# USGS Visual Identity System
# 
# To reinforce visually who we are and what we do, the USGS uses a visual identity system that provides planning and design solutions for USGS information products. 
# A key component of the visual identity system is the USGS identifier. 
# This identifier is trademarked and must be used in accordance with the rules outlined in the Visual Identity System. 
# Information on who may use the USGS identifier and how to obtain a copy of it is available at Use of the Trademarked USGS Identifier by Non-USGS Organizations.
# https://www.usgs.gov/information-policies-and-instructions/use-trademarked-usgs-identifier-non-usgs-organizations
# 
# For relevant USGS policy on the Visual Identity System, refer to the Survey Manual chapter entitled, “USGS Visual Identity System.”
