The power system is developing towards a high degree of informatization and automation, and the scale of the power grid is expanding. Therefore, it is necessary to manage huge power equipment and facilities data, user data, and planning data. To some extent, scientific decision-making depends on the amount of information held by decision makers. Power generation, substation, and transmission systems are complex systems that contain a large amount of information.

C ++ open source GIS middleware Class Library: Gdal (raster)/OGR (vector) provides various types of read/write support Geos (geometry engine open source) is a class library for space topology analysis based on C ++ and is released following the lgpl protocol. The geos Class Library provides a wide range of spatial topology operation functions to determine the relationships between geometric objects and form new geometric objects after spatial analysi

I. Preface As we all know, two-dimensionalGISWith the rapid development of computer software and hardware and relational databasesGISTechnologies have been improved. It has unparalleled advantages in analyzing geographical information. Some macro geographic information, one-dimensional geographic information, such as rivers and highways, and two-dimensional geographic information, such as vegetation, lakes, and population quantity, in terms of analyzing and processing the geographical informat

ArcGIS Server is the newest server end of ESRI, which can achieve two major functions: 1, the development of a powerful web GIS system; 2, the development of distributed GIS system; The ArcGIS server's kernel, like ArcGIS desktop and ArcGIS engine, is the Arcobjects library. The so-called web GIS, in fact, is simply to use web technology to encapsulate Arcobjects

The GIS student programming is inferior to the computer, does the mapping is inferior to the study surveying and mapping, does not have the geography to study the geography, I now began to learn the programming how to learn also to be unable to learn the computer how to do?This is a simple question, so if you go to bed now and catch them, you can go to sleep.1, the family asked you to learn what professional, not to mention geographic information syst

In recent years it and space technology development, cloud computing, big data, real-time information, LBS, unmanned aerial vehicles, tilt photography and other new technologies emerging, Internet infrastructure construction achievements, broadband become a national strategic public infrastructure.GIS (Geographic information System), as an important tool of spatial information analysis and processing, has undergone great changes in its application requirements.

I saw Linlin reprinted "chatting about GIS professional orientation and personal positioning problems" (http://www.cnblogs.com/gisattic/archive/2005/05/19/158872.html), there are some supplements and ideas. The GIS software industry is still one of the highlights of the software industry in China. In terms of market share and software quality, I personally think it is still said, but on the other hand, wi

The current application of 3D GIS is mainly limited to 3D visualization and realistic visual performance, and its important 3D analysis and 3D operation functions are also very limited. The construction of three-dimensional spatial databases is still a complex and expensive comprehensive project. The production efficiency, quality control, data security, and effective storage and management of large 3D GIS

Professional is a GIS, attention web2.0 is this half a month of things. It's hard to know what web2.0 is. Recently on the Internet often see this example, Google on a search, only gradually understand. In my understanding, web2.0 refers to a series of new technologies and applications that are now emerging. Blog,wiki,rss,kijiji and the like, XML-based applications form an example of web2.0 in reality. Of course, the most essential feature of web2.0 is

【Abstract]This article introduces the development and evolution of the World Wide Web Geographic Information System and component technology, and analyzes the necessity and feasibility of using the component technology to build a World Wide Web Geographic Information System, this paper mainly analyzes the operating mechanism of component models in the World Wide Web Geographic Information System.The computer hardware technology and software industry have developed at an unprecedented speed, with

"Network GIS is a GIS product and application form in a certain period of time in the GIS development process. It can also be collectively referred to under all GIS systems" [1]. According to this definition, we can summarize all Internet-based distributed spatial information management systems into the concept of netw
