I have been familiarising myself with QGIS and the free information Ordnance Survey provide. Though I'm struggling to find further data specific to my needs.

I want to produce a map plotting renewable energy in the UK (or at least operating wind turbines) against locations of operating data centres, preferably on a background of wind speeds.

Are there places where I access this data?

By so far I have seen only these sources:

When you import a shapefile (or zipped shapefile) into QGis is just displays the data using a random color. So you need to style it and select a attribute to colour it in by and how you'd like the values mapped to colours.

The trick with the wind speed data is to read the documentation (boring though that is) - so looking in the included "Wind_attributes.txt" file gives us:


An = Annual SP = Spring SU = Summer AU = Autumn WI = Winter

JA = January FB = February MR = March AP = April MY = May JN = June JL = July AG = August SE = September OC = October NV = November DC = December


80 = 80 metres above sea surface 100 = 100 metres above sea surface


WS = Mean Wind Speed recorded in metres per second (m/s)

PD = Mean Wind Power Density calculated per square metre of rotor swept area

If I choose to use a Graduated style I will get a choice of columns to map. Based on the above list it looks like if I pick an_ws_80m I will be mapping Annual Wind Speed at 80m above sea level.

Pressing the classify button will apply the settings to the map. I find that the map looks better with Jenks Natural Breaks rather than Equal Intervals but your mileage may vary. I have also increased the number of classes.

Finally to make it look a little nicer I removed the black lines by setting the Stroke style to No Pen.

  • That's great thank you! Also, i was wondering is it possible to both graduate AND categorize information when bringing in a .csv?

  • Yes, first set up the categorize or graduated style how you want, then change the style to rule-based. Each category will be automatically converted to a rule. Select a rule and choose "refine selected rules" at the bottom of the style manager. There you have the option to add scales, categories or ranges.
