Tableau map options let you control which elements of the map are displayed. In this video, learn how to add and remove map layers.
- [Instructor] After you create a map in Tableau, you can change its appearance and the data layers that it displays. I'll demonstrate how to perform both of those tasks in this movie. My sample file is 12_02 MapLayers and you can find it in the Chapter Twelve folder of your exercise files collection. In this workbook, I have sales data and it's broken down by Zip Code. Everywhere there's a dot on the map, it represents a Zip Code from which there was a sale. This map is fairly light, you see it has light colors and light background. To change that, I can go to the Map Menu, point to Background Maps and select Light, Normal or Dark. The other options - Streets, Outdoors, Satellite, Offline and None, are used less often and I encourage you to experiment with them. So we currently have Light; if I switch it to Normal, you see that everything is made a little bit more bold and the water especially is darker. If I go to Map again, point to Background maps and click Dark, then essentially the color scheme is reversed, where I have dark colors for land and light for water. I'll go ahead and switch back to my first option, which was Light, so Background Maps and Light. So those are the basic ways that you can change your map, you can also use Map Layers and those contain interesting data elements that you can get from public sources. So if I got to the Map menu again and click Map Layers, then you see over on the left that the Map Layers task pane has appeared. I can change the background here, by clicking at the style control, or I can go down to the Map Layers area and select what I want to display. The basic Map Layers I currently have displayed are Base and Land Cover and you can see there are other elements available below. So, for example, you have Country and Region Borders and you can tell Tableau how you want those to be displayed. If you're working with phone data, you can also do Area Code Boundaries, or if you're working with cities, US Metro Boundaries. I'll go ahead and check that box so you can see what it looks. In the desert Southwest, you'll notice that the Metro Areas are much larger than they are in the Eastern United States. I'll go ahead and turn off US Metro Boundaries again and I'll look down below that at the Data Layer. So we currently have no Data Layer applied, but if I click the Layer Controls down arrow, you'll see that we have a lot of different options - and this is all data from public sources. So you have US Population, Number of US Households, Occupations, and so on. Let's say that I want to overlay my map with Per Capita Income. That would give me an idea about how well-off my customers are. So if I go under US Occupations and click Per Capita Income, I'll see those broken down, in this case at the State level, and the color scheme here for 2018 goes from 12,400 to 28,000, and so on. If I want to change from the State level, I can click the By: controls down arrow, and here I have County, Zip Code and Census Tract. In this case I'll click County and you can see how that is broken down. I encourage you to experiment with the Data Layers and the Appearance controls that are available to you. Tableau Maps are extremely powerful and you can get a lot of great insight out of them.
