Introduction

• Dataportal

– Past: catalogue of metadata

– Since 2008: data portal

• Different sources

• Storage & harvesting of data & GIS layers

• Higher visibility for data providers/originators

• Access data at different levels

– Metadata level (datasets description)

– Data visualisation

– Download average or original data

Metadata & INSPIRE

• Availability of metadata, uniform standard

• Harmonization of geoinformation

• Efficient access to geoinformation

• In metadata link to keywords other

systems developed by VLIZ – WoRMS

– Marine Regions

– IMIS

Problems and solutions

Problem Solution

Harvesting of metadata from

GeoServer into GeoNetwork

Create new metadata descriptions

instead of harvesting

Time consuming effort

Lack of information of received GIS

layers

Metadata & attributes information

Contact data provider, search for

publication, decode and create

metadata

Interface of GeoNetwork does not fully

meet the INSPIRE Directive

Using INSPIRE Metadadata editor,

save as xml and import in GeoNetwork

Definition of the metadata fields

Scale, code, …
