Some time ago, a 3D GIS project in the studio passed the acceptance test. The project owner was the southern county Meteorological Bureau. The studio only invested two people to perform rapid development on the koalagis platform, it took about two months to complete the system development of the entire project. Although some problems were encountered during the period, such as demand changes and platform performance bottlenecks, they were solved throu

1. Geographic Information System (GIS): a new discipline integrating computer science, informatics, geography, and other sciences, with the support of computer software and hardware, it uses the theory of system engineering and information science to scientifically manage and comprehensively analyze geographical data with spatial connotations, to provide spatial information systems for planning, management, decision-making, and research.

Last year, I made a solution, Supermap + sqlserver 2000, which was configured for several days, I also went to Supermap for two days of training, and the demo was still problematic. Later, I put this requirement into consideration. Remove it (you have to spend money to buy software, and there is also a development cost, the actual use is not big) Another similar solution was made two days ago. the guiding ideology of this time is to use open source as much as possible. InvestigatedTwo days ago,

In front of the "Baidu map, Echarts integration HT for Web network topology diagram application" We have introduced the Baidu map and the HT for Web integration, we are today to talk about the integration of Openlayers and HT for Web.The HT for Web, as the logical topology graphics component itself, does not have GIS capabilities, but can be fused with a variety of GIS engines, namely its client components,

In the early 21st century, that is, the life of our generation yesterday and today, along with the "Space Awakening", GIS is gradually known to people. Geographic information system based on geo-principles is called the third-generation geographical language in academia. This concept was first proposed by Mr. Peng, the father of China's GIS. This "Space Awakening", in today's view, is even more applied in t

I had nothing to worry about this afternoon. I accidentally reviewed the MySQL manual. I used to check the content of the manual very well, the focus is on some basic details of SQL statements, MySQL performance parameters, and storage control management. However, today I accidentally discovered an important feature of MySQL, that is, MySQL also has the storage function for spatial data related to GIS, which suddenly aroused my interest, so I also foc

Since the beginning of the last century , electronic map application has received people's attention, but due to the limitations of the Times and the development of market economy is immature. the application of GIS system has not been used very well. Only a handful of state institutions and military systems can use these applications. With the development of technology and the demand of market economy development, especially the birth of standardize

I am a newly graduated GIS undergraduate graduate, currently engaged in GIS software application development in Hangzhou. In the project development always feel that their programming level is not enough, so I want to find some open source GIS small projects to research, so as to improve their programming ability and project development ability.

Semantic (semantic) and Its Semantic Web First, let's talk about semantics. For personal understanding, semantics is meaningful information. For example, if we say "B-u-s" separately, it doesn't make any sense, but if we say "bus ", in English, it is a bus. In academic research, the semantics (semantic) was proposed as the "Semantic Web" (Berners-Lee, T ., hendler, J ., lassila, O ., 2001. the Semantic Web. scientific American, 28-37 .), maybe earlier. What is Semantic Web? The so-called Sema

Google Map incorporated the street view model into the public application, and suddenly found that the original WebGIS still works like this. This is a surprise for the innovative company. In the GIS industry, it is a very basic function to display the query element information through map query. For example, click the international trade tower on the map to display some related properties of the Overseas Trade Building, including the specific address
