[Qgis-user] Binary hillshad raster for sunpower plant

[kajjo Darious]

Hullo QGIS family

I have data about pregnant mothers, those that delivered, pregnancy
outcomes and health facilities they went to and administrative boundaries
of villages. This data was collected using 2-stage sampling like selecting
a village from each subcounty and from villages 30 households were
interviewed. I want to develop catchment areas of these health facilities,
measure distances to these facilities and do hot-spot mapping of pregnancy
outcomes to see where are abortions most, miscarriages and live births.
Which methods and plugins can i use in QGIS?
