Zhang Haiping was very interested in the "Digital Earth" plan proposed by Yang Jie, and also asked a lot of detailed technical details.

Yang Jie also wanted Zhang Haiping to explain in detail.

The digital earth is mainly to digitize the surface of the earth, while aerial photography and aerospace remote sensing are the core of the surface digitization, and the most basic technology is based on the three technologies of global positioning system, geographic information system and remote sensing technology.

Satellites use the Global Positioning System (GPS) to identify targets, and remote sensing technology uses electromagnetic waves to identify and analyze targets on the surface. The integrated GIS software is responsible for the organization, management and analysis of remote sensing data, which are indispensable and interlocking to form the digital earth.

The 3D version of the digital earth Yang Jie uses the lidar and microwave radar carried on the satellite to collect and obtain data such as the height and fluctuation of the earth's surface to establish a digital 3D model.

Such a digital map greatly improves its spatial resolution, its horizontal and vertical accuracy, and has a more accurate ability to identify water bodies.

This is a rare weapon for the military, and with such a digital map, aircraft and missiles can fly close to the ground to evade radar, which is of great military significance.

In addition, digital maps like this can be used for highway planning, outdoor adventure, natural resource exploration, personnel search and rescue, emergency rescue and disaster relief, etc.

With such satellites and technical means, Huaxia has world-class three-dimensional surveying and mapping technology, which is a valuable information coveted by planning, taxation, environmental protection, land, agriculture and other departments, and this is also the core competitiveness of Huaxing Group in the field of civil navigation.

After hearing Yang Jie's detailed explanation, Zhang Haiping said to Yang Jie: "You can get it first, and when you start to officially provide business content, you can pass the military's review, and the military will also give priority to purchasing digital 3D maps from you." ”

With digital maps, Army units can accurately grasp the slope of any section of mountain and the depth of any section of the river. This is a qualitative improvement in the army's field capability, and the air force's aircraft will become more effective and diverse in penetrating defense through ultra-low altitudes.

At the same time, the digital map can provide accurate target information for the army, with a three-dimensional model, the army can know how much oil tank capacity is in a certain place, how many soldiers can be accommodated in a barracks in a certain place, these extremely valuable information can be judged and analyzed through satellites, which in the past through a flat map could not be done, and it is also unimaginable.

With these models, it will be easier for the military to obtain target information, determine the value of the target, determine the effect of the strike, and even use it to set the trajectory, which will multiply the effectiveness and flexibility of the firepower strike.

The digital map can provide terrain matching data for cruise missiles, and after mastering the three-dimensional map, the flight path of cruise missiles will be more tricky, and because of the high-precision grasp of the terrain, the establishment of navigation points is no longer necessary, and cruise missiles will become more strange and more difficult to intercept.

Now Huaxing Group wants to carry out technical layout in this regard, just by providing civilian commercial digital maps can ensure profits, but also can greatly improve the domestic and military digital geographic information database, but also for the military combat system construction has filled a gap, greatly enhance the army, air force and rocket force information combat capabilities.

Huaxing Group Company has been laid out in advance in many aspects, and it is of great help to national defense construction, and Zhang Haiping naturally wants to fully support such a thing.

The year before last, Quantum Networks established a Quantum Map Digital Map Company, and after obtaining the consent of the surveying and mapping management department, it used GPS mapping tools and vehicles to conduct very careful and thorough field surveying and mapping of the whole country, and obtained a very accurate digital map.

Of course, once the detailed geographic data of key institutions, sensitive facilities, and important resources are blocked.

Quantum Digital Map uses very professional surveying and mapping tools to make a very accurate digital base map of the geographic coordinate system for the whole country, even in the field of professional surveying and mapping, it is a core secret and belongs to the country's top secret information.

The longitude is accurate to the minute, the longitude of 1 minute is more than 1800 meters wide, if it is accurate to the second, the width of the longitude of 1 second is only about 30 meters, there is such an accurate base map, coupled with field surveying and mapping, the positioning of a target can even be accurate to the centimeter level.

More than 300 types of geographic information elements have been added to this top-secret digital map, which is the most accurate confidential digital map in China at this stage.

The map has been delivered to the military and the surveying administration, and the military is already using the digital map.

The electronic maps that Quantum Networks can publicly distribute to the outside world are only allowed to overlay up to 17 layers.

This year, Huake Airlines, a joint venture between Huaxing Group and Hongdu Group, provided Quantum Networks with a special surveying and mapping drone with an electric propeller, which is equipped with a high-resolution digital camera plus lidar, microwave radar, and digital thermometer, with a flight time of up to 30 hours, which can basically complete the surveying and mapping of a city in one day, and the efficiency is faster.

The large amount of data obtained can be imported into GIS professional software to obtain a 3D digital map with very high accuracy.

Such a drone with a wingspan of eight meters and a fuselage length of five meters can reach a payload of 400 kg, so it can carry a large number of professional instruments and equipment.

The cost of such a drone is more than 600,000 yuan, and Quantum Digital Map Company has also purchased several drones and divided into several teams to carry out surveying and mapping work at the same time.

At the same time, Quantum Digital Map Company has also begun to open branches in these overseas countries, and has cooperated with local mapping companies to carry out various surveying and mapping work in the local area.

Quantum Digital Maps already offers free versions of digital maps for automobiles and mobile phones, and now has hundreds of millions of users, and the number is growing.

Quantum Digital Map Company is aiming at these commercial places, these commercial places want to appear to be marked out naturally it is paid, in addition to advertising implantation, because it has a large user base, the frequency of use is also very high, so Quantum Digital Map Company will also receive the corresponding advertising to achieve revenue, but ordinary consumers are not aware of Quantum Digital Map Company's profit method.

Now Quantum Digital Map Company has relied on these two businesses to achieve profitability, and now the digital map company has begun to use the data of more than 100 million users to study consumer habits, in fact, the entire Huaxing Group Company is mining data to study its own customers, and this work has been done many years ago.

Now Huaxing Group has done a very good job in the analysis and mining of big data, not only has developed a set of very intelligent analysis software, but also relies on this model for the group company in the company's internal management, production efficiency, so that the enterprise scientific judgment, decision-making, cost saving, reasonable allocation of resources, improve income.

In addition, this big data mining system also makes Huaxing Group more accurate in marketing, advertising, etc., reducing costs and bringing a lot of profits.

The digital earth plan proposed by Yang Jie is certainly not an unprofitable matter, because for the digital earth, the key and constituent foundation is data, and an ordinary reader cannot derive data, and in order to obtain data, the buyer has to pay to buy relevant information.

The higher-level digital earth technology concept relies on large-capacity storage, fast data processing and technical support of broadband information channels to generate a virtual digital earth environment, and users can rely on computers to enter a virtual environment and then carry out related operations.

However, at this stage, the technical level is not yet reached, and Huaxing Group has such technical ideas within the group, and some technologies have been pre-researched.

"Speaking of drone technology, now the rainbow series of drones of Huake Airlines is really very good, and you have made a great product!"

Zhang Haiping said with emotion.
