Layer Name:	DLG Pipes and Transmission Lines

Coverage Name:	UTILITYDLG	

Layer Type:	LINE

Status:		Complete

Geog. Extent:	Islands of Niihau, Kauai, Oahu, Molokai, Lanai, Maui,
		Kahoolawe and Hawaii

Projection:	Universal Trans Mercator, Zone 4 (Meters)

Datum:		NAD 83

Description:	Extracted from the USGS 1983 DLGs for the
		main hawaiian islands.

Description from "Standards for Digital Line Graphs, Part 3 Attribute Coding":

Transmission lines and pipelines are not shown on USGS maps as
continuous transportation features. These features are shown more
for their landmark character. Pipelines in particular are often
shown only where there is a visible scar on the ground. As
explained in section 3.0.5, some features are suppressed for
legibility concerns. Transmission lines and pipelines are often
suppressed for other features, particularly roads. Do not attempt
to connect the dropped portions of these features. Digitize these
features as shown on the map.
