We can visualize temperature and humidity over the map using the Coordinate Map visualization. Create a new Coordinate Map visualization by going to the Visualize tab and clicking the + icon to create a new visualization, and perform the following steps as shown in the following screenshot:
Figure 10.8: Creating a visualization to view sensor locations over a map
- As in previous visualizations, add a filter for the sensorType: Temperature.
- In the Metrics section, choose Average aggregation on the reading field as done previously.
- Since this is a Coordinate Map, we need to choose the GeoHash grid aggregation and then select the geo_point field that we have in our data. The location is the field to aggregate.
As you can see, it helps in visualizing our data on the map. We can immediately see the average temperature at each site when we hover over a specific location. Focus on the relevant part of the map and save the visualization with the name Temperature over locations.
You can create a similar Coordinate Map visualization for the Humidity sensors.
