Description:

Abstract:
HYDRO maps Maine lakes, ponds, rivers, perennial and intermittent streams, and coastline at 1:100,000 scale. Data for this coverage were complied from USGS 1:100,000 scale digital line graph (DLG) files by J.W.Sewall Co. for the Maine Low-Level Radioactive Waste Authority in 1989. The USGS major/minor coding scheme is used in the coverage. Maine's 3-mile marine jurisdiction limit was added by MEGIS staff in 1992 to close the coastal water polygon for shading purposes. Codes have also been added to identify tidal rivers in Maine and Maine Department of Environmental Protection Water Quality Classes. In addition, IF&W's MIDAS lake codes have been added for lakes greater than 10 acres. Please report any MIDAS coding errors to the Maine Office of GIS.
Purpose:
Data for HYDRO were complied from USGS 1:100,000 scale DLG files by J.W.Sewall Co. for the Maine Low-Level Radioactive Waste Authority in 1989. Codes have been added to identify tidal rivers; water quality classification and MIDAS numbers, a unique four digit identification code for lakes.

Other Citation Details:
Digital line graph (DLG) data are digital representations of cartographic information. DLGs of map features are converted to digital form from maps and related sources. Intermediate-scale DLG data are derived from USGS 1:100,000-scale 30- by 60-minute quadrangle maps. If these maps are not available, Bureau of Land Management planimetric maps at a scale of 1:100,000 are used. Intermediate-scale DLGs are sold in five categories: (1) Public Land Survey System; (2) boundaries; (3) transportation; (4) hydrography; and (5) hypsography. All DLG data distributed by the USGS are DLG - Level 3 (DLG-3), which means the data contain a full range of attribute codes, have full topological structuring, and have passed certain quality-control checks. DLGs depict information about geographic features on or near the surface of the Earth, terrain, and political and administrative units. These data were collected as part of the National Mapping Program.

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 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.

Ordering Instructions:
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.
