The link between Java and GISGeographic Information System (GIS) is a new frontier subject developed in the early 70. because GIS has powerful and unique functions in data acquisition and input, spatial data management, map extraction, automatic mapping, digital terrain analysis, data output and so on, it is in resource inventory and management, regional town planning, disaster prevention and monitoring, en

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

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

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,

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

Some time ago, a 3D GIS project in the studio passed the acceptance test. The project owner was the southern county Meteorological Bureau. The studio only invested two people to perform rapid development on the koalagis platform, it took about two months to complete the system development of the entire project. Although some problems were encountered during the period, such as demand changes and platform performance bottlenecks, they were solved throu
