of data sources, such as POSTGIS,GML,SHAPEFILE,WFS, and standardizing the data. The feature interface is defined in Geotools, and data from different data sources is read out and unified into the implementation of the feature interface that contains a geometry member (defined in JTS). In this way, the further operation can only be oriented to feature,Eliminates the high-level software to the different data source interpretation process. In addition,

The previous article has already talked about the drawing function of the elements, since the elements are drawn out, the painting should be saved up, then how to save it. This one is to explain how to save the elements of a good drawing. Individuals have used two methods of saving elements, one is through the WFS directly save the elements of the storage, the other is through the Ajax method of the Project Server-side to save to the database.First

using them as a side-by-side concept is clearly misguided from the start-and it is this misleading that makes most people focus too much on the tactical aspect of polymorphism, even to the point of almost malicious exploitation, while ignoring the strategic aspects of the problem, This makes it easy for the software to be designed as a thin piece of excrement (which will be discussed in detail later).In practice, the first meaning of inheritance (rea

Keywords: Open Source WebGIS platform This site introduces you to the International Open-source WebGIS project, which has common features: free use and open source code (for specific usage rules, see the lisense files on each platform ), we hope to bring you into the broad open source GIS world.

been stuck inAjaxThe door is out. Its HTML viewer mode can transmit ArcXML data and images, and use JavaScript scripts to control operations while using DHTML technology to display maps. This is only a key part of asynchronous transmission. So,AjaxIt can fully undertake the implementation of the WebGIS client and improve user experience.In WebGIS that complies with OGC specificationsAjaxIt is extremely appropriate to implement the client. The obvious advantage is that it achieves the common cli

Openlayers is a javascript package developed by metacarta for the WebGIS client. The current maximum version is 2.5 V and is released through BSD license. The methods used to access geospatial data comply with industry standards, such as the WMS and WFS specifications of OpenGIS. openlayers adopts the object-oriented JavaScript method for development, at the same time, I borrowed some components from the prototype framework and the RICO library.

[Post] tips for the Mongolian army to conquer EuropeIn fact, the cavalry of the Mongolian army cannot defeat heavy armored cavalry in Europe one by one at all times, the spears and swords of heavy armored cavalry in Europe are much more lethal than the knives, spears, or langes of the Mongolian cavalry. The horses of European cavalry are far more advanced than those of Mongolian horses. However, the strategy and tactics of the Mongolian cavalry are far from those of the European cavalry. The bat

Development Method of an organization, and the business value is reflected in it. For a long time, our programmers have been good technical thinkers. We are always good at solving project problems from a technical perspective. However, whether a software system is truly available is reflected by the business value it provides. Therefore, instead of sticking to technologies that are never enough to learn every day, why not think about our focus in the direction of business value provided by soft

developing complex models, but they require direct access to the information stored in the Data warehouse relational structure. In the face of such applications, you must consider the capabilities of the Data warehouse. A few users can easily consume 50% or more of their resources on the Data Warehouse platform at peak times. Resource consumption is so huge because of the complexity of the data access process and the large amount of data processing.4th stage: Operational orientationThe 4th phas

following things:(1) The database view can be published in GeoServer as a table, while GeoServer's sqlviews can not only implement simple query publication, but also input parameters as the condition of query view.(2) Sqlviews can publish stored procedures or function of the database to perform more complex logical operations and queries.(3) SQL views query can be parameterized by string substitution, parameter values can always be used in WMS and WFS
