Below follows a description of the MEDRDVD data base. MEDRDVD contains watershed boundaries for most ponds and rivers in Maine, based on USGS 1:24,000 scale quadrangle maps. 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. Preliminary polygon coding was also begun at this time. 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. In 1993 OGIS 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. Some coastal embayment drainages and Water District boundaries have also been coded. 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. Data at this scale is suitable for detailed studies and local planning. Not for use in scales greater than 1:24000.

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.

Standard Order Process: Digital Form: Digital Transfer Information: Format Name: ARCE Format Version Number: ARC Version 9.x 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 Transfer Option: Online Option: Access Instructions: Where file size and Internet access permit, data requests can be made available via File Transfer Protocol (FTP) from the ftp address ftp://ftp.state.me.us/. Digital Form: Digital Transfer Information: Format Name: ESRI Shapefile Format Version Number: ARC Version 9.x 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.
