I saw an article on 3snews about 3D GIS, which is well written and reproduced here. How far is GIS from two-dimensional to three-dimensional technology breakthrough? Http://www.3snews.net/html/06/n-21706.htmlSummary 　　Geographic InformationSystem (GISOriginated from North America, modern geography andSpatial InformationThe combination of science. After decades of development,

This is a summary of my graduation thesis. GIS application in Urban Planning 1) role of GIS in Urban Planning (1) GIS provides intuitive and rational planning tools Commonly used CAD software, such as AutoCAD, usually has strong graphic ability and weak management ability relative to attribute data. Therefore, CAD can only be used as drawing software [30]. Howeve

**GIS电子地图定制开发技术**The definition of "geographic Information System" is made up of two parts. On the one hand, geographic information system (GIS) is a new interdisciplinary subject, which is the theory and method of describing, storing, analyzing and outputting spatial information. On the other hand, geographic information system (GIS) is a technical system, which

According to the actual work needs, the author uses SVG and related technology in Web browser to realize the Web GIS Management System (hereinafter referred to as Webgis), and obtains the very good result. This system includes the design of the server and the client, which is to handle the data storage and the dynamic loading of the data, th

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 http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a problem, and the latter provides the object of solving the problem.The term "algorithm" d

To process a large amount of GIS data and its format, programmers have created several open-source libraries and GIS suites. This article briefly introduces the range and depth of

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

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
