An archaeological trial excavation, geophysical and topographic survey was undertaken by the Inner Forth Landscape Initiative, with local volunteers, and AOC Archaeology Group in Zetland Park, Grangemouth. The excavations and geophysical survey focussed on the 17th century Orchard of the park, the site of a medieval Grange of which an enclosing bank and ditch survives as a slight earthwork monument. More recent structures of the park were also recorded by the laser scanning and photogrammetric recording of the war memorial and fountain within Zetland Park.

1020501	RECORDING	TRIAL TRENCH	An archaeological trial excavation, geophysical and topographic survey was undertaken by the Inner Forth Landscape Initiative, with local volunteers, and AOC Archaeology Group in Zetland Park, Grangemouth. The excavations investigated the putative medieval monastic grange. Trench 1 demonstrated the existence of an earthen bank and ditch enclosing the site. Trench 2 was excavated across the a dogleg in the upstanding earthworks and, while not conclusive, the excavation supported this being the entrance into the enclosed grange. Three small trenches were excavated within the enclosed grange, these demonstrated deep deposits of relict cultivation soils that possibly derived, in part, from the sites’ later use as an orchard. The ceramic assemblage collected during the excavations included several late medieval to postmedieval sherds which may relate to the later history of the grange. [...]	20 May 2016
1020505	RECORDING	LASER SCANNING	The measured survey of the war memorial was undertaken using a Faro Focus 3D laser scanner. The Focus 3D scanner is a phase comparison system, capable of full dome scanning at ranges of c.0.5m to 50m, at resolutions of up to 92 lines per degree. Scanning was undertaken at the war memorial using resolutions yielding a typical point-cloud resolution of between 6.136mm at 10m from the instrument. Overlapping stations mean that some of the site was scanned at a greater resolution. The survey was controlled using spherical targets, located using a Trimble S6 total station with site control provided by a Trimble R6 GPS using the “vrs now” service. The laser scan data was registered in Trimble Realworks v.10.0. Orthoimages of the pointcloud were produced using Pointools View 1.8 Pro. The fountain was surveyed by volunteers using photography. Over 300 photographs were aligned, transformed into a pointcloud and then meshed using Agisoft PhotoScan v.1.2.4. Renders of the resulting model were created using Blender v.2.70. [...]	20 May 2016
