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.

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

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
