Publication Date: 19930101 Publication Time: Unknown Title: hydro Geospatial Data Presentation Form: vector digital data Series Information: Series Name: Maine GIS Data Catalog; Maine GIS SDE Server Publication Information: Publication Place: Augusta ME Publisher: Maine Office of Geographic Information Systems (MEGIS) Other Citation Details: 100000 Online Linkage: http://megis.maine.gov/catalog/ Description: Abstract: The representation of the Sheepscot River was obtained by selecting the river arcs from the 1:24k scale representation of streams within the Sheepscot Basin (originally labeled hyd24n), and saving as a separate coverage in ArcInfo. The coverage was then converted to a shapefile. 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.

DLG's 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 DLG's 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. DLG's 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.

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 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.
