Once you’ve overlaid the data you want on your map and assigned labels to your data points or polygons, you need to export the image as a JPEG.
First, situate your map in the frame as you would like it to appear in your final image.
Then, click on the “New Print Composer” icon in the toolbar
You’ll be prompted to enter a title – name your map something that clearly identifies it.
You’ll next be faced with an empty screen:
Click on the “add new map” tool in the left-hand sidebar
Then, drag as large a rectangle as possible over the blank canvas. Your map should appear.
You can add additional information to this map. For instance, a legend explaining the color values in your choropleth map.
Click the “add new legend” button, and drag a rectangle where you would like your legend to be.
After you’ve added your elements, go to the composer menu>export as image
Save your image as a jpeg file, and upload to the course blog, with your commentary.
