Paper代写：Development of GIS－r51due

下面为大家整理一篇优秀的paper代写范文- Development of GIS，供大家参考学习，这篇论文讨论了GIS的发展。作为一门新兴的技术，GIS产业随着计算机技术、通信技术的发展而迅速发展。GPS可以实时的获取任意空间位置的地理坐标，并且定位精度也很高，还可以用来测速、导航等。GIS则利用这些数据及时的获取未知点的空间坐标或者对已知的空间坐标进行修改与更新，提高GIS的工作效率及精度。

As a new discipline in the 21st century, with the rapid development of computer, the application of GIS permeates every corner of people's life, improving people's quality of life, bringing convenience to people and making people's life indispensable to GIS. The development of GIS is undoubtedly everyone's focus. Of course, with the cloud computing, Internet + and some other technology put forward, we know that the geographic information industry will usher in its own peak. The article will discuss the future development trend of GIS from the aspects of data standardization, 3S integration, network GIS and mobile GIS.

As an emerging technology, the GIS industry in our country develops rapidly with the development of computer technology and communication technology. In recent twenty years of development, the GIS industry has enjoyed considerable technological level and industrial scale so far. Now GIS is applied and plays an important role in a large number of fields such as military field, traffic and environmental assessment, geographical planning, public facilities management, resource investigation, telecommunications, energy, electricity, etc. However, there is still a great development of GIS Space.

At present, most geographic information systems use different data formats and are developed based on independent, specific and closed platforms, and there is no data interaction between them. Therefore, there are great differences and differences in the organization of geographic data. In addition, many human activities have their own distributed features. Geographical information is distributed in nature. Data production departments in different regions and different industries correspond to specialized data servers. With the establishment and application of large-scale trans-regional GIS projects, especially the recent rise of "digital city" and "digital earth", it is imminent to solve the distribution and sharing of geographic operations.

Opened in 1996, the Geographical Information Union was established in the United States and proposed the Open Geospatial Interoperability Specification and proposed a software framework for distributed access to geographic data and geo-data processing capability. The software framework was proposed so that data Operation is possible. Major developers have interoperable through the use of public interface templates described by the specification, thus solving a series of problems caused by different data formats. Realize data standardization at the same time, promote the development of GIS.

GPS is a global positioning system and is a modern tool for realizing rapid and precise positioning of space entities. GIS is a geographic information system, which is an effective method for collecting, storing, processing, analyzing and displaying spatial information of spatial entities. He can quickly, all-round, real-time, large-scale access to spatial information images, the effective combination of these three known as 3S integration. Geographic Information System (GIS) has good ability to process and analyze spatial data. However, the source of spatial data is very limited, which restricts its development. Remote sensing is an effective means and method of obtaining spatial data. Their research objects are all spatial entities, but remote sensing mainly focuses on the collection and classification of spatial information. GIS focuses on the storage, management and analysis of spatial data. In this way, the advantages of both are used to combine the two organically. Using remote sensing can provide geographic information system with a large amount of effective and real-time spatial data, and modify the geographic information system data. Remote sensing processing can make use of GIS data to enhance the accuracy and accuracy of the results. Such remote sensing promotes the development of geographic information system, and geographic information system lays a solid foundation for the development of remote sensing.

Another important source of GIS data is GPS. GPS is the most mainstream contemporary positioning and navigation system, accounting for a large proportion of the global navigation industry. It and the combination of GIS there will be what kind of spark.

GPS real-time access to any spatial location of the geographical coordinates, and positioning accuracy is also high, but also can be used to speed, navigation and so on. GIS can use these data to obtain the space coordinates of unknown points in time or modify and update the known space coordinates to improve the work efficiency and accuracy of GIS. At the same time, GIS is a good and important tool for data processing, integration and application of space and space in GPS. The two are closely linked and open up a broader world in different applications in many fields.

With the rapid development of computer networks, people gradually get information from the traditional media such as television and paper newspapers to a more convenient and faster computer network. This combination of network and GIS has become a necessary trend. WEB-GIS is based on the Internet platform, client application software using network protocols, the use of geographic information systems on the Internet. WebGIS can be used to deal with a large number of special data types, especially the processing of vector data. It uses web browser as the application working platform, can operate vector data on the client side, Can realize the function, improve the running performance of the computer, and can call various types of data, graph, picture remotely through the network, these advantages have reduced the limitation of the traditional GIS greatly, expanded the application range of GIS, promoted the development of GIS space. VR-GIS is a combination of geographic information systems and virtual reality technology. Mainly in order to improve user experience, enhance the visual characteristics of GIS. Virtual reality technology is a kind of computer simulation system that can create and experience the virtual world. It uses a computer to generate a system simulation environment of interactive 3D dynamic scene and entity behavior based on multi-source information fusion, so that users can immerse themselves into the environment in. The essence of VR-GIS is actually a traditional "GIS", just integrating VR technology into GIS and using it as the main user interface and interaction method, but its essence has not changed. It still has all the functions of the traditional GIS system . A good VR-GIS software should be able to represent the data in a real and natural way. It has the advantages of three-dimensional database, allowing users to observe and interact in real time at any angle, so as to give the user a better operating experience and realize the combination of VR and GIS the real purpose.

The advent of big data set off a frenzy in this world, where the mobile terminal has accounted for a large proportion and can not be ignored. Therefore, the development of mobile GIS is the inevitable trend of development. With the advent of some map softwares, such as Baidu Maps and Gao De Maps, people are increasingly able to feel the changes that GIS has in people's lives and the convenience lifestyles they bring. People's lives can not be separated from GIS.

From the advent of GIS, it has only been a few decades ago that it has integrated into the world and changed people's way of life. As a newcomer to the information industry, it plays an important role in it and is growing at an unprecedented rate. I think we should learn the advantages of the current GIS, combined with contemporary emerging technologies to better promote the development of GIS. GIS has gone deep into all walks of life. With the development of GIS becoming better and better, it will play an increasingly important role in our life and at the same time we will rely more and more on it. But the world adds more uncertainty and possibilities because it is what contemporary society needs. In the new era of geographic information, we will face even more challenges. In the new era of geographic information, the world will become better.
