# Introduction to Maps

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

* The path of Typhoon In-Fa and the affected provinces
* The impact of a new round of strong winds and temperature drops on Northeast and North China
* National population density distribution
* Transportation routes during the Spring Festival travel season
* Distribution map of animals in China

Of course, not all data related to geographic information needs to be displayed on a map. The use of maps should be determined according to business requirements.

## Overview

HENGSHI SENSE provides powerful mapping capabilities, mainly including:

* Two different types of map charts: Simple Map and Layered Map.
* Multiple geographic layers: Label Map, Area Map, Hexbin Map, Heatmap, Scatter Map, Grid Map, Cluster Map, Flow Map, and Trajectory Map, with support for layer overlay.
* Multiple positioning modes: Place Mode and Latitude/Longitude Mode.
* Various GIS map display forms such as Baidu and Gaode.
* Map zooming functionality.
* Map drill-down functionality.

## Map Styles

Below are the commonly used map styles in HENGSHI SENSE along with brief introductions.

|Map Style|Description|
|----|----|
|[Label Map](map-type.md#标签图)| The label map displays label data on the map, commonly used for annotating map data information, often in combination with other layers.|
|[Area Map](map-type.md#区域图)| The area map fills the corresponding geographic area on the map and displays data.|
|[Heat Map](map-type.md#热力图)| The heat map visualizes trends in the dataset on the map, such as population density.|
|[Scatter Map](map-type.md#散点图)| The scatter map uses points to mark data information at geographic locations on the map, commonly used to represent the value distribution across regions.|
|[Flow Line Map](map-type.md#飞线图)| The flow line map connects the starting and ending locations on the map, commonly used for analyzing the flow of objects or logistics.|
|[Trajectory Map](map-type.md#轨迹图)| The trajectory map connects various points of an object's movement on the map, forming a movement trajectory, and is often used to analyze movement paths or trends.|
|[Polygon Area Map](map-type.md#多边形区域图)| The polygon area map uses GeoJSON to draw the map.|
|[Region Map](map-geographic-role.md#大区地图)| The region map divides geographic locations into different regions for data analysis, such as sales performance in North China and Northeast China.|
|[GIS Map](gis.md)| Uses GIS maps from Baidu, Gaode, etc., to display data information, making data analysis more intuitive.|
