Overview
Application Scenario
The combination map allows you to use the area map, point map, and flow map in combination, displaying areas, points, and data flow on the same map.
The combination map is suitable for displaying data flows such as investment attraction routes and population migration.

1. GIS Layer Setting
Select Type, select China as Map Border/Point, and set GIS Layer to Dark Blue in Custom.
Data Binding
1. Area Map
In this example, you need to set the area name of the bound data to End Area Name to display the end area Nanyang City in the form of an area map. Because we have selected China as Map Border, Nanyang City cannot automatically be matched to Henan, so you need to customize a matching relationship. The following figure shows the specific setting.
2. Point Map
The point map needs to display the data of each start area. When binding data, select Lat/Long as Geographic Info, as shown in the following figure.
3. Flow Map
When binding data, select Lat/Long as Geographic Info, as shown in the following figure.
