The remote sensed lineaments were analyzed for spatial density, frequency, orientation, relative entropy and angular atypicality using a computer program developed by the research team. 

The results were presented as tables, histograms and rose diagrams for the whole of the study area and for each specified cell of a grid dividing the island into ten sub areas.

Rose diagrams were generated by depicting the directional frequency or the length of linear features per directional class, each of which had an interval of 10⁰ .
This allowed the analyst to identify the main trends.

The other two properties measured, relative entropy and angular atypicality are related to the spatial distribution of the data and are useful in determining whether the lineaments are aligned to a regional pattern or are random in their distribution. This is important when trying to assess whether groundwater flow is along preferred pathways defined by major tectonic features or whether a high yield is related to the interconnectedness of a number of randomly orientated fractures. 

Rose diagrams of lineament frequency for the whole area (top left), the 10 sub areas defined as shown above, and of the mapped faults (bottom left). The radii of the circles for the sub areas correspond to 12 lineaments, the radius of the total area to 36, while the radius of the rose diagram for the mapped faults to 13 faults.
