gis for beginners

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

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 has the storage function for spatial data related to GIS, which suddenly aroused my interest, so I also foc

well as remote sensing image stretching parallel computing described in the Application of Distributed Parallel Computing Technology in remote sensing data processing. The common feature of the above articles is to transform the algorithms of different branches in traditional remote sensing image processing in parallel so that massive data can be processed quickly and in real time on the cluster. Data Division in Distributed Parallel remote sensing image processing discusses how to reasonably

Collect and organize open source GIS Projects Based on. NET NASA World Wind NASA World Wind is a Windows form system developed using. net. It provides a global positioning function from the perspective of the earth, similar to Google Earth. It combines images taken from satellites by the National Aeronautics and Space Administration (NASA) that are applied to blue marble, Landsat 7, SRTM, modem5, and more.Link:Http://www.worldwindcentral.com/w

The following are some open-source GIS projects that I have analyzed or used on the. NET platform. First, we would like to invite you to make a positive response. I will update it in time to ensure that all the items listed here are up-to-date, most valuable, and have not died yet...

Today, I heard a friend talk about the definition of the underlying GIS development in the group. I thought it was quite fun and I turned around. 1. Combined with the second-and third-dimensional Secondary Development of specific industries, based on the mainstream GIS platform (secondary development, not the underlying development)2. rendering 3D images of specific industry models on the extension interfa

Today, the source code is pasted on. Please give me more criticism. I hope you can point out some mistakes. Thank you. In the future, I will take the time to learn how to deal with special cases and add them. I hope you will have more support. Source code structure: Source code is attached respectively: 1.

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

nearby houses, you can also use your own conditions to selectively display the houses that meet your needs, which makes it easier for you to choose, and increases the user experience in disguise, so as to increase sales. How can we develop such an important feature? The implementation of this function is inseparable from GIS map development. For an integrator or software development owner who does not understand
