Under development

The old GCW Data Portal is available at http://gcw.met.no. This portal is still under development and active content management has yet not started. The Global Cryosphere Watch catalogue is yet not considered an operational service. It is populated with metadata harvested from a number of contributing data centres, but data remains in the original location and are served through the interfaces supported by the originating data centre.

The concept of metadata

GCW Portal metadata are divided in 4 categories which are briefly described in Table 1. Among these 4 categories, data providers or supporting data centres are supposed to provide 3 of them. Further below in this document, there are recommendations on how to provide these.

Contributing data centres

An overview of the contributing data centres is provided in the illustration below. Not all data centres are fully integrated, but discussions on how to integrate have been initiated.

About the GCW Data Portal

The GCW Data Portal, or catalogue, is dedicated to data management and to providing specific information on datasets. The data management component is an enabling service in the sense that it identifies relevant datasets and their locations and provides an interface that can be used in the evaluation of GCW data and products. The portal will support simple visualization (generation of maps or diagrams like time series) and transformations such as reformatting and re-projection of data, if the data are served through the appropriate interfaces and forms.

GCW Data Management

Any issues related to GCW Data Management will be handled through this project.
