If you would like to view your results based on location, you can select a geolocation chart type. You must have location attributes added to your dataset to use geolocation. If your results are placed in the incorrect areas, you might need to regeocode your values. Geocoding or regeocoding is the process of assigning new locations to your geographic data.
This article covers the following sections:
Before you can use geolocation, you need to add your geographic attributes to Columns and your metric to Metrics. If you added your geographic data, but your map is not appearing, BIME might not have recognized your attribute as geographic data.
You can fix this by clicking the Data structure icon (), then selecting the attribute. Click the down arrow next to the attribute name, then select Edit geographic level.
If your values are appearing in incorrect locations, you might need to regeocode your values (see Geocoding values).
The following are the available geolocation charts:
If you select map, circles will appear over each location where there is data. BIME will aggregate overlapping points until you zoom in.
Below is an example of the default map view.
Initially, maps will auto-zoom and center based on the location of data points. You can overwrite this in Chart configuration > Chart, then select the 'manual' position option. The 'manual' option is useful if you want to focus in on your home market or head office.
When you use the map type, you can edit the following options in the Chart configuration menu:
- In Chart, you can
display of results. Results can be shown as colored circles or as a heatmap. If you
select heatmap, you can edit the color range in Chart. Heatmap results will
resemble the image below:
- If you are using the Row Selector, you can assign a color palette to represent the attribute's different values. You can select a new color palette in Colors > row all.
- In Chart, you can change the radius of points, the opacity of circles,
merging options, and the initial map position. You can also change the base layer of
the map. Below is an example of the same map, but with a terrain base layer and zoomed
in to the United States
Instead of representing results by circles, the choropleth chart highlights areas. You can zoom in to view more details on which areas contributed results. The choropleth uses a gradient to show the areas with the highest and lowest results. This geolocation chart is useful if you are interested in a high-level overview, rather than individual details.
If you want to zoom in or zoom out, select an area and the interaction option. After you zoom in, a zoom legend will appear on the left side of your report. For example, the map below is zoomed in to the state level. The zoom legend gives the option to return to the country or world view.
For the choropleth, you can select different projections in Chart configuration > Projections. The different projections will change how your world map is displayed. By default, your chart will be displayed in the Miller projection.
- In Chart, you can choose to show the latitude and longitude lines by checking Display the graticule.
- In Colors, you can select a new gradient style in Color encoding. You can also change the color of the land and the minimum and maximum values.
- In Zoom, you can edit the zoom legend range, color, and visibility.
When you select a geolocation chart, your data is automatically placed. Sometimes, your data can be placed in the wrong location. This can occur if your data contains cities, zip codes, or other values that are used in more than one location. For example, if one of your values is 'Bakersfield', BIME could automatically place your result in the United States. However, if you actually meant Bakersfield in the United Kingdom, you would need to regeocode your value.
- Click the Chart configuration icon on the right side of the Query Builder.
- Select the Geocoding option.
- If you want to view the attribute's values that have not been added to the map, select Not geocoded. If not select All.
- Select the value you want to regeocode.
- In the Geocoded Value textbox, type in the new location. Please enter the
zipcode or city first, then state or country. Alternatively, you can enter the latitude
and longitude values.
- Click Geocode.
Your value will be regeocoded.
