Today, let’s talk about data maps , which are often used when doing data analysis about geographic locations.
Regarding the tools for making data maps , the author does not specifically emphasize what tools to use, and data maps are not the core function of these tools. Excel can do it, D3 can display it, and even pictures + PS can make the effect you want. So before choosing tools, you should think about what the main purpose you need to use these tools is.
Maybe you just want to display the processed data, you can choose excel; maybe you have all kinds of data, but you don't know data modeling, programming, or data cleaning, or even SQL optimization, you need a FineBI and Tableau are easy-to-use BI tools that can visualize data by dragging and dropping, and can give the most suitable display graphics; maybe you want to use the data map function when making data reports to make a clear display , then you can choose the following finereport reporting tool . ( Finereport is reporting software here , FineBI and Tableau are visual BI tools, and Excel is the most basic data processing tool. It is recommended that you choose tools based on your core needs.)
Therefore, the above tools all have a data map function, but each has differences, such as styles, whether there is a drill analysis function, and whether it can be accurate to longitude and latitude.
I wrote an article before on how to use the data source in excel to make a data map. The map style is very rich, but some places need to be developed. This article will introduce how to use the data map creation function of finereport to improve the force of the data reports of the table cousins .
Finereport has very powerful map functions: basic maps, GIS maps, thermal maps, big data flow maps, etc., and has the following system.
GIS map
At present, the GIS maps supported by finereport include Baidu GIS map, AutoNavi GIS map, and Google GIS map.
Principle: Finereport has built-in interfaces with Baidu Maps and Google Maps. As long as an accurate positioning information data table is built, it will be automatically parsed after uploading and accurately located to the address.
Taking Baidu GIS map as an example, you can use address positioning (xxx street in xxx city) or latitude and longitude positioning (116.390964, 39.920281 ). Generally, latitude and longitude positioning should be more accurate.
Operation process (the figure below shows address positioning)
Upgraded GIS Layers (Geographic Information System)
On the basis of GIS map, combined with bubble chart, pie chart, column chart overlay display, and corresponding data can be displayed. The operation is the same as above.
Area map
point map
Functional upgraded version of GIS map
Functionality mainly means that such a map can be linked with data table drilling. For example, the provincial level can be drilled to the city level, county level, and street level; click to link to the sales report of each region.
Hotspot map
flow map
