Introduction to Maps

In data analysis scenarios, when it is necessary to display data based on geographical locations, the use of map functionality is often required. For example, in the following scenarios, using maps for presentation can express data information more intuitively and efficiently.

• Path of Typhoon Yanyan and affected provinces
• New round of strong wind and cooling weather affecting Northeast and North China regions of China
• National population density distribution
• Transport routes during the Spring Festival travel rush
• Distribution map of animals in China

Of course, not all data related to geographical information requires map display; the use of maps needs to be determined based on business requirements.

Overview

HENGSHI SENSE provides powerful map functionality. It mainly includes:

• Two different types of map charts: Simple Maps and Layered Maps.
• Multiple geographical layers: Label Map, Area Map, Hexagon Map, Heat Map, Scatter Map, Grid Map, Cluster Map, Fly Line Map, Trajectory Map, and supports layer superposition.
• Multiple positioning modes: Location Mode and Latitude/Longitude Mode.
• Multiple GIS map display forms: Baidu, Gaode, etc.
• Map zoom functionality.
• Map drill-down functionality.

Map Styles

Below are the commonly used map styles in HENGSHI SENSE and a brief introduction.

Map Style	Description
Label Map	The Label Map displays label data on the map, commonly used for annotating map data information, often used in conjunction with other layers.
Area Map	The Area Map fills the geographical area on the map and displays data.
Heat Map	The Heat Map displays trends in the visual dataset on the map, such as population density.
Scatter Map	The Scatter Map uses points to mark data information on geographical locations on the map, commonly used to represent the distribution of numerical values in various regions.
Fly Line Map	The Fly Line Map connects the starting and ending positions on the map, commonly used for analyzing the flow of things.
Trajectory Map	The Trajectory Map connects the various points of an object's movement on the map, forming the object's movement trajectory, commonly used for analyzing the movement trajectory or trend of objects.
Macro-Region Map	The Macro-Region Map divides geographical locations into various macro-regions and then conducts data analysis, such as sales in the North China region and sales in the Northeast China region.
GIS Map	Uses Baidu, Gaode, etc. GIS maps to display data information, making data analysis more intuitive.
