The worksheet GWabs_org is populated by the data provider.
Notes on the use of columns:
- The XY-position of the NGR will be adopted as the XY-coordinate of the point location for this borehole. Thaking this position over the actual NGR-coordinate will ensures that the interpolation from gridcell to OBH - using the closest distance method - will be in line with the way that the model has been set up.
- The NGR-coordinates are typically displayed in the tooltip.
- The OSreference will be used for the unique identifier of each borehole. It is recommended, but not required, to convert the gridcell position to Osreference. In any case, please document properly what coordinate has been used for this purpose.

The worksheet OBH_org is populated by the data provider.
Notes on the use of columns:
- The XY-position of the grid cell will be adopted as the XY-coordinate of the point location for this borehole. Taking this position over the actual NGR-coordinate will ensures that the interpolation from gridcell to OBH - using the closest distance method - will be in line with the way that the model has been set up.
Note the difference with column usage for the GW abstraction points. - The NGR-coordinates are typically displayed in the tooltip.
- The OSreference will be used for the unique identifier of each borehole. It is recommended, but not required, to convert the gridcell position to Osreference. In any case, please document properly what coordinate has been used for this purpose.
The following steps should be conducted to prepare and verify the data provided:
- ensure that the OSreference column is populated (how to) as this column will provide the key for unique identification
- ensure that the NGR-coordinates are given in kilometers as this determines
