On Google Satellite Imagery, I've created a layer with objects marking houses in a 1 km proximity to large streets in a rural setting using QGIS with the Openlayers Plugin. I would like to identify the top 10 most densly populated hotspots (most houses within a 1km circle) along app. 100 km accumulated street.
I am sure there is already much Information about such task on the web, it would already be very helpful to give me the right vocabulary for what I am trying to do to be able to do my own research.
Backround Information: My Task is to identify high demand spots for water in an underserved area in Western Africa. There is x number of water kiosks installed, connected by roads with an average distance of about 20km from one another. We would like to set up small water selling Points along these roads and therefore need to find suitable Locations which as many People as possible can reach by foot (i.e. 1 km max. distance).
