Description:
Abstract:
The RR coverage provides a digital representation of the railroad line features mapped on standard 7.5-minute USGS quadrangles.
Purpose:
These data may be used to construct municipal, regional, or statewide base maps.
Supplemental_Information:
Data distribution tile: statewide

Source data is clipped to an area within 1 mile of the New Hampshire state boundary, where the latter is based on the USGS 1:24,000-scale Digital Line Graph data (see GRANIT coverage PB <URL:http://www.granit.sr.unh.edu/cgi-bin/nhsearch?dset=pb/nh>.

Data_Quality_Information:

Attribute_Accuracy:
Attribute_Accuracy_Report:
Arc attributes were digitally derived from the USGS DLG Major/Minor codes, and thus will have comparable accuracy to those source documents.
Logical_Consistency_Report: Arc-node topology exists.
Completeness_Report: Data is complete for the tile.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data were generated from standard USGS 1:24,000/1:25,000-scale Digital Line Graphs, and thus meet National Map Accuracy standards.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The data were generated from standard USGS 1:24,000-1:25,000-scale Digital Line Graphs, and thus meet National Map Accuracy standards.

Source_Contribution:
The DLG files provided the basic coordinate information for the data layer, as well as the fundamental feature codes.
Process_Step:
Process_Description:
The DLG-3 files for the 213 7.5-minute quadrangles in the state were converted to Arc/Info coverages using "DLGARC". Line topology was constructed, and attributes were appended using standard Arc/Info utilities. Each tile was then projected from UTM meters (Zone 18 or 19), NAD27, to NH State Plane feet, NAD83. The individual tiles were then edgematched, allowing for movement of arcs at the quadrangle seams of up to 10 ft. to create the statewide layer.
