Page History

The Deltares Data Portal is the starting place to find and publish spatial data sets. The portal facilitates the discovery, multiple usage and dissemination of spatial data. For questions on the data portal, please send an e-mail to deltaresdata@deltares.nl.

How to find data?

The Data Portal consists of two main ways to find data. Firstly, the Spatial Data Catalog. Here you can search for datasets available at Deltares using keywords.

Even though many important datasets will be made accessible by the catalog, there are many more spatial datasets available via external data portals. A categorical overview of the major external data portals has been added to this wiki. If you cannot find the data in the Spatial Data Catalog, look around there for portals that could help you.

How to create metadata

This is a boring process, but from the utmost importance to make your data discoverable via this portal. For that reason this page has been created where a short description can be found how to create a valid metadata file using the INSPIRE meta data editor.

How to work with spatial data?

There is an extensive collection of tutorials and short tech notes on analyzing, retrieving and creating various spatial data formats with different software tools on the Open Earth tutorials page.

Why not just Google the data?

You might wonder if Googling for the data of interest is a more efficient way to find the data. Unfortunately, the datasets contained within the Deltares Data Portal and external portals are often not indexed for Google, and will therefore not show up in your search results.
