relatively simple system, just iffy a little bit of meaning, and even a little learning or innovation meaning.Plus the last published part of the paper, so the whole system is a complete complement.

I am a newly graduated GIS undergraduate graduate, currently engaged in GIS software application development in Hangzhou. In the project development always feel that their programming level is not enough, so I want to find some open source GIS small projects to research, so as to improve their programming ability and project development ability. Search on the Int

Semantic (semantic) and Its Semantic Web First, let's talk about semantics. For personal understanding, semantics is meaningful information. For example, if we say "B-u-s" separately, it doesn't make any sense, but if we say "bus ", in English, it is a bus. In academic research, the semantics (semantic) was proposed as the "Semantic Web" (Berners-Lee, T ., hendler, J ., lassila, O ., 2001. the Semantic Web. scientific American, 28-37 .), maybe earlier. What is Semantic Web? The so-called Sema

Google Map incorporated the street view model into the public application, and suddenly found that the original WebGIS still works like this. This is a surprise for the innovative company. In the GIS industry, it is a very basic function to display the query element information through map query. For example, click the international trade tower on the map to display some related properties of the Overseas Trade Building, including the specific address

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

To be honest, since I posted this algorithm, I have never followed this article any more. So many of my friends did not see the message and replied in a timely manner. Here I say "sorry ". This buffer algorithm is an algorithm used in our project. It is all written by myself based on my own paper. It is not well handled in many places, but it is basically common to deal with it, the buffer accuracy rate is still between 60%-80%. Because I have been busy working on projects, this algorithm has
