connotation of new generation Web GIS " Next-generation Web GIS " is a web-centric, new GIS application model presented by ESRI in the context of the new GIS technology and the era, in which the resources and functions are further integrated and the providers of GIS services

【Abstract]This article introduces the development and evolution of the World Wide Web Geographic Information System and component technology, and analyzes the necessity and feasibility of using the component technology to build a World Wide Web Geographic Information System, this paper mainly analyzes the operating mechanism of component models in the World Wide Web Geographic Information System.The computer hardware technology and software industry have developed at an unprecedented speed, with

"Network GIS is a GIS product and application form in a certain period of time in the GIS development process. It can also be collectively referred to under all GIS systems" [1]. According to this definition, we can summarize all Internet-based distributed spatial information management systems into the concept of netw

three major applications of GIS The first category is the government application, "e-government" is the current government to strengthen the information construction of the new direction, refers to the modern computer, network communications and other technology support, government agencies day-to-day office, information collection and release, public management and other affairs in the digital, networked environment under the State Administration fo

1. introduction The current application of geographic information systems requires the organic integration of GIS and other systems such as MIS and OA. Therefore, most GIS systems are developed with component GIS as the core for secondary development. Therefore, with the rapid development of computer and geographic information technology and the gradual maturity

1. Curiosity First, GIS professionals should be curious. This curiosity is not just about geospatial technology, but about the world around us. In our work, we must actively consider the spatial relationship of phenomena, ranging from local to global, covering population, land use, transportation models, regional natural disasters, biodiversity, and global climate change. The number of new multimedia, sensors, and mass data sources has increased s

LAdvanced and practical "Sg186" is a high-standard information project. The GIS platform must meet both the advanced and practical requirements. The GIS platform has been applied in the power industry. LSupport for standards and specifications Supports OpenGIS data model specifications; Supports the Geographic Information Service Specifications of OGC, such as WMS, WFS, and WCS, in this way, data is s

ArcGIS Server is the newest server end of ESRI, which can achieve two major functions: 1, the development of a powerful web GIS system; 2, the development of distributed GIS system; The ArcGIS server's kernel, like ArcGIS desktop and ArcGIS engine, is the Arcobjects library. The so-called web GIS, in fact, is simply to use web technology to encapsulate Arcobjects

Beijing has now merged Chongwen and Dongcheng into Dongcheng, and Xicheng and Xuanwu into Xicheng. How does GIS merge them? The procedure is as follows: To back up the operated graph, first open "arccatalog ";Figure 1. Open arccatalog Select a work area;Figure 2. Select a work area Select the layers to operate and copy them.Figure 3. file backup Paste and rename the fileFigure 4. file backup and renameIn this way, the file backup operation is com

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

GIS. Based on actual work requirements, the author uses SVG and related technologies in a web browser to implement a Web GIS Management System (WebGIS), which has achieved good results. This system includes the design of the server and client. The server stores and dynamically loads the data to be processed, and the client displays and interacts with SVG data. This article briefly introduces some basic kno

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
