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

the article "Designing reusable large-granularity GIS components using Visual Basic's event mechanism. First, you need to define the required variables, objects, and events. You need to use withevents to define a MapX object to respond to its events, and then define a connect method to pass the object instance to this object, and perform necessary initialization. The Code is as follows: Private const m_rulertoolid = 104.Private withevents m_mapx a

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

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,

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

Professional is a GIS, attention web2.0 is this half a month of things. It's hard to know what web2.0 is. 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

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

[2] I am currently able to find only teaching books of a certain age, such as Python geo-spatial devlopment[1], and scattered technical articles.

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 !)

???? 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.

The answer commonly found on the web is that VBS cannot be implemented, or that a third-party COM (ActiveX? Components I am disgusted with third-party components, and using third-party components is not portable, because this component is not necessarily registered in someone else's system. My advice is to try not to call third-party components in the VBS code unless your program just writes for your own use. (By the way, also try not to use the SendKeys method, the reason does not explain)Okay,
