" we The solutions provided do not imply that the e-form++ Visual Graphics component library can only develop these aspects of the application, in fact e-form++, like any other third-party C + + component library, contains hundreds of features that can be used separately. As with Qt, MFC, and so on, you can independently decide if you need a feature in e-form++, generally speaking, as long as you need graphics display, need flowchart, control chart, printing function, typesetting function, simul

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

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

Those who are interested in WebGIS and open-source GIS software have translated the book "GIS for Web Developer" (Scott Davis, progmatic Press) introduced by the Electronic Industry Press's liberal arts viewpoint, this is a book on open source software of WebGIS. It introduces some basic concepts of GIS, open source tools of
