The HT for Web, as the logical topology graphics component itself, does not have GIS capabilities, but can be fused with a variety of GIS engines, namely its client components, to achieve seamless integration of logical and physical topologies, and this chapter will specifically describe the HT for Web and development free Openlayers map combined with the application of key technology points, the introducti

SharpmapSharpmap is a map rendering class library based on. NET 2.0 that uses C # to render GIS data in the form of Esri Shape, PostGIS, MS SQL, and other formats by extending the map data provider, such as those developed by other authors Oracle Spatial Provider. Sharpmap can be applied to desktop and web programs.Links: Http://www.codeplex.com/SharpMapNettopologysuiteNettopologysuite is the c#/.net version of the famous JTS topology suite, referred

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

1. Geographic Information System (GIS): a new discipline integrating computer science, informatics, geography, and other sciences, with the support of computer software and hardware, it uses the theory of system engineering and information science to scientifically manage and comprehensively analyze geographical data with spatial connotations, to provide spatial information systems for planning, management, decision-making, and research.

Last year, I made a solution, Supermap + sqlserver 2000, which was configured for several days, I also went to Supermap for two days of training, and the demo was still problematic. Later, I put this requirement into consideration. Remove it (you have to spend money to buy software, and there is also a development cost, the actual use is not big) Another similar solution was made two days ago. the guiding ideology of this time is to use open source as much as possible. InvestigatedTwo days ago,

In front of the "Baidu map, Echarts integration HT for Web network topology diagram application" We have introduced the Baidu map and the HT for Web integration, we are today to talk about the integration of Openlayers and HT for Web.The HT for Web, as the logical topology graphics component itself, does not have GIS capabilities, but can be fused with a variety of GIS engines, namely its client components,

Building information Modelling what is BIM? There are divergent opinions, the joy of pulling. The definition is a very difficult thing, the most error-prone answer is: through three-dimensional design + modeling + effects + virtual reality + Collaborative Design + system development, the impact of the project's entire life cycle, making ... Thus... At last...However, chatty's answer can only be to avoid making mistakes, and not to reflect the true interpretation of their meanings. Relative defin

Spatial Query and analysis are at the core of GIS, and most of the daily tasks of GIS engineering projects are related to query. GIS Query types can be divided into three types: simple attribute query, spatial location-related query, and joint query related to spatial location and attribute. In this topic, we will detail how to perform these three queries in Supe

Published in 3snews News Weekly 22nd "3D GIS" has become a hot term today. At a relatively large scale of GIS conferences and exhibitions, we can see all kinds of 3D GIS products, domestic, foreign, stand-alone, online, browsed, and analyzed, a thriving and lively scene, quite a 2dgis outdated, the feeling that the 3dgis era has come. In the past one or two yea

I had nothing to worry about this afternoon. I accidentally reviewed the MySQL manual. I used to check the content of the manual very well, the focus is on some basic details of SQL statements, MySQL performance parameters, and storage control management. However, today I accidentally discovered an important feature of MySQL, that is, MySQL also has the storage function for spatial data related to GIS, which suddenly aroused my interest, so I also foc

. Net-based Open Source GIS project Original post address: Http://www.cnblogs.com/reonlyrun/archive/2007/02/06/642008.html The following are some open-source GIS projects that I have analyzed or used on the. NET platform. First, we would like to invite you to make a positive response. I will update it in time to ensure that all the items listed here are up-to-date, most valuable, and have not died y

Since the beginning of the last century , electronic map application has received people's attention, but due to the limitations of the Times and the development of market economy is immature. the application of GIS system has not been used very well. Only a handful of state institutions and military systems can use these applications. With the development of technology and the demand of market economy development, especially the birth of standardize

When it comes to map making, many people will hook up with cartography the first time. Yes, many theories and ideas about cartography are well suited for GIS-based mapping. It can be said that the use of GIS for electronic map production, in fact, is also a small part of cartography.Cartography is a subject that studies the theory of map, the technique and application of map compiling. This science can be s

Currently, most of the GIS applications in China are under secondary development. Because for applications, the advantages of secondary development are obvious.1. ConvenienceSecondary Development has a low technical level. What we need to achieve is not the GIS technology, but the specific application of all implementations.Service. On the basis of understanding the business, it is convenient to use the

TrigonometryAnd spherical trigonometry. Let me surprise you: this stuff is overused. In your cases trigCan be avoided altogether by using simpler, but slightly more advanced, techniques, especially basic vector arithmetic. ElementaryDifferential geometry. This is the investigation of smooth curves and surfaces. It was specified ted by C.F. gauss in the early 1800's specifically to support wide-area land surveys, so its applicability to GIS is obvious

The following geographical information system application fields have answered these questions in their respective fields. Resource management) It is mainly used in the field of agriculture and forestry to solve the distribution, grading, statistics, and plotting of various resources (such as land, forest, and grassland) in the field of agriculture and forestry. The primary answer is "positioning" and "mode. Resource Configuration) All kinds of public facilities in the city, distributi

well as remote sensing image stretching parallel computing described in the Application of Distributed Parallel Computing Technology in remote sensing data processing. The common feature of the above articles is to transform the algorithms of different branches in traditional remote sensing image processing in parallel so that massive data can be processed quickly and in real time on the cluster. Data Division in Distributed Parallel remote sensing image processing discusses how to reasonably
