Setting up the GIS
To ensure that the dataset is used as designed, follow the proceedings steps to set-up the map:
a) Make sure the required data layers are present. For the summary map, the following GIS layer should be present:
- Leakage_summary
For the detailed map, the following GIS layer should be present:
- Leakage
b) Import the data layers into the GIS software by importing the ArcGIS layer files (named as above). Layer files ensure that the colour and layout of the layers appear as recommended by BGS. For other GIS packages, import the layers manually. A .CSV file is provided with the recommended legend colours.
If you need support setting up the GIS, please contact digitaldata@bgs.ac.uk. The GIS should appear as shown in Figure 1 or 2 (for ArcGIS users).
Using the data
Pan to a location of interest and view each dataset sequentially, following the flow charts shown in Figure 3.
Explanation of sub-layers
Explanations of the sub-layer descriptions for the ‘leakage’ summary map are provided in Table 1. Explanations of the descriptions in the compress, swell, collapse, runsand, landslide and soluble sub-layers are provided in Tables 2 to 7 below.
