Abstract:
RETROART represents road centerlines along arterials designated "Retrograde Arterials" as part of the MEDOT's statewide Access Management program. A retrograde arterial is a mobility arterial where the access-related crash-per-mile rate exceeds the 1999 statewide average for arterials of the same posted speed limit. The MEDOT Access Management program envisions prioritized planning and preservation of Mobility Arterial corridors most at risk of losing capacity, safety, and of decreasing posted speeds, due to increasing development and commuter and visitor pressures. More about the Access Management Program can be found at http://www.state.me.us/mdot/planning-process-programs/access-mngmnt.php . This dataset was created by Maine Department of Transportation using basemap line work (see the MEDOTPUB (ROADS) metadata for more detail). This dataset is designed for use in applications within MEDOT.
Purpose: Designed to be used for planning purposes.

Process Step:
Process Description:
Source centerline coverage created weekly using an Arc/Info macro, taking spatial information from centerline 'basemap' which is updated continuously. Segment identification codes are assigned to facilitate queries via SQL from related Oracle tables. SQL query to Oracle tables returns attributes of each road segment. These attributes are added through a join process.

Detailed Description:
Entity Type:
Entity Type Label: retroart
Entity Type Definition: arc feature class
Entity Type Definition Source: Environmental Systems Research Institute, Inc. (ESRI)
Overview Description:
Entity and Attribute Overview: RETROART attributes are limited to default items.
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 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.
