Buying a building plot in or around Wigtown? See how the ground falls and what constraints apply before you commit, using the Scottish Government LiDAR flown over the area and published on the Scottish Remote Sensing Portal.
Across the Wigtown area (0.65 km² from the OS Open Names extent), open LiDAR covers 100% of the ground. The best survey for most of it is Scotland National LiDAR Programme, flown 2025–2026 on a 0.5 m grid.
That survey is recent (about 0 years old), but anything built or dug since still won't show. The flight date is on every page of the report.
Most of the ground across the area (96% of readings) lies between 7.5 m and 56.7 m above Ordnance Datum, with a median of 34.9 m. The extremes (4.5 m to 61.2 m) can include water surfaces and data edges, so we don't quote them as ground levels.
That makes Wigtown steep ground by Scottish town standards: about a quarter or more of it falls faster than 1 in 10. On slopes like that, the cut-and-fill estimate and the fall across the plot are often the numbers that change a build budget most, so they're worth seeing before an offer.
Tiles from LiDAR for Scotland Phase 3 (flown 2015–2019); LiDAR for Scotland Phase 1 (flown 2011–2012) also overlap the Wigtown extent, but where surveys overlap the report uses the best one, as above.
Fitting a plane through the 10 m levels, the ground across Wigtown falls generally towards the south-east at about 52.7 m per km (roughly 1 in 19). The lowest tenth of the ground lies mostly to the east, and the highest tenth lies mostly to the north-west.
About 9% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 9.6°.
On SEPA's flood maps (medium likelihood), none of the Wigtown extent is inside the river flood extent, 2.3% inside the surface water extent and 0.1% inside the coastal extent. The extent is a rectangle round the town, so it can take in foreshore, sea and open ground. These are indicative national maps, not a flood risk assessment; a plot report gives the figures for your own boundary.
Historic Environment Scotland has 99 listed building records in the extent (31 category B, 68 category C), and 1 scheduled monument and 1 conservation area overlapping it. A plot report lists any that touch or sit near your boundary.
No NatureScot SSSI, SAC, SPA, Ramsar site or National Nature Reserve overlaps the Wigtown extent.
None of the Wigtown extent is within the Coal Authority's Development High Risk Area.
Nearest towns with pages here: Newton Stewart, 11.4 km north, median ground about 5 m lower; Whithorn, 15 km south, median ground about 26 m higher; Gatehouse of Fleet, 16.6 km east, median ground about 18 m lower; Kirkcudbright, 25.7 km east, median ground about 18 m lower.
Sampled every 10 m, the typical slope is 4.2°, and 29% of the area is steeper than 1 in 10. A single plot can be much flatter or steeper than this. Its report works at 0.5 m.

Read from the open LiDAR at a 10 m sample on 2026-10-23; local data checked 2026-10-23. A plot report reads the same data at 0.5 m for your boundary only.
Accuracy. We test Scottish LiDAR against independent survey overlaps and Ordnance Survey levelled trig pillars: heights are ±0.14 m typical on open ground (95% within ±0.28 m). Results by survey phase.
