Sourhope Field Experiment Site: Topographic Survey

A topographic survey of the Sourhope Field Experiment Site was conducted in the Spring of 2000 by Mick Whelan and Stuart Bradley (University of Stirling). In addition to the various maps generated, the raw data is also available for those who wish to match this information to their own data, or analyse it in more detail.

The downloadable zip file below contains the following information:

  • Explanatory notes and survey details - readmegrd.txt

  • Original survey data (x-y-z co-ordinates) - newsourceall.xls

  • Regular grid for across the site at 25cm intervals, with interpolated altitude values - newgrdxyz.txt

  • A macro which will work out the x-y part of the grid reference as used in the above files for any cells on inputing the Block/Main-plot/Cell(x,y) in the standard programme notation  -  coordconv.xls

A.  Site Level Maps
The following two maps are first draughts of complete topographic survey conducted at the Rigg Foot plot, Sourhope, which give and overall picture of the site's topography. Please note: These contour maps represent interim results - better quality maps including sub-plot boundaries within each treatment can be found in section B below.

Smaller dots indicate individual survey points and will be removed from definitive versions.


B.   Main-plot level Maps
More detailed maps than those given above which show the Sub-plot boundaries and have a 50cm cell grid overlay are held in the Microsoft PowerPoint file given below. If you are unable to view this file please contact the Programme Data Management team.
