GML2GML: Generic and Interoperable Round-Trip Geodata Editing – Concepts and Example
نویسندگان
چکیده
A range of tools offer possibilities for transforming geodata to SVG. We do not want to add yet another of such map generation projects, but investigate the general possibilities and restrictions for bidirectional XSL transformations between GML (Geographic Markup Language), SLD (Styled Layer Descriptor), and SVG. This is necessary in order to develop standards-based GIS applications supporting geodata-editing of geometry and attribute data. We explore the possibilities for a truly generic generation of these bi-directional transformations based on the GML application schema. This results in a cascade of several XSL transformations from the database schema to XSL code that finally transforms between GML data and SVG in both directions taking the style descriptions from SLD documents.

Development of a controlled vocabulary for semantic interoperability of mineral exploration geodata for mining projects
Semantic interoperability of mineral exploration geodata is a long-term concern in mining projects. Inconsistent conceptual schemas and heterogeneous professional terms among various geodata sources in a mining project often hinder their efficient use and/or reuse. Our study of a controlled vocabulary focuses on interoperability of mineral exploration geodata of different mining projects of a m...
متن کاملFramework - Specific Modeling Languages
We propose using framework-specific models to support the development of framework-based applications. Such models describe how framework-provided abstractions are used or implemented in the application code. Framework-specific models are expressed using framework-specific modeling languages (FSMLs), which capture framework abstractions as language concepts. In this paper, we present a concrete...
متن کاملNetwork-enabling GIS: issues, models and a review
Networking GIS tools and applications vary greatly in both function and architecture. In this paper, we will provide a framework to study the problems of networking GIS. GIS resources consist of geodata and geoprocessing capabilities. From the viewpoint of geodata sharing, it is observed that decoupling geodata and geoprocessing is necessary given the difficulty of integrating autonomous GIS sy...
متن کاملAn Interoperable IP based WSN for Smart Irrigation Systems
Wireless Sensor Networks (WSN) have been highly developed which can be used in agriculture to enable optimal irrigation scheduling. Since there is an absence of widely used available methods to support effective agriculture practice in different weather conditions, WSN technology can be used to optimise irrigation in the crop fields. This paper presents architecture of an irrigation system by i...
متن کاملDevelopment of GIS Interoperability Infrastructure in Local Community Environment
Increasing number of geodata producers and users in local community environment have expressed the need for the integration of geodata from distributed information sources and for interoperable GISs. The systems that own this data must be capable of interoperation with systems around them, in order to make access to this data to become feasible. The system also must deal with issues unique to g...
