[MUSIC] Hi there. When talking about maps, sometimes the location data you have might be incomplete, or have an error, or may not be recognized by Tableau as a location. So for this lesson, I will show you how to customize your location data to create Tableau maps with geographic data not recognized by Tableau. [MUSIC] Let's begin by opening our Supersore data set, and dragging our City field to our view. Now, although our map does show cities across the United States, as we can see from the bottom right-hand corner of our screen, there are many unknown locations. Sometimes Tableau will not recognize one or more of certain location names in your data. When this happens, those values are marked as unknown in the lower right corner of the view. This often happens because your data values may be spelled incorrectly, or used an abbreviation that Tableau does not recognize. When this happens, you can edit the unknown location names to map to known locations. To edit these unknown locations, let's left-click on this notice. And now we have options to fix our unknown city locations. We can choose to edit our locations and correct the unknown locations, filter date and exclude the special values from our view and calculations, or show data at default position, and show the unknown values as zeroes. Let's click on Edit Locations. In the Edit Locations dialogue box, click on one of the unrecognized cells to match a known location in your unknown data. When you click on an unrecognized cell, a search box appears. As you begin typing in the search box, Tableau generates a list of possible locations. Select a location from the list. Alternatively, you can select Enter a Latitude and Longitude from the drop down menu to manually map the value to a location on the map. Both unrecognized and ambiguous locations can be listed in the Edit Locations dialogue box. You can usually fix ambiguous locations by specifying the country or region, and/or State or Province options in the geographic role section of the Edit Locations dialogue box. Since we have several cities that are ambiguous, let's click on the State/Province drop-down menu. And click on From Field, and choose State as our field. Now Tableau has identified the missing locations. Now if we click on OK, you will notice that we no longer have unknown cities. So far in this course, we have covered what types of geographic data Tableau allows you to use to create maps. How to connect to a different data source that may hold geographic data that you may want to use in your analysis. How to customize your map by changing colors, shapes, and sizes. And how to customize your map background. And create Tableau maps with geographic data not recognized by Tableau. Now, to help refine your skills, please remember to continue to practice everything you are learning. Go back through everything you have learned in this module, and try to explore ways to expand on what you are learning. In the next lesson, we will cover dual layer mapping, and how to overlay maps on one another. See you next time.
