more obvious in their geographic context. To visualize the whole study area at once inthis way would not be illustrative, because the high resolution makes the output unclearand confusin g. The result after post processing the ou tput gives us a total amount of 250potential sites for small-scale hydropower stations wit hin Kisoro and Kabale.(a)(b)Figure 5.8 a) Showing raster output containing potential sites for small-scale hydropower(red lines) and b) the same output with contours.5.2.3 VisualizationA basic but illustrative way of visualizing the potential sites derived by the algorithm is todisplay the number of sites per sub-county in a map (see Figure 5.9). It does not displaythe exact location of each site, which would make it too difficult to interpret, but itshows areas presumed to be of most interest for small-scale hydropower prospectors.Figure 5.9 Overview map showing distribution of potential sites per sub-county.52
A more advanced way of presenting the result would be to take more factors of interestinto account. Such factors could be population density and distances between roads andpotential sites, which can be seen in Figure 5.10.Figure 5.10 Overview map showing distribution of potential sites per sub-county. The segments inthe pie chart diagrams represent the proportion of sites within a certain distance from a road. Thesizes of the pie chart represent the number of potential sites in 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 in Figure 5.9 above, thedegree of detail is rather generalized; therefore 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 in Ikumba sub-county. Each red line, regardlessof its length, indicates one potential site for a small-scale hydropower station.53
