districts, i.e. the dataset VTD00, HOUSE, and voting district attribution in BLKS00, which refer to Maine House District boundaries, prior to September 13, 2003. For more information on Maine electoral districts and an overview of the apportionment process in Maine see http://www.maine.gov/sos/cec/elec/apport/apport.htm and http://www.maine.gov/sos/cec/elec/apport/overview.htm .

Description:
Abstract:
HOUSE03 contains Maine House of Representative Districts established by the Maine Legislature. Legislation, Chapter 289 of the Public Laws of 2003, was enacted by the 121st Legislature and signed by the Governor on May 23, 2003. The dataset, in accordance with the legislation, depicts district boundaries following US Census Bureau TIGER/Line Files 2000 mapped at 1:100,000. These districts are in effect for candidates participating in the June 8, 2004 Primary Election and November 2, 2004 General Election.
Dataset polygons are assembled into REGIONS that represent 151 Maine House of Representative Districts and are attributed, in the item HSDSTRCT03, with the House District number prefixed by 23 the Federal Information Processing Code for Maine. Additional attribution on the demographics of the districts including population, race, age, and household characteristics contains classification and content similar to but slightly different from US Census Bureau, Census 2000, Summary File 1. See SF1 for fields definition http://www.census.gov/prod/cen2000/doc/sf1.pdf .
Purpose:
HOUSE03 has been published as a Maine GIS layer to provide a digital copy of Maine's newly apportioned electoral districts to all Maine GIS users. The dataset is suitable for use with Maine GIS data derived from TIGER/Line Files 2000, i.e. BLKS00, MCDCCD00 and US Census Bureau data.
Supplemental Information:
For additional information on Maine electoral districts see the website of the Maine Department of Secretary of State, Bureau of Corporations, Elections, and Commissions, http://www.maine.gov/sos/cec/elec/apport/apport.htm .

Data Quality Information
Section Index
Attribute Accuracy:
Attribute Accuracy Report: Attribute accuracy is expected to be excellent. Content can be confirmed by comparison to statistical data available directly from the US Census Bureau.
Logical Consistency Report: Spatial topology meets "Data Standards for Maine Geographic Information Systems", June 2002.
Completeness Report: The dataset is complete.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
Approximate horizontal accuracy is 51 meters, assuming source data meets National Map Accuracy Standards for 1:100,000 scale. The data compiles perfectly with US Census Bureau TIGER/Line File 2000 data which is the assumed source.
Quantitative Horizontal Positional Accuracy Assessment:
Horizontal Positional Accuracy Value: 51
Horizontal Positional Accuracy Explanation:
This geospatial data layer is derived from Census 2000 TIGER/Line files. The information present in TIGER/Line files is provided for the purposes of statistical analysis and census operations only. Coordinates in the TIGER/Line files have six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest. The positional accuracy varies with the source materials used, but generally the information is no better than the established national map Accuracy standards for 1:100,000-scale maps from the U.S. Geological Survey (USGS); thus it is NOT suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface.

TIGERS (Topologically Integrated Geographic Encoding and Referencing) are a public product of the Bureau of the Census. TIGERS represent a digital database of geographic features, such as roads, railroads, rivers, lakes, political boundaries, census statistical boundaries, etc. covering the entire United States. The database contains information about these features such as their location in latitude and longitude, the type of feature, the geographic relationship to other features, and other related information. In order for others to use the information in the Census TIGER database in a geographic information system (GIS), the Census Bureau releases periodic extracts of the database, including the TIGER/Line Files, to the public.

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 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.
