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,

[2] I am currently able to find only teaching books of a certain age, such as Python geo-spatial devlopment[1], and scattered technical articles. But the specific how to learn the application completely without direction, ask for advice. For example Mapfish[3], look at the introduction and feel very good, but will not use ...

Where is GIS?-- Discussion on ArcGIS (this article only discusses the future development trend of GIS software. It is purely self-entertainment. Incorrect opinion. Comments are welcome !) GIS is the abbreviation of geographic information system. As an industry, GIS should have the property of software engineering, but

???? Using GIS technology for cartographic mapping, the ultimate goal is to return to the cartography. The following are some of the classic requirements for map making in cartography:Maps must conform to reality, to human perception.???? This is the most basic of the map, each element of the map is shown with the actual entity corresponding, although sometimes in order to highlight the characteristics of the geographical features and moderate exagger

Self-accomplishment of GIS mapping staff (2)--Cartographic consciousness by Li Yuanxiang The last mention of some cartographic errors of GIS mapping personnel, mainly for the GIS cartographic staff to analyze some of the problems in the cartographic work. But how to improve the self-cultivation of cartography, but it is a very long process, this chapter mainly fo

Published in 3snews News Weekly 22nd "3D GIS" has become a hot term today. At a relatively large scale of GIS conferences and exhibitions, we can see all kinds of 3D GIS products, domestic, foreign, stand-alone, online, browsed, and analyzed, a thriving and lively scene, quite a 2dgis outdated, the feeling that the 3dgis era has come. In the past one or two yea

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

Application of design patterns in GIS I. Overview of design patterns With the wide application of object-oriented technology, software reuse has been adopted in more and more development projects. In the process of studying software reuse, the concept of design pattern was proposed. The so-called design pattern is a summary of some experiences in Designing object-oriented software. Its appearance can be said to be an important milestone in the develop

well as remote sensing image stretching parallel computing described in the Application of Distributed Parallel Computing Technology in remote sensing data processing. The common feature of the above articles is to transform the algorithms of different branches in traditional remote sensing image processing in parallel so that massive data can be processed quickly and in real time on the cluster. Data Division in Distributed Parallel remote sensing image processing discusses how to reasonably
