🔍 Key Concepts

• National Geospatial-Intelligence Agency (NGA) role in producing charts • Difference between U.S. federal agencies that chart U.S. states vs. territories vs. foreign coasts • Which areas are normally charted by foreign hydrographic offices instead of NGA

💭 Think About

• First, decide whether NGA mainly produces charts for U.S. coastal waters, foreign coasts, or both. How does that compare with NOAA’s role? • Look at each choice and ask: is this area a U.S. state, U.S. territory, or a foreign country, and which agency would most likely be responsible for its standard nautical charts? • For any areas that are not independent countries, think about whether another U.S. agency might be the primary charting authority instead of NGA.

✅ Before You Answer

• Identify which organization is primarily responsible for civilian nautical charts of U.S. coastal waters (states and territories). • Identify whether NGA is better known for worldwide / foreign coverage or for domestic U.S. coastal charting. • Before picking an option, eliminate any choices that would more logically fall under another country’s hydrographic office or NOAA rather than NGA.
