Today we will discuss a few things that are not closely related. If some people have their own unique insights on these issues or already know the technology, so please put it forward in your comments for discussion. Let's discuss it here ......1. Over the past few days, I have been busy testing and modifying the GIS system. I have found some bugs and new requirements. This not only changes the style and layout of the interface, but also rarely change

GIS outsourcing of zhongke yanyuan --- transportation integrated Geographic Information Platform, yanyuan gisA gis portal that integrates maps, services, and transport. It is a GIS portal that integrates maps, services, and transport, without complex settings and deployment, you can quickly create interactive maps and applications and share them with other people

Recently, I have tried to apply open-source GIS to commercial platforms. I have tried to use the structure of geoserver + postgis + OpenStreetMap. The main difficulties are data import and boundary issues, vector style sheets, etc. There are many import methods. You can refer to the Wiki of OpenStreetMap. The corresponding shapefile is used for the boundary. The source is also the content of OpenStreetMap. It is difficult to directly use S

Mobile GIS coincides with the timeThanks to the popularization of mobile intelligent terminal and the development of mobile Internet, with the development and application of GIS technology, more and more enterprises and ordinary consumers begin to realize the great potential and value of mobile GIS.Mobile GIS lightweight and flexible, wide audience, anytime and a

I have always wanted to write this thing, although a flexview or other development of GIS framework is simple, but the business system more when you are not the framework, the requirements are not the same, the layer is not the same you do not change, more to a certain extent to maintain the trouble, Deploying so many projects and other business developers (who don't understand GIS) will have to interact wi

standardized management of geological data, and the lack of corresponding security measures. The powerful data management function of GIS not only provides analysis and decision support for accident prevention and response, but also saves resources and avoids repeated investment in geological surveys.1. Drilling Data Management: the city's unified geological drilling database is established for overall planning. The quick batch import function can be

Discuss the design of plug-in GIS framework and plug-in gis framework Three years ago, I bought a GIS plug-in framework book from Jiang potao, as recommended by my senior brother. At that time, while reading a book, I made a complete implementation of the examples, which benefited a lot. Later, a plug-in C/S system was developed for the project, using the MEF fra

Project experience: the establishment of the GIS preliminary work form and the construction of the project gis form Not much. The preliminary work is just done. The GIS platform system can coordinate and unify the whole water supply system. Based on the pipe network, the system establishes functions such as water supply network planning and design, configurat

Today we're going to talk about a couple of things that don't have much to do with, and if someone has a unique perspective on these issues, or if they already know about the technology, then please put it in the comments for your discussion, so let's explore it. One, these days busy testing and modifying the GIS system, found a number of bugs at the same time also has a new demand, not only changed the interface style and layout and the code also has

1,GISService Area Analysis Location factors are a crucial factor in business analysis. Therefore, routine service area analysis is very important for store site selection. The service area refers to the main area of customer distribution. The sales volume or service turnover of the store exceeds that of its competitors. For existing stores, the service area analysis can be used to evaluate the market potential and business performance. For new stores, the service area can be used to discover Bus

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

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?

tags. This provides a possibility for the implementation of GIS. 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.

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
