I saw Linlin reprinted "chatting about GIS professional orientation and personal positioning problems" (http://www.cnblogs.com/gisattic/archive/2005/05/19/158872.html), there are some supplements and ideas. The GIS software industry is still one of the highlights of the software industry in China. In terms of market share and software quality, I personally think it is still said, but on the other hand, wi

The current application of 3D GIS is mainly limited to 3D visualization and realistic visual performance, and its important 3D analysis and 3D operation functions are also very limited. The construction of three-dimensional spatial databases is still a complex and expensive comprehensive project. The production efficiency, quality control, data security, and effective storage and management of large 3D GIS

1. Accuracy of spatial databases Methods and Techniques for error handling and uncertainty error handling in geographic information data, including: Uncertainty error model; Error Tracking and coding; Calculation and Expression of errors in GIS applications; Data Accuracy Evaluation; Research on data quality, metadata, and data standards. 2. Study on Spatial Relational Language Based on the standardized form of geospatial concepts, using natural lang

In recent years it and space technology development, cloud computing, big data, real-time information, LBS, unmanned aerial vehicles, tilt photography and other new technologies emerging, Internet infrastructure construction achievements, broadband become a national strategic public infrastructure.GIS (Geographic information System) as an important tool for spatial information analysis and processing. Its application needs are also changing dramatically.Online content, convenient collaboration,

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

Use open-source projects to build a GIS Application System This article describes how to use an open-source international project to build a complete GIS (Geographic Information) application system.

Where is GIS?-- Discussion on ArcGIS (this article only discusses the future development trend of GIS software. It is purely self-entertainment. Incorrect opinion. Comments are welcome !) GIS is the abbreviation of geographic information system. As an industry, GIS should have the property of software engineering, but

???? 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

But how to improve the self-cultivation of cartography, but it is a very long process, this chapter mainly fo

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

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
