People keep using the words "plat" and "survey". Are they the same thing?

They're related, and people often use the words loosely.
- Survey: the professional work of measuring and establishing boundaries, plus the signed drawing or report that shows the result.
- Plat: a map. It's often a recorded map that creates lots and streets in a subdivision, and is filed with the county. A drawing of an individual survey is also commonly called a "plat of survey" [1].
A recorded subdivision plat typically shows:
- lot numbers and dimensions,
- street names and widths (rights-of-way),
- easements and building lines,
- monuments and notes [2].
If your deed says "Lot 12, Block 3", it refers to a recorded subdivision plat. A surveyor uses that plat, plus field evidence, to locate your lot on the ground.
