A more advanced way of present<strong>in</strong>g the result would be to take more factors of <strong>in</strong>terest<strong>in</strong>to account. Such factors could be population density and distances between roads andpotential sites, which can be seen <strong>in</strong> Figure 5.10.Figure 5.10 Overview map show<strong>in</strong>g distribution of potential sites per sub-county. The segments <strong>in</strong>the pie chart diagrams represent the proportion of sites with<strong>in</strong> a certa<strong>in</strong> distance from a road. Thesizes of the pie chart represent the number of potential sites <strong>in</strong> the sub-county. The colors of thesub-counties symbolize the variation of population density.This figure helps to decide which areas that have a high population density as well ashigh number of potential sites and their distances to roads. As <strong>in</strong> Figure 5.9 above, thedegree of detail is rather generalized; there<strong>for</strong>e if the exact position is desired, a moredetailed map over a smaller area can be used (see Figure 5.11).Figure 5.11 Geographic position of potential sites <strong>in</strong> Ikumba sub-county. Each red l<strong>in</strong>e, regardlessof its length, <strong>in</strong>dicates one potential site <strong>for</strong> a small-scale hydropower station.53
