Description:
Abstract:
Contains watershed boundaries for most ponds and rivers in Maine, based on USGS 1:24,000 scale topography. Drainage boundaries were determined using the 1:24,000 scale contours and were delineated on mylar copies of these maps by USGS staff in Augusta, ME in 1989. The mylars were digitized by Maine Geological Survey (MGS) in 1990 for the Maine Low-Level Radioactive Waste Authority. In 1993 MEGIS staff added the 1:24,000 coastline to this cover to close the coastal drainage. Divides were delineated on many coastal peninsulas to facilitate the selection of drainages for coastal embayments. Preliminary polygon coding was also begun at this time. At present the USGS's 8-digit Hydrologic Unit Code (HUC) has been added to all polygons.
Extensive additional coding was done by DEP staff to delineate MIDAS numbers for watersheds, river drainages, and correct known errors.
Purpose:
The focus of the original project was to identify "Great Pond" watersheds (ponds greater than 10 acres in size). As a result, drainages containing only streams are not always as finely subdivided as those containing ponds.

Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the correct copy of both data and metadata from the Maine GIS Data Catalog. Updates, corrections, and feedback, incorporated in the Maine GIS database are made in accordance with "Data Standards for Maine Geographic Information Systems", 2002, and coordinated by MEGIS

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 by using the "project" command in ArcInfo. 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 the Maine Office of GIS data libraries in ArcInfo Librarian were re-created 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.
