Publication Date: 20021029 Title: blks00 Edition: 2 Geospatial Data Presentation Form: vector digital data Series Information: Series Name: Maine GIS Data Catalog; Maine GIS SDE Server Issue Identification: Census 2000 Redistricting Data Publication Information: Publication Place: Augusta ME Publisher: Maine Office of Geographic Information Systems (MEGIS) Other Citation Details: 100000 ArcInfo version 8.0.1, Solaris 7, pathname = /home11/crypt83/counties//blks00, coverage size = ~3.5 MB (Penboscot sample) BLKS00 contains Census Blocks which are the smallest geographic units for which basic demographics are available from the Census Bureau. In addition, MEGIS has published two of the geographies as single themes, MCDCCD00 and VTD00 offer Census 2000 County Subdivisions and Census 2000 Voting, House, Senate and County Commissioner districts for Maine. All the datasets are attributed with population. Unique-ids for each Census geographic unit can be used to relate or join these datasets to extended Census data files, counts, tabulations, and reference tables. Two such tables that relate to BLKS00 are MEGEO and BLKS00SF1, from the Bureau of Census, have been published at the MEGIS Data Catalog "Tables" link at . Additional tables from the Census Bureau will be published as they become available. CAUTION: BLOCK, BLOCK GROUP, TRACT and VTD numbers alone are not unique. The STFIDBLK00 is the unique reference for BLOCKS statewide. The item CENTAG applies only to multiple ocurrences of STFIDBLK00. Beyond mapping, care must be taken to ensure referential integrity in relates and joins to the other IDs provided. Online Linkage: http://megis.maine.gov/catalog/ Description: Abstract: BLKS00 contains Census 2000 Block boundaries and population by blocks for the state of Maine at 1:100,000 scale. Census Block boundaries are statistical subdivisions of counties for the reporting of decennial census data. The Census 2000 TIGER/Line Files are the primary source for this data set. BLKS00 is built to POLYGON topology and contains the attributes FIPSSTCO, COUNTY, COUSUB00, TRCT00, BLKGRP00, PLC00, VTD00, BLK00, BLK00NUM, BLKNAME, POP00, CENTAG and STFIDBLK00. The item STFIDBLK00 is a calculated combination of these items that uniquely identifies a Census Block within the State of Maine. The item CENTAG was added for correct labeling and/or statistics where multiple polygons contain the same block number, as is the case in some coastal communities where islands are depicted. The numeric item POP00 was populated and proofed from the Census 2000 Redistricting Data (P.L. 94-171) Summary File. The item COUSUB00 contains the Federal Information Processing Standard (FIPS) code a single 5 character code field used by the Bureau of the Census to identify the Census County Division to which the block belongs. Likewise TRCT00 (Tract), BLKGRP00 (Block Group), VTD00 (Voting District), and PLC00 (Designated Place if applicable). All Census geographies, cross tabulated in the dataset, can be mapped using the ID included for each level, i.e. For Census County Subdivisions COUSUB00, Census Tracts STFIDTRCT00, Census Block Groups STFIDBLKGRP00, Census Designate Places PLC00, and Voting Districts VTD00ID. Unique-ids for each Census geographic unit can be used to relate or join these datasets to extended Census data files, counts, tabulations, and reference tables. For more information on related files that have been published at the Maine GIS Data Catalog see the "Tables" link at http://megis.maine.gov/catalog/ . Purpose: BLKS00 was created to facilitate mapping, analysis, and use of Census 2000 data with other Maine GIS data layers. Other data layers for use with this Census geography data set will be published. Although Census boundaries represent real world features like rivers, lakes, railroads, political boundaries, etc., their primary purpose is for use in statistical analysis. As such, the features of the Census TIGER/Line Files from which this coverage was derived may not coincide with representations of these features drafted for other purposes or at other map scales. Supplemental Information: CAUTION: BLOCK, BLOCK GROUP, TRACT and VTD numbers alone are not unique. The STFIDBLK00 is the unique reference for BLOCKS statewide. The item CENTAG applies only to multiple occurrences of STFIDBLK00. Beyond mapping, care must be taken to ensure referential integrity in relates and joins to the other IDs provided. There is often no direct 1:1 relationship between minor civil division boundaries and Census geographic units. The rural character of Maine, and especially northern Maine, requires the Census Bureau to report counts and tabulations over larger areas for statistical reasons and the Bureau of Census redefines these areas as population shifts. MCDCCD00 represents the closest correlation between Census geographic units and minor civil division boundaries. All other Census geographies represent areas either larger or smaller than town or township boundaries and often cross boundaries. In most cases additional analysis will be required to report Census counts and tabulations by town or township.

