The process of geodata harmonisation should create the possibility to combine data from heterogeneous sources into integrated, consistent and unambiguous information products, in a way that is of no concern to the end-user.
Users shall be enabled to formulate their demand for geospatial data, involving requirements on the format, spatial reference system, data schema or language of the data. Based on a formalised description of the demand, information shall be provided to the user that is directly usable, i.e. that meets the requirements. The aim of this open source project is to provide the software for achieving or at least supporting this vision. The software can be divided into the following main categories: Data Harmonisation Toolkit, Framework for Service Integration, and Processing Components / Transformation Services.
1. Data Harmonisation Toolkit
The data harmonisation toolkit consists of a set of tools with graphical user interfaces that enable users to perform different tasks such as conceptual schema modelling and mapping.
2. Framework for Service Integration
The Framework for Service Integration consists of software components that enable users to publish geodata and to consume geodata via OGC-conformant interfaces, harmonised and transformed to their requirements. It consists of the following services:
3. Processing Components / Transformation Services
The framework is able to handle processing services that are encapsulated within web services that conform to the OGC Web Processing Service standard or processing services that are directly implemented on the platform on which the Mediator Service is deployed. There are several harmonisation processing components already implemented (or about to be implemented) as part of the open source framework:
The first release of the Open Source Software for Geodata Harmonisation was published in April 2009. The development is continued in the EU-project HUMBOLDT. This open source release is the first major step towards the creation of an Open Source Community for Geodata Harmonisation Software and the HUMBOLDT consortium invites developers to test the design and expandability of the framework. Suggestions and contributions are highly welcome.
The Open Source Software is published under GNU Lesser General Public License version 3 (LGPL v3).
