Contours, spot levels and slope for a plot anywhere in Clackmannanshire that the national LiDAR covers. Draw your boundary and see the ground in minutes.
Published Scottish LiDAR covers all of Clackmannanshire. The best survey available here is LiDAR for Scotland Phase 5, flown 2021 on a 0.5 m grid. It covers 78.1% of the area.
The rest is covered by LiDAR for Scotland Phase 4 (2020, 5.5%); LiDAR for Scotland Phase 2 (DTM only) (2012–2014, 13.8%); LiDAR for Scotland Phase 1 (2011–2012, 2.5%). A report always uses the best survey for your boundary and says which one.
Of the 5 towns we have pages for here, Alva sits lowest (median ground about 15.2 m above Ordnance Datum) and Dollar highest (about 57.8 m).
Dollar has the most ground steeper than 1 in 10 (52.4% of its area), Alva the least (21.1%). Plots a street apart can still differ a lot.

Shares are of the council's land area inside published DTM tiles on the Scottish Remote Sensing Portal, taking the best survey where they overlap (the same order reports use). Accuracy figures are from our own tests; see results by survey phase.
Each page shows the LiDAR coverage, ground levels, slope and mapped constraints for the town.

0.5 m contours and spot levels across your boundary, slope and the fall from side to side, cut and fill for a level platform, mapped constraints with sources, and DXF files for CAD.
It depends on what your designer or the planning authority asks for. The report gives ground levels and contours for the whole plot. If walls, drains, trees or boundary features need measuring on site, that's a job for a land surveyor.
