Qlik sense Extension Geo Analytics Leaflet Mapbox

Qlik sense extension -Geo Maps - Leaflet Mapbox

This Qlik sense Extension Geo Maps Leaflet Mapbox is my first attempt to explore Geo Analytics using leaflet and mapbox. Though Qlik sense provides some built-in capabilities and a separate product for Geo Analytics, I would like to explore the same using some other tools. This is a very primitive extension that just tests the possibility of integration. There are multiple options in map box that can be leveraged to make a sophisticated geo extension. My initial try was with Google Maps but the number of API calls that Google allows were not enough and hence went for mapbox. To access mapbox capabilities through API, this extension uses the open-source leaflet library. The website has lot more examples of advanced geo analytics.

Before you use the extension, complete the following steps.

  1. Create an account in Mapbox
  2. Once the account is created, generate an access token. Typically, you will have a default access token. However, its better to create one for each application. I used the default access for this experiment. But you can customize it, if you are familiar with it.

  3. Now you can see the access token associated with your account in the access token page of your account
    Mapbox - List Access Tokens
  4. Keep the access token handy and you will use it in the extension
  5. Get  a sample data. For this example, I have used the sales sample data from sharecsv.com that contains latitude and longitude

Dimensions and Measures

There are three dimensions and 2 measures available in the extension

The first dimension gives the description of the geo space. If you plot country, then its a country name field. If you plot city then its a city field.

The second and third dimensions are latitude and longitude co-ordinates respectively.

The first measure is the value that will be displayed in the tool tip on click of the data points.

The second measure is optional and it determines the color of the data point. The result must be a color code.
