Description

Abstract

INDEX24 contains 1:24,000 scale neatlines for USGS 7.5 minute quadrangle maps covering Maine. The index was originally generated by MEGIS staff using the known coordinates for the corners of the USGS 7.5 minute map series. The items NAME and TILE-NAME carry the MEGIS library tile name in title case and lower case. Names are identical in most cases to the USGS official name for each 1:24000 scale quadrangle. Z names, for areas of Maine where data but no USGS quadrangle names exist, are also included. INDEX24 is the coverage 24KINDEX renamed and projected to NAD83.

Use Constraints

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. The Maine Office of Geographic Information Systems (MEGIS) provides notice of updates and corrections directly to the Maine GIS Technical Group and Maine GIS Users, through the MEGISTECH and MEGISUSER list servers. To subscribe please contact MeGIS through the Maine Office of Information Technology (OIT) Customer Support Center (CSC) at (207) 624-7700. To request data correction in, or provide updates to Maine GIS data, please use the contact information contained in the metadata. 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 in consultation with the Maine GIS Executive Council.

Attribute Accuracy

Attribute Accuracy Report

The items NAME and TILE-NAME carry the MEGIS library tile name in title case and lower case. Names are identical in most cases to the USGS official name for each 1:24000 scale quadrangle. Z names, for areas of Maine where data but no USGS quadrangle names exist, are also included. Attribute accuracy was tested by manual comparison to the source with hard copy printouts and/or symbolized display of digital files. Please report errors to the Maine Office of GIS.

Process Step

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.

Overview Description

Entity and Attribute Overview

The items NAME and TILE-NAME carry the Maine GIS library tile name in title case and lower case. Names are identical in most cases to the USGS official name for each 1:24000 scale quadrangle. Z names, for areas of Maine where data but no USGS quadrangle names exist, are also included.

Entity and Attribute Detail Citation

The ArcView shapefile and ArcGIS geodatabase formats, commonly used for Maine GIS data, carry default identifiers and attributes that are software generated and/or important for internal recordkeeping. These are listed here to avoid repetition for every layer, and may not be repeated in the attribute descriptions and definitions of each layer. Common software generated identifiers and attributes in Maine GIS data include: FID (feature identifier), Shape (feature geometry), OBJECTID and SHAPE_lengt. In addition, most GIS formats will carry fields for PERIMETER, AREA and/or LENGTH according to feature geometry. These fields are typically available by default, with the units based on coordinate system or projection units of GIS data. Most GIS software packages also provide a means to calculate these values. It is important to test any columns containing PERIMETER, AREA or LENGTH values before using them for analysis purposes. These important values can be carried from format to format and become out-dated. Verify that the values are correct. Also, in your GIS software, please view the properties of data layers for the map units used to calculate these fields, and for the units set for display purposes.

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.
