Where did the Adams onis treaty set boundaries between spanish Texas and Louisiana?

The Adams-Onís Treaty, signed in 1819, established boundaries between Spanish Texas and the United States, specifically defining the boundary between Spanish territories and the newly acquired U.S. lands from the Louisiana Purchase. The treaty set the Sabine River as the eastern boundary of Texas and established a boundary line that extended to the Rocky Mountains, effectively ceding Florida to the U.S. and clarifying the limits of Spanish and American territories.
