[Qgis-user] Breaking a territory into zones

[Nicolas Cadieux]

Hi,
It’s difficult to help without knowing how the data is organized (ex number of people are points data, polygon data, 1 points per person vs aggregated data..)

You can search for grouping, cluster analysis, heat map, voronoi polygons, concave hull.

Once you have polygons you will need to split vector features you create with your current border.  Google join, split, merge vector data. Always add QGIS to get more precise google returns.

I am tasked with finding a way to analyze the data and build "zones" within a territory based on the data with a street line center file.  I have searched for building zones, districts, territories, heatmaps, spatial statistics, voting districts, etc. I found some information relating to ESRI Business Analyst, but that was specific to ArcMap and did not point me in a related direction.

> Centerline File from the State GIS Office
> US Census Block Level data from 2010
> Various boundary files from the State GIS Office
> What I am trying to do is break an territory up into 5 zones.  Each zone should have an equal number of residents.  Zone borders are limited to the edges of the territory.  Within the territory, zone borders should follow the nearest street centerline.
