Latitude-Longitude Map (Local)
Latitude-Longitude Map (Local)
Latitude-Longitude Map (Local) is largely consistent in display format with the Aggregated Data Map. The difference lies in the pre-processing of data. The Aggregated Data Map uses summarized data for display, while the Latitude-Longitude Map uses detailed (non-aggregated) data.
If your data consists of latitude-longitude coordinates, it's recommended to use the non-aggregated Latitude-Longitude Map.
- Compared to Aggregated Data Map: Whether to use aggregated data.
- Compared to Region Map: It does not consider administrative boundaries. All mapping is based on latitude and longitude coordinates on the map.
- Even if the data type is a place name, it will eventually be converted to latitude and longitude before being mapped.
- Latitude-longitude maps do not support region drill-down.

In the chart style configuration panel, under Region Selection, choose the map data.
Data Configuration
Data Type
| Data Type | Explanation | Configuration |
|---|---|---|
| Name | Administrative region name, e.g., Shanghai | Scatter/Bubble: Row dimension place [Geographic Name] + [Extra Info] Line (Flow): Row dimension place [Source Name] + [Target Name] + [Extra Info] |
| Longitude & Latitude (Separate) | Separate latitude and longitude, e.g., Longitude: 121.47, Latitude: 31.23 | Scatter/Bubble: Row dimension place [Longitude] + [Latitude] + [Extra Info] Line (Flow): Row dimension place [Source Long] + [Source Lat] + [Target Long] + [Target Lat] + [Extra Info] |
| Longitude & Latitude (Combined) | Combined latitude and longitude: e.g., 121.47,31.23 | Scatter/Bubble: Row dimension place [Longitude,Latitude] + [Extra Info] Line (Flow): Row dimension place [Source Long,Source Lat] + [Target Long,Target Lat] + [Extra Info] |
Why Can Names Be Used for Latitude-Longitude Mapping?
Q: For latitude-longitude mapping, there is a Name option in the data configuration?
A: We have a built-in dictionary of Chinese city latitude-longitude coordinates, making it convenient to use the latitude-longitude map even when only city names are available. Using city names for data mapping requires manually aggregating the data.
Display Type
After selecting the data type, configure the data according to the requirements.
For example, if the data type is selected as Name and the display type is selected as Line (Flow), then the dimension configuration requires row dimensions configured as [Source Name] + [Target Name].
