There are many map development companies in Shanghai. Generally, companies that require map applications will search for GIS development enterprises in beishangguang region on their websites. Some companies in the Central and Western Regions apply technologies such as map development in business activities. Looking for professionals to develop GIS map applications often costs a lot. In order to better imple

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,

Long ago, ESRI There is a product named "..." and "arcexplorer. This Explorer is not another explorer, and arcexplorer is not popular nowArcGIS Explorer. At that time, it seems that there was no such thing as ArcGIS, and some were ArcInfo, ArcView, Mo, the good old days.GIS , It will not be so depressing, so you can only blame yourself for not catching up with good time. Back to the beginning, arcexplorer is nothing more than an esri gis data.

A simple database access layer based on EntityFramework Core, applicable to lightweight database services and lightweight Databases The code of this access layer is actually from a senior in the garden. I just thought it was good and recorded it. The access layer needs to install EntityFramework Core through Nuget, but I personally think EF 6 can also be used. It is best to match databases with SQL Server (

string by "/" and into the array $getparam. The reason behind the for loop is starting from 2 is because $getparam[0] represents the controller, $GETParam [1] represents the method. These are not parameters, they are all in the $_get, and they are some parameter information. The following controller name and method name is the first detection of the existence of $getparam, if it exists in the $getparam, if it does not exist then the detection according to the controller nam

In the early 21st century, that is, the life of our generation yesterday and today, along with the "Space Awakening", GIS is gradually known to people. Geographic information system based on geo-principles is called the third-generation geographical language in academia. This concept was first proposed by Mr. Peng, the father of China's GIS. This "Space Awakening", in today's view, is even more applied in t
