"VC + + General GIS function Development solution" Source code is based on vc++6.0 MFC class Library, developed on the Win2000 platform. The interface section uses a lower version of the Cj60lib Open Source Library, where the user can replace the high version or other interface library, which is not a commercial part of the program.

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 stores spatial data related to gis.
I had nothing to worry about this afternoon. I accidentally reviewed th
2.5 Comparison of vector and raster data structuresEarly in the development of computer-aided cartography and GIS, vector processing technology was originally quoted, and raster data processing began in the middle of the 70 's. A few years ago, these two data structures were hard to be compatible, so they caused a lot of inconvenience to the use of data. In recent years, it has become more and more clear that the differences between grid and vector da
This is an experiment that I did when I first came into contact with the Google map API last year. I didn't do any further work in the future, but I wrote a draft and kept it in my blog post. Although some ideas are naive, there are even some errors. Today it seems that there are still some reference values, so I will release the draft for you to have a look. The original text is as follows:

Introduction
GIS (Geographic Information System), GPS (global positioning system), RS (Satellite Remote Sensing Technology) three large space science technology, known as "3 S" technology, it is regarded as an important cutting-edge technology for the development of information science and technology in the 21st century. Particularly in th

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
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
Sramana Mitra pointed out in the article that web3.0 is defined as Web 3.0 = 4c + P + vs (4C: content, commerce, community and scenario; P: Personalization; vs: vertical search ). As a result, Will personalization become a new breakthrough in the development of geographic information? I think so. Goodchild also raised the concept that everyone is a sensor. The intention should be similar. Various spatial analysis algorithms have been well developed for the development of
I-gis Geoscene3d v10.0.11.495 Three-dimensional geological modeling softwareGeoscene3d enables the visualization of large amounts of earth science data. such as deep wells, geophysical data, soil and water chemistry, topography surfaces and geological layers. In addition, you can use software to build geological models in a well-defined modeling process. From a manual or semi-automatic generation layer interpretation point, the layer surface is genera
In the past two years, we have seen the saying that GIS is integrated into the it mainstream from time to time. At least one piece of information can be reflected, and the GIS industry is out of touch with the IT mainstream. One link to this gap is the architecture of the software or system. The system here refers to the so-called "enterprise software" applied to a department or industry, or the management
Any theme in the material world is firmly branded with time and space. More than 80% of people's production and life information is related to geographical location. Geographic Information System (GIS), as an important tool, technology and discipline for obtaining, processing, managing, and analyzing geospatial data, has received wide attention and rapid development in recent years.
From the perspective of technology and application,
Today, I took a look at the technical support post written examination questions of digital in Wuhan. One of the questions (attributes of GIS data include ___ ____) is my professional knowledge, but I cannot say it myself, the information is summarized as follows.
GIS data includes spatial data and attribute data.
Spatial data mainly describes the location information of spatial objects. Generally, the co
The most important thing for ESRI in was the launch of ArcGIS engine9.2. I only read the desktop and engine sections of this version, which is really amazing, especially ArcGIS Engine, A large number of new elements, components, and technologies have been added to reduce the development process and difficulty. The launch of this version makes the Basic Books on ArcGIS on the market outdated and need to be updated.
In, I personally used ArcGIS Engine to make a fewProgramMy personal satisfaction

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
