return the geographical information data in the GML format. GML is an XML-based data format. It can completely reproduce data and is also an important form of OpenGIS data source. That is to say, the GML returned by WFS can continue to serve as the data source. In WFS requests, OpenGIS defines a filter standard to filter data and make WFS more flexible. On the o

specific implementations. Elements of the same geometric type and attribute type can be stored in a data source. A data source can have only one element type. Therefore, element types can be used to describe elements with similar attributes. In an object-oriented model, element types can be understood as a class, while elements are instances of the class. GIS middleware can be used to retrieve data from data sources for WMS servers and WFS servers. The WMS server receives requests and can retur

Therefore, the existing data models, whether it is an object model or a domain model, it is not the information of the real world, but the visualized parameters of some of its properties (basic, not completely). Therefore, problems such as system interoperability and Data Metadata cannot be well solved. Therefore, the concept of semantic GIS is proposed. Then, the relevant research and implementation are probably based on the relevant OGC specifications, esp

After talking for a long time, it seems that software is software, management is management, and management software is a strange term. Management + software should have been put together, but it cannot be combined. Therefore, management software must be competitive in terms of management methods. This is the only way to incre

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,

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. Using openlayers as the client does not have brows

In this exercise, you will implement the HTTP handler in the ASP.net Web application to return the GeoRSS feed. GeoRSS is a standard used to include geospatial data in RSS feeds that defines a specific format called GeoRSS GML that contains GML-formatted data in the feed. Client applications can subscribe to GeoRSS feeds in the same way that they subscribe to regular RSS feeds. You can easily import GeoRSS-
