I started to write this article when I hadn't studied in the graduate school, but it hasn't been completed yet. This time I still sent it out to add some updates.
Sorry to cheat you in with the title, the author is just a scum that has not really stepped into the life of a graduate student, the following content is just some of my cranky words after I was inspired by some big guys, if you waste your time I'm sorry, please forgive me.
First of all, it should be explained that the GIS I will discuss here is very narrow, even my own definition. . . Fear of being beaten. . The reason is very simple. My undergraduate miscellaneous teaching method once puzzled me very much. Remote sensing and surveying should be completely independent from the geographic information system. Whether it is knowledge system, methodology or market demand, they are completely incompatible. And compared to GIS is also much more mature. At the same time, traditional geosciences, environment, planning, etc. should not be included in the use of GIS at all. Because that is just a manifestation of the informationization of these specialties, their core still lies in their respective professional knowledge and logic, and GIS is nothing more than an office-like application software. What can students do if they only operate application software but do not understand the corresponding professional knowledge? Professional knowledge and literacy have to be accumulated over a long period of time, but application software is not required, and college training can be employed (no academic discrimination, state the market, and avoid confused students from choosing the wrong direction and going astray). . . I will not list them one by one. All in all, my GIS is more focused on the "information system" itself, at least not in other disciplines, although it seems that GIS is running out. . In fact, I also agree to simply abolish GIS and split it into specific research directions in different disciplines. This seems a lot more reasonable. It is not necessary for undergraduates to set up such a misleading major, and it is not too late for graduate students.
PS (It is best not to have graduate students, each belongs to its own family, and its responsibilities are clearly defined) (The information system part naturally belongs to the computer) (Interdisciplinary is an innovation at the beginning, but if it is relatively mature, if it still cannot clear its internal division of labor It ’s just a hooligan. In fact, the market is much clearer than the school ... This is the problem)
Since we are only talking about information systems, we will analyze it with the earliest and most influential ArcGIS. After Tomlinson, the father of GIS in the 1960s, advocated the use of computers for spatial analysis, the leadership established the leadership role in the process of CGIS (the author went back to the book to write, embarrassing ...)
GIS and 5G (high-speed mobile communication)
Everyone knows that the significance of 5G is not just the 5th generation mobile communication, but the fast. But the point is whether it is faster than 4g, no, it is that his speed reaches a certain threshold, a threshold with high bandwidth and low latency. Faster does not necessarily make sense, the significance lies in this threshold. The basis for the realization of the Internet of Things lies in this threshold, but is it just the Internet of Things? In the process of conversion from 2g to 3g, one cannot imagine. Speed (low latency) is not only speed, but high bandwidth is not just a large amount of data streams. Changes in the carrier will inevitably lead to changes in the form of content delivered. As a metaphor, as a carrier of information flow, every time the communication speed reaches a meaningful threshold is like people's transportation from walking to horse riding to cars, ships and planes, it seems that only the speed of transportation has become faster, But in fact, both people's activity space and production activities have been greatly affected, and people's way of thinking has also undergone a huge change. "Towing up 90,000 miles" has turned into a go-and-go trip. The era of "Family Books Reaching Ten Thousand Gold" is unimaginable. Of course, this example is not appropriate. Perhaps it corresponds to the revolution itself, and the content form and technology (such as short videos) of transportation and information correspond to the first product of the revolution. It seems that people's changed lifestyles are more appropriate.
There is so much nonsense, just to show that high-speed communication will inevitably have a huge impact on the form and technology of all information-related industries. The Internet of Things is just one of the things that can be clearly met (the second part will explain in detail), and truly revolutionary changes have occurred What should happen is that the carrier that carries the information flow has changed. There are two situations: one, this carrier may exist for a long time and be given new vitality; second, it may be a new innovation. Let ’s talk about the old form of the second spring, such as short video, after all, after the birth of the video, "short" video and long video have existed, but the reason why it is so popular now that it can be treated independently and differentiated, in the final analysis is intelligent mobile Products of equipment and high-speed wireless networks (if market demand and social attributes are not discussed), there are many, and so on, two-dimensional codes, deep learning, NFC, etc .; another is a new form of innovation, which has not been before or Yes, but it has very little influence and can hardly survive, but in the new environment, it grows like a hormone. In this case, the market demand is often a blowout growth, even far exceeding its growth rate, until the original technology There are growth dividends that squeeze out slowly, and market demand is calm and stable. These two types are not necessarily opposed, and are often integrated, such as DeppLearnig. And what does this have to do with GIS?
The point is whether GIS will have a new form of information bearing. This form can be innovative or old tree blooming. GIS, as an interdisciplinary subject, has always been something that others have done well. We can use it. So can we create or improve ourselves by combining the characteristics of high-speed communication? Of course, competing for who to do is not the point. I mainly want to show what I think should be a possible direction of combining 5G with GIS. When solving problems, when the traditional data form or transmission form is not satisfactory, I should ask myself, in the case of high-speed communication, can I change or optimize the space problem by changing the form of the information flow carrier What about the expression or explanation? I think there will definitely be, like 2d to 3d, 2.5d, not just the improvement of the algorithm, I think it is mainly the improvement of computing power and storage that provides the necessary conditions to give the researchers who seize the opportunity to follow the trend Study the possibility of high-dimensional algorithms.
So to sum up, I personally think that the impact of 5G on GIS is to ensure the information flow in the connected Internet, and more options for the form of information flow.
GIS and Internet of Things
The characteristics of the Internet of Things must be heard by everyone, and the most exciting thing is the connection. The connection of the Internet of Things is of course inseparable from 5G (high-speed communication), but I deliberately put the existing Internet connection on the top, and the Internet of Things that has not yet been widely implemented is placed below.
