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

Its communication protocol is hyper text transfer protocol ).Texts on the World Wide Web have special requirements:

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

increase maintenance and troubleshooting costs When a component needs to call multiple services, different services may initialize their instances in different ways. Developers have to understand the APIS initialized by all services so that they can be correctly used in programs. The initialization process of some services consumes a lot of resources. Therefore, repeated service initialization will greatly increase the resource usage and performance consumption of the system. The program requ

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.

In the previous section, we made a simple container to basically implement registration and query of types/objects.CodeCurrently it is relatively stable, and there is no need to deal with various factory instances or understand the ing between interfaces and factories. However, the containers we implement have some problems: 1) Each interface type can only register one corresponding component instance (the interface type is the key in the dictionary, and the key cannot be repeated. The

There is a boom in the Java community that uses lightweight containers to help assemble components from different projects and integrate into a cohesive application. These underlying containers have a common pattern of demonstrating how they assemble components, and they propose a concept called "control reversal" (Inversion of controls). Next we delve into how the pattern works in "Dependency Injection" (Dependency injection) and compares it to the service

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
