A compromise does not satisfy either. To illustrate the system application, a rapid assessment of environmental pollution and public health in the Manila National Capital Region, based on a demo size sample of data is presented below. The policy dialogue is focused on linking public health and disease patterns in an urban area to environmental factors, with the goal of improving the health status of the population, in particular of the poor. The analysis is performed by municipality and it relies upon existing data. Buttons in the toolbar allow back and forth navigation through the charts while simultaneously highlighting the respective municipality both on map and in the data table.
Weights can also be the results of expert advice or a consensus of experts.
Figure 3 shows a tiling of the map and data table with a different set of cards illustrating the result of the multi-attribute evaluation. The stacked cards can be browsed to examine the relative strengths and weaknesses of each municipality relative to all the other municipalities in the region. The green color signals a relative strength, i.e. higher than average for a positive or desirable feature, or lower than average for a negative or undesirable feature. The red color works the opposite way. For example, in Figure 3, Quezon ranks 10 of 18 municipalities, the reason being the higher than average maternal death rate which upsets the lower than average infant mortality.
