- Choose an appropriate color scheme for a choropleth map
- Create appropriate legend for classification scheme and map type
- Implement appropriate classification method for population data
- Utilize proportional or graduated symbols
- Create effective thematic picture symbols
- Work with 3 data frames
- Compile map in accordance with cartographic design principles
Working with three data frames on one "sheet" was a challenge because these maps had a lot of information to communicate. If I had the option, I would deliver this project to my customer as a digital map so that they could zoom in and out as required, instead of trying to get so much information on one sheet of paper. Of course, I could always provide a much larger sheet of paper to my customer.
We looked at Wine Consumption across Europe and then added two more maps that showed Wine Consumption for Females and Males; a total of three maps using European 2013 Census Data. Though the Wine data was from the Wine Institute (www.wineinstitue.org) and is from 2012.
I examined my data and went through each classification scheme and determined that the Quantile method suited my data best. The data was unipolar and sequential and with the Quantile method I ensured each class had data. I also had to Normalize the data for Population so that we could compare the data across Europe more evenly. I experimented with Graduated Symbols and Proportional Symbols--that was fun. With the Proportional Symbols, there appeared to be more overlap and I just could not get them to look very good. I even tried using a "Picture Marker" and adjusting the size:
Nice wine bottle right? If only it had looked as nice on my map. So, in the end, after much experimentation, I decided to use the Graduated Symbols. I think this looks better and at least I picked a color that reminds us of grapes. Hope you like it!
