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

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

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

. Objects exist in the form of XML tags in SVG files, and object attributes are accessed by tag attributes. You can easily access these objects and attributes by accessing the DOM objects of SVG. Meanwhile, SVG also provides functions such as group management ( Introduction to SVG events SVG provides rich message triggering and Event Response functions to obtain user messages. For example, moving a map or clicking a mouse. Events can be defined in the

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,

Since the beginning of the 90 's [url=http://www.forbst.com] electronic map application [/url] 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

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

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

How to use the VBS to simulate the left mouse button click, left-click, right click? ...... The answer that is commonly found on the Internet is that VBS cannot be implemented, or is it to use a third party COM (ActiveX?) Component I'm disgusted with third-party components, and there's no portability to using third-party components, because this component is not necessarily registered in someone else's system. My advice is to try not to call a Third-

From: Open Source ChinaCommunityForumGeographic Information SystemGeographic Information Systems (GIS) software relies on datasets covering the whole earth. 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

Spatial Query and analysis are at the core of GIS, and most of the daily tasks of GIS engineering projects are related to query. GIS Query types can be divided into three types: simple attribute query, spatial location-related query, and joint query related to spatial location and attribute. In this topic, we will detail how to perform these three queries in Supe

" we The solutions provided do not imply that the e-form++ Visual Graphics component library can only develop these aspects of the application, in fact e-form++, like any other third-party C + + component library, contains hundreds of features that can be used separately. As with Qt, MFC, and so on, you can independently decide if you need a feature in e-form++, generally speaking, as long as you need graphics display, need flowchart, control chart, printing function, typesetting function, simul

How to Use VBS to simulate left-click, double-click, and right-click ?...... The answer found on the internet is generally that VBS cannot be implemented, or a third-party COM (ActiveX?) is used ?) Component. I am very disgusted with third-party components. using third-party components has no portability, because others do not necessarily register this component in their systems. I suggest that you do not call third-party components in VBS code unless your program is only written and used by yo

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

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.
