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

The MapGuide GIS system asked for help. An error was reported when connecting the SDF file with FDO. The solution was not found in a few days. mapguidesdf Currently, there is very little information about the GIS system on the Internet. However, most people use WebGIS. Here, MapGuide is used for GIS presentation and MapWindow is used for layers in the background,

GIS (4) -- add borders + the final simplified version of Marker and Brand for the js sogou map, gismarker In GIS (III)-brand logo style for optimizing sogou map of js edition, I shared my changes to Brand style. Now, let's unify the changes made to the Marker and Brand, and then make them a final optimized version. The main content of this optimization is: 1. Create a boundary first. Adding a boundary to a

I had nothing to worry about this afternoon. I accidentally reviewed the mysql manual. I used to check the content of the manual very well, the focus is on some basic details of SQL statements, mysql performance parameters, and storage control management. However, today I accidentally discovered an important feature of mysql, that is, mysql also stores spatial data related to gis. I had nothing to worry about this afternoon. I accidentally reviewed th

2.5 Comparison of vector and raster data structuresEarly in the development of computer-aided cartography and GIS, vector processing technology was originally quoted, and raster data processing began in the middle of the 70 's. A few years ago, these two data structures were hard to be compatible, so they caused a lot of inconvenience to the use of data. In recent years, it has become more and more clear that the differences between grid and vector da

This is an experiment that I did when I first came into contact with the Google map API last year. I didn't do any further work in the future, but I wrote a draft and kept it in my blog post. Although some ideas are naive, there are even some errors. Today it seems that there are still some reference values, so I will release the draft for you to have a look. The original text is as follows: 0. Description After some time of thinking, I recently tried a "Google map online vector Interoperabi

Through the Shaoxing county Pipeline Data Survey, 17 types of pipeline data have been fully established, and basic terrain data has also been established. These basic data reserves provide a powerful data basis for the establishment of the Shaoxing underground pipeline information system. Our company cooperates with Beijing Supermap software Co., Ltd. to develop and implement the geographic
