Description:

Abstract:
COAST depicts Maine's coastline at mean high water, based on USGS 1:24,000 scale quadrangles. Some New Hampshire and New Brunswick coastlines are also included. Data for this coverage were digitized from the Mean High Water (MHW) line as shown on USGS 1:24,000 scale quadrangle maps. In addition, tidal rivers and ponds are also included in this coverage. The extent of tidal features was determined by a group of marine specialists familiar with Maine's coast. For rivers where the tidal extent was unclear the first contour or bridge crossing the river was used. Features which may be tidal but were connected to the coast by single line streams are not included in the coverage at this time. Codes for marine, tidal, and island polygons have been added, but may be incomplete at this time. In addition, students at the College of the Atlantic attached Maine State Planning Office, Coastal Island Registry Numbers (CIREG) to island polygons. Arcs contain codes describing coastline type, such as MHW, causeway, contour, or river mouth closure line. All 121 coastal quads are available at this time.
Purpose: May be used as a basemap to show coastline, tidal rivers and ponds for mapping purposes. Data at this scale is suitable for use in local planning and detailed studies.

Data, from the U.S. Department of Commerce Bureau of Census 1:100000 TIGER Line Files 1990 were used, in COAST, to represent the offshore limit line. The following information on the origin and accuracy of the offshore limit line was provided by USGS: "According to USGS preliminary policy directive, dated January 6, 1977, the offshore protraction survey data (closure line represented in COAST) was originally shown only on 1:250000 scale topographic/bathymetric maps. In response to additional user requirements the decision was later made to show this data on all 1:100000 and 1:250000 scale maps regardless of the availability of bathymetry (Supplemental Topographic Instruction (STI 80/2/C, March 17, 1980). The offshore protraction surveys were prepared by the Bureau of Land management (BLM) for managing Federal Outer Continental Shelf (OCS) leasing programs. The protraction surveys were plotted by BLM at 1:250000 scale to produce the OCS Official Protraction Diagrams. In October 1982, the responsibility for preparing leasing maps was transferred from BLM to the Minerals Management Service (STI 83-5-C, August 26, 1983). The Information was plotted on 1:100,000 scale maps from copy that was enlarged from the 1:250000 scale graphics. The information on the 100,000 scale maps was provided in digital form to the Census Bureau for their TIGER Line Files. The offshore protraction diagram limit line parallel to the shoreline on the Official Protraction Diagrams is not identified as a territorial limit line or labelled on USGS maps as the three mile or three league line. While this line is located approximately three nautical miles from the shoreline, it is technically the protraction diagram limit line, not the actual three mile limit line. . . .the protraction limit line . . . can only be as accurate as the original source (BLM Official Protraction Diagrams)."
Process Step:

Process Description:
Each MaineGIS 1:24000 base layer represents the automation of a thematic layer from a U.S.Geological Survey (USGS) 7.5 minute series 1:24000 scale quadrangle map. Since the early 1990s, Maine Department of Conservation (MEDOC) has led a multi-agency effort to fund the automation of data to serve a diverse suite of state agency applications in areas that include natural resource management, environmental protection, transportation, and human services. Initially nine base layers were identified for conversion to digital files: coast, contours, otrans, ponds, rivers, roads, streams, towns and wetlands. Automation and quality control, of over 700 U.S.G.S. quadrangles that cover the State of Maine, were coordinated by the Maine Office of Geographic Information Systems (MEGIS). Automation was verified using quality control parameters and procedures outlined in MaineGIS "Data Standards for Maine Geographic Information Systems", March 1990. For MaineGIS base layers, a number of contracted sources were used to scan and vectorize the data from mylar separates or the best available media. Digital files were delivered by contractors in Universal Transverse Mercator (UTM) projection, Zone 19 referenced to the North American Datum of 1927 (NAD27) and in ARC/INFO format, the software standard for Maine's statewide GIS. Quads were digitized at a Root Mean Square (RMS) error not to exceed 0.005 and at a fuzzy tolerance equivalent to 0.002 digitizer inches at the scale of the manuscript map. Map features were digitized within the equivalent of 0.01 in. of the original manuscript. Mylar proof plots of the digitized coverages, with USGS tick marks, neatline and legend, were generated at a pen width of 0.01, and at the original scale, and provided by contractors on delivery of each digitized quad. At MEGIS, proof plots were overlaid on original base maps to check registration, linework quality, and completeness. Features were verified by the following standard of accuracy: 90% of the

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.

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.

At its May, 2004 meeting, the National Historical Publications and Records Commission initiated the GeoArchives records access project by funding a grant to:
1) create standards in order to designate a select set of Maine State Geographic Information System (GIS) records as archival,

2) develop, in partnership with the GeoLibrary, an internet-based GeoArchives system prototype, and implement it for a selected set of archival GIS records, and

3) amend Archives Advisory Board, GeoLibrary, and Information Services Policy Board rules to recognize and enforce the implementation of the new standard(s) and prototype throughout Maine government.
