EIU QGIS Workshop

Let's work with some basic symbology:

1. Police Stations (single symbol)

Let's try symbolizing the police stations with a Sheriff's star.
  • First, select a "Font Marker"
  • For font, select "GSI Map Symbol"
  • Select the symbol that looks kinda like a Sheriff's star

2. Neighborhoods

Next, we'll make the neighborhoods pop out a bit more. QGIS has some good options here:

  • For symbol, "select gradient fill"
  • For color ramp, "select random"
  • Alternatively, create a custom ramp and choose your own hue, saturation and value ranges.

I've chosen muted reds/browns:

nbr_category

  • Then,classify by neighborhood name
  • For more effects, click the "Draw effects" button.

Here's an example using "Inner glow" and "source":

sample layer

Play around a bit, and come up with a style you like.

3. Crime (choropleth)

QGIS also has standard options for classifying data and constructing choropleth maps.  Try this out yourself - see if you can show neighborhood crime counts from the previous section using a graduated color scheme.

In the next section, we'll use blending modes in QGIS to create a bivariate choropleth map.
