Introduction to Map - Longitude/Latitude

If your data contains longitude and latitude information, then you can quickly visualize the data geographically with one of the Map types called ‘Map — Long / Lat’ in Exploratory.

Sample Data

We'll use this US Hospital Rating data. You can download it from this page.

In this data, each row represents each hospital and it has the rating score (1 to 5, 5 is the best) based on the patient survey along with the hospital information including the location related information.

1. Create a Map with Longitude / Latitude

Let’s say we want to visualize where all the hospitals are on Map.

Select 'Map - Long / Lat' and assign the longitude and the latitude columns.

2. Use Color and Configure

We can use Color to visualize the hospital rating score by assigning 'Hospital Survey Star Rating' column to the Color.

You can change the color palette from the Color & Group configuration dialog.

Here, I have changed the Color Palette to 'Red-Yellow-Green' and also the Opacity to 0.7.

3. Use Label to Show the Label Text

Currently, when you move the mouse over on one of the dot you can see the rating score in the pop-up box at the right hand side top.

We can show which hospital each dot represents by using the Label.

Select the 'Hospital Name' column to the Label

Also, click on the 'Set as Title' so that the hospital name will be shown as the Title in the pop-up box.

4. Change Map Style

You can change the map style if you like. The default is 'Light Gray', but for example, we can change it to 'Dark'.
