How to make data flow and let data embrace data

Mobile data: You can turn on 5G or 4G through the mobile phone home screen, set up a cellular mobile data on

There should be. It's just not showing up on your phone. If you want to look, it depends on what kind of phone you are, and the settings are slightly different. But in general, find the traffic settings and turn on the display.

It shows how much traffic is still used per day for 4G.

Brother, have you bought a SIM card? I didn't buy your phone, it's a half-baked phone. And 3g

4G is outdated.

One is to see if your mobile phone supports 4G, if it does, you will go to the business hall to handle 4G** business.

Go to pieces... It's easy. Draw such a line with a pen. Then set the brush to a certain size. You can set the color yourself. Then look at the path, click on the path, right-click, stroke the path, and tick the mold to press. ok。

The dynamic monitoring system of ecological environment in the Tarim River Basin is composed of four operational application subsystems, each subsystem module completes specific tasks, and the subsystems are associated with each other through networks and databases. Therefore, the flow of data is the basis for ensuring the normal operation of each subsystem, and the data relationship between each subsystem is shown in Figure 3 3.

Fig.3 Data flow diagram of the 3 subsystem.

Before the operation of the system, a large amount of basic data is required, including basic topographic maps of various scales, thematic maps such as multi-period or simple history of land covering, sandy desertification, salinization, vegetation coverage, vegetation growth, etc., and attribute data such as socio-economy, water resources, and hydrology. The data management and database subsystem is also responsible for the management of these data and other achievement data, including backup, recovery, optimization, etc., and can convert and export all kinds of basic data and the achievement data generated by other subsystems to facilitate the distribution and use of data.

The remote sensing monitoring subsystem processes and extracts information from the original remote sensing image data, and calls the corresponding historical maps and knowledge base systems in the comprehensive database as a reference to extract various ecological thematic results of the current situation.

The ecological professional analysis subsystem is an ecological analysis application system based on GIS, which extracts multi-period historical and current situation maps from the comprehensive database, conducts land use status and trend analysis, sandy desertification, salinization, vegetation growth and other early warning analysis, and reflects the analysis results in various forms such as charts and tables, and stores the analysis results in the comprehensive database for viewing by relevant business offices.

All the basic data and achievement data stored in the comprehensive database can be released through the business processing and information service subsystem, and each department can view the corresponding analysis results according to the agreed functions, and at the same time, the relevant basic information of the system operation will be continuously entered into the large database through the business processing and information service subsystem, so as to form an operational ecological remote sensing monitoring and auxiliary decision support system.
