Application of design patterns in GIS I. Overview of design patterns With the wide application of object-oriented technology, software reuse has been adopted in more and more development projects. In the process of studying software reuse, the concept of design pattern was proposed. The so-called design pattern is a summary of some experiences in Designing object-oriented software. Its appearance can be said to be an important milestone in the develop

Like many people, I also deployed my GIS Major. I searched the internet for what this major did before I got into school, and how I got employed. As a result, I have not completely done what HD GIS does, what it can do, and what it can do. It is not easy for me to enter a school, so I cherish it very much. I want to learn something and find a good job. So I found a senior in the freshman year and asked him

Write in frontRecently began to study open source GIS, the domestic open source GIS data is very few, but is based on. NET is few. So decided to summarize their research data, technology is to share, this series (the plan is to write a series, if I can stick to the words) part of their own summary, partly from the network excerpt.Technical SolutionsThe main demand is to use B/s architecture, the front-end d

0 reply content: first of all, thank you for your invitation. Let me talk about it: 1. A significant new feature of HTML5 is that the browser supports GPU acceleration. At this point, many GIS functions that cannot be solved under HTML4 but can only be implemented by C/S, for example, a very popular GIS 3D application can be used for some small and medium-sized scenarios. In addition, Canvas will accelerat

There are many map development companies in Shanghai. Generally, companies that require map applications will search for GIS development enterprises in beishangguang region on their websites. Some companies in the Central and Western Regions apply technologies such as map development in business activities. Looking for professionals to develop GIS map applications often costs a lot. In order to better imple

Some time ago, a 3D GIS project in the studio passed the acceptance test. The project owner was the southern county Meteorological Bureau. The studio only invested two people to perform rapid development on the koalagis platform, it took about two months to complete the system development of the entire project. Although some problems were encountered during the period, such as demand changes and platform performance bottlenecks, they were solved throu

1. Geographic Information System (GIS): a new discipline integrating computer science, informatics, geography, and other sciences, with the support of computer software and hardware, it uses the theory of system engineering and information science to scientifically manage and comprehensively analyze geographical data with spatial connotations, to provide spatial information systems for planning, management, decision-making, and research.

Last year, I made a solution, Supermap + sqlserver 2000, which was configured for several days, I also went to Supermap for two days of training, and the demo was still problematic. Later, I put this requirement into consideration. Remove it (you have to spend money to buy software, and there is also a development cost, the actual use is not big) Another similar solution was made two days ago. the guiding ideology of this time is to use open source as much as possible. InvestigatedTwo days ago,

Long ago, ESRI There is a product named "..." and "arcexplorer. This Explorer is not another explorer, and arcexplorer is not popular nowArcGIS Explorer. At that time, it seems that there was no such thing as ArcGIS, and some were ArcInfo, ArcView, Mo, the good old days.GIS , It will not be so depressing, so you can only blame yourself for not catching up with good time. Back to the beginning, arcexplorer is nothing more than an esri gis data.