Completeness Report: Data set 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. An insignificant number of blocks (limited to less than a dozen statewide) required reshaping to display properly in a single precision coverage. Reshape was done manually well within the map accuracy standard (less than 10 meters) for data at this scale.

Process Step: Process Description: BLKS00 was assembled from Redistricting TIGER/Line 2000 data for Maine counties published in shapefile format by ESRI through the Geography Network at . The ESRI data layers were in county map extents, stored in geographic coordinates expressed as decimal degrees. The coordinates provided were in the North American Datum of 1983 (NAD83). The ESRI shapefiles were projected to UTM, NAD83, Zone 19 in ArcView 3.2.1, then converted to Arc/Info coverage format with the SHAPEARC command. PRECISION was set to double, double and tolerances were reset throughout the conversion process. The final copy of the coverage was returned to single precision with the result an excellent linework match to the Redistricting 2000 TIGER/Line File source. The coverage was built to POLYGON topology. Attributes of the ESRI shapefiles preserved in BLKS00 are the state and county FIPS codes in FIPSSTCO. Other items include TRCT00, BLKGRP00, PLC00, VTD00 to provide cross-reference to other published Census geography layers. To facilitate analysis the Census Block number is provided in both text BLK00 and numeric BLK00NUM format, the item CENTAG was added for correct labeling and/or statistics where multiple polygons contain the same Census Block number as is the case in some coastal communities where islands are depicted. The item COUSUB contains the Federal Information Processing Standard (FIPS) code a single 5 character code field used by the Bureau of the Census to identify the Census County Division to which the block belongs. Likewise TRCT00 (Tract), BLKGRP00 (Block Group), VTD00 (Voting District), and PLC00 (Designated Place if applicable). The item STFIDBLK00 is a calculated combination of these items that uniquely identifies a Census Block within the State of Maine.

Standard Order Process: Digital Form: Digital Transfer Information: Format Name: ARCE Format Version Number: ARC Version 8.3 Format Specification: ARC/INFO Export Format ASCII File Structure: Case Sensitive: false Format Information Content: An Arc/Info export file is an interchange format used to transfer spatial data, INFO data files, and other ESRI ARC/INFO files between various machine types. Export files have the suffix .e00 and contain, in fixed-length ASCII format, all spatial information available for each feature. The command IMPORT is available in A/I to convert the export file to original format, i.e. coverage, grid, or other spatial data file. Import will add a spatial data file and a related INFO file to a machine directory. ESRI's ArcView is packaged with an import utility called IMPORT71 for the same export file conversion. The utility is also available through the FREE software link on the Maine GIS Data Catlaog under "CDProducts" at http://megis.maine.gov/catalog/ or from ESRI at http://www.esri.com/. CARE MUST BE TAKEN after import, not to separate the spatial information from its related INFO file. Since export files are in ASCII format make sure any file transfer method like FTP is executed under ASCII mode. Binary transfer will not work correctly.

Digital Form: Digital Transfer Information: Format Name: ESRI Shapefile Format Version Number: ARC Version 8.3 Format Specification: ArcView Shapefile Format ASCII File Structure: Case Sensitive: false Format Information Content: MEGIS will soon make all data in the internet Data Catalog available in ESRI's ArcView shapefile format. This additional format will first be available for E911 data under the TOWNS tab. 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; you can create your own data using the shapefile format; an existing ARC/INFO coverage can be converted to a shapefile; other spatial data formats can be converted to shapefiles. Three files are created for 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. CAUTION: When you edit an existing theme or shapefile you are creating a new dataset or at least a new version of a dataset; give the dataset a new name or a version identifier to reflect your edits. Be prepared to fully document your sources and to both quantify and qualify the edits you make in order to facilitate coordination with other data sources. PLEASE NOTE: conversion to shapefile format changes some characters ( # - .) to underscores; item names over 10 characters are truncated. An effort will be made over time to consider these limitations in item names, and to eliminate the use of these characters in Maine GIS data development. It should not be assumed that a conversion from shapefile back to coverage would produce the same data file as found in the original coverage format. The results of such a conversion are greatly improved by the use of PRECISION setting DOUBLE, DOUBLE and careful management of tolerances.
