- 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.
