GML has become an accepted and easy-to-understand standard for the exchange of spatial information. Therefore, the conversion of other GIS data into the GML format has broad practical value and market prospects. In the near future, a large amount of spatial information will exist in the GML format, so that people can easily share and exchange spatial information.

In gml3, temporal information can be expressed. The time pattern in gml3 extends the core elements of GML to include elements that can describe the time features of geographic data. The purpose is to describe and define the structure of a language, that is, to provide a method for describing the history of a dynamic, element-based time model, these structures are expressed in XML mode or the lifecycle of a collection of elements. The basic time-space

Comparison of GML, SVG, and VML Comparison of GML, SVG, and VMLGML, SVG, and VML are both Markup languages based on XML that can be used to describe vector graphics. They are both XML word lists and their syntax is not hard to understand, but they all have their own purposes and features, the following is a brief introduction.

The conversion process from data in the shapefile format to data in the GML format can be divided into two major steps: one is to obtain data based on the data in the shapefile data documentation, and the other is to construct the data in the GML format according to the GML standard. From the analysis of the shapefile data format and the

GML is a complex standard. The content in this article is based on ogc gml 3.1.0. It contains a lot of content, except the conventional two-dimensional Vector GIS information, it also includes complex targets, topology information, three-dimensional targets, temporal information, geographical coverage, annotation symbols, spatial references, metadata, and raster data.

GML (Geography Markup Language) It is an XML-based spatial information encoding standard proposed by OpenGIS Consortium (OGC) and has received strong support from many companies, such as Oracle, galdos, Mapinfo, and cubewerx. Using GML, the encapsulated geographic data and graphic interpretation are clearly separated. GML uses text to represent Geographical In

Theoretically, we want to use XQuery to connect spatial data. Use GML to store space data. Connect to GML using XQuery The existing database platforms and 3 s platforms differ in the storage of spatial data in spatial databases. However, all major relational databases support XML You can consider using GML to represent spatial data in a relational database.

In my previous post, I introduced Oracle spatial to convert Geometry to a gml string (http://www.cnblogs.com/likehua/archive/2012/10/18/2730172.html), which mainly uses three functions get_wkt (), sdo_util.TO_GMLGEOMETRY (), and to_char (). In fact, there are no problems with these three functions, just like the test in the previous blog. However, if the Geometry is very large (that is, it has many points), The to_char function will report an error. B
