Frankly speaking, it is difficult enough to give the proper definition to this matter. Shortly speaking, the Geographic Information System (GIS) is an opportunity to look at the surrounding world differently. To talk you without generalizations and images, it is a modern computer technology for mapping and analyzing objects of the real world, as well as events occurring on our planet. However, could you, please, answer the question “When is National GIS Day in 2021?”
Unfortunately, we are almost sure that the answer of the most part of the contemporary men and women will be negative. And that is the reason why we have made a decision to discover this matter in details.
Of course, it is impossible to explain, what day GIS Day in 2021 is, without taking into account the historical background of this event.
Unfortunately, we haven’t managed to find out any information about this special occasion establishers as well as about the fact why this holiday is celebrated just on November 18.
All in all the period from the early 1970s to the beginning of the 1980s is considered to be a period of state initiatives in the field of geoinformation systems. All over the world this project found massive state support, which stimulated the development of experimental work in the field of these systems based on the use of databases on street networks, navigation, urban waste and garbage collection systems, vehicle traffic management in emergency situations.
Since the first half of the 1980s, the period of commercial development of geoinformation systems began. A wide market for various software tools, the development of desktop geoinformation systems, the extension of their scope through integration with non-spatial databases, the emergence of network applications, the emergence of a significant number of non-professional users, systems that support individual datasets on individual computers opened the way for systems supporting corporate and distributed geodatabases. Since the late 1980s, geoinformation systems of the user level have appeared.
What does GIS Day mean? Frankly speaking, it is up to you to decide, whether this special occasion is important for you or you can forget about it completely.
We would like to mention that all in all, currently, GIS is a multi-million dollar industry that involves hundreds of thousands of people around the world.
GIS is actively studied in schools, colleges and universities. This technology is applied in almost all spheres of human activity, whether it is an analysis of such global problems as overpopulation, pollution of the territory, forest lands, natural disasters, and the solution of private tasks such as finding the best route between several points, selecting the optimal location of a new office, searching definite houses at its address, laying of the pipeline on the ground, various other municipal tasks.
The contemporary GIS involve five main components: high-quality hardware, modern software, various data, executors and well-programmed methods.
In its turn hardware is represented by a strong computer running GIS. Up to the present moment GISs have already worked on different modifications of computer platforms. It correspondingly means that you can choose everything you like from popular centralized servers to individual or even, if you need, to networked desktop computers.
The software contains all tools necessary for storing, analyzing and, of course, visualizing geographic kind of information.
Trying to find out the answer to the question “When is International GIS Day 2021?” we can’t but mention the following pieces of information.
This contemporary technology combines traditional and well-known operations, performed with databases, the most typical of which are query and statistical analysis. The main benefits are represented by full-fledged visualization and geographic analysis, provided with the maps. These typical features vary GIS from the other existing information systems.
Unique opportunities of this application involve in a wide list of tasks related to the analysis and forecast of phenomena as well as the events of the surrounding world, with the understanding and allocation of the main factors and causes as well as their possible consequences, with the planning of strategic decisions and the current effects of the taken actions.
Creating maps and geographic analysis are not something completely new. However, GIS technology provides a new, more appropriate modern, rather effective, convenient and quick approach to problem analysis and the challenges, which people are facing to in general and in particular. It automates the analysis and forecasting process.
Before GIS introduction, only a few organizations had the art of generalization and full analysis of geographic information for the purpose of reasonable adoption of optimal solutions based on approaches and means.
When is GIS Day in 2021, calendar will surely remind you. It is not a problem. The only thing you should remember is when November 18 comes.
Unfortunately, there are no traditions for this day celebration. And all in all it seems rather difficult to invent something for yourself.
This day you can watch something interesting (films or documentaries) as to this matter or to read as much information as you are able to find.
You can also load some GIS programs to your mobile and try to find some objects around. From time to time contemporary people even organize a specialized competition. The winner will be a person, who will find the definite place first.
National GIS Day Facts
In attempts to get the wide answer to the question “What is the date of GIS Day?” we usually want to find out something new about this matter.
We would like to tell our readers that GIS stores a great amount of information about the real world. It is always done in the form of a set of thematic layers, which are combined on the basis of geographical location.
This simple but at the same very flexible approach has proved its worth in solving a real variety of real problems: to track the movement of vehicles and public transportation, to detail the actual situation and planned activities and to simulate global atmospheric circulation. As you can see, these tasks are really very important in the contemporary world for the modern society.
Any geographic information contains various data about the spatial situation, whether it is a geographic or other coordinate reference, or a link to an address, postal code, electoral district or census district, land or forest area identifier, road name, etc.
When a person is using such links, he/she is involved in a procedure called geocoding. It is used automatically in order to determine the location or various locations of an object (objects).
All in all with its help you can quickly identify where you are and look at the map where an object or phenomenon you are interested in is located, for example, the house in which your friend lives or the organization you need, where an earthquake or flood occurred, which route is easier and faster to reach the point you need or at home.
