Recently on the Internet often see this example, Google on a search, only gradually understand. In my understanding, web2.0 refers to a series of new technologies and applications that are now emerging. Blog,wiki,rss,kijiji and the like, XML-based applications form an example of web2.0 in reality. Of course, the most essential feature of web2.0 is

???? Using GIS technology for cartographic mapping, the ultimate goal is to return to the cartography. The following are some of the classic requirements for map making in cartography:Maps must conform to reality, to human perception.???? This is the most basic of the map, each element of the map is shown with the actual entity corresponding, although sometimes in order to highlight the characteristics of the geographical features and moderate exagger

Self-accomplishment of GIS mapping staff (2)--Cartographic consciousness by Li Yuanxiang The last mention of some cartographic errors of GIS mapping personnel, mainly for the GIS cartographic staff to analyze some of the problems in the cartographic work. But how to improve the self-cultivation of cartography, but it is a very long process, this chapter mainly fo

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

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

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

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

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.
