+## Terms
+
+- Reference point: A fixed survey station or control point used as the origin for measurements
+- Baseline: The main survey line between two reference points, along which chainages are measured
+- Chainage: The linear distance measured along the baseline from a fixed starting point
+- Offset: A perpendicular distance measured from the baseline to locate a feature
+- Tie measurement: General term for measurements taken to “tie” features to the baseline, often recorded in a tie table.
+- Detail point: A sub-point or feature (tree, culvert, corner) located by offsets from the baseline
+- Tie table / Offset table: The tabular record of chainages and offsets used to reconstruct the sketch.
+- Tie sketch: The graphical sketch showing how offsets are taken from the baseline to locate features.
+- Plot corners: The boundary-defining points of the parcel. Corners are usually labeled A, B, C, D, … in clockwise sequence around the plot
+- Field book: The official record where chainages, offsets, and sketches are entered during survey work.
