This page describes a use case for implementing a combo overlay.
Use Case Description
In an area, the locations for social and normal housing are known. Where does severe rainfall (50cm or higher) have impact on social and normal housing?
For this we need to create two average grid overlays, one for social housing and one for normal housing, by selecting the respective category wieght attributes; SOCIAL_CATEGORY_WEIGHT and NORMAL_CATEGORY_WEIGHT. Give each overlay a cell averaging distance of 30m. We also need to add a rainfall overlay to have as a 'filter' over the combination of the other two overlays.
