On Wednesday afternoon (13-17h) March 26th, an OpenEarth workshop is organised, as part of the NCK days 2014 at UNESCO-IHE. The theme of this year’s session is ‘Zandmotor’.
The session will focus on the (newest) technical features of the server system and the actual data access (OPeNDAP and PostGIS/Geoserver) and vizualisation. Since the Zandmotor data is not publicly available yet, we will briefly discuss the procedure to get access to the data. We will practice with the same technology, using open data.
The session is organised by Kees den Heijer and Gerben de Boer.
- when: Wednesday March 26th, 2014 13.00-17.00h
- where: UNESCO-IHE, Delft
- sign-up: please register via http://nckdays2014.eventzilla.net/

Friday Nov. 1st: OpenGIS Workshop
This collection of standards is treated today:
netCDF exercise for Delft software days OpenGIS workshop - 1 nov 2013
WMS/KML exercise for Delft software days OpenGIS workshop - 1 nov 2013
- WMS manual: https://publicwiki.deltares.nl/display/OET/WMS+primer
- WMS into Google Earth manual: http://publicwiki.deltares.nl/display/OET/WMs+in+Google+Earth
- and here are a few urls to exercise with. These are the so called getcapabilities which always
append request=GetCapabilities&service=WMS to the base url until the ?-mark.
- Aerial images Minnesota
- World bathymetry maps:
- Numerical model in netCDF-CF rendered straight into WMS. These examples include time as dimension:
Monday Nov. 4th: Open Source Pre- and Postprocessing Workshops

May 30th an OpenEarth data sprintsession for Matlab, python, R is organized at request for WaLTER. We will show how to work in DatTube mode with data from the web:
- PostgreSQL with PostGIS for relational data (ecological data and in situ physical data)
- netCDF-CF-OPeNDAP for grid data. Deltares and NIOZ produce 200m resolution data (images below) for the (Western) Wadden Sea in the PACE project. This yields about 1TB of data, which you can only work with in web-based mode, it is too much to copy.
We start with a lunch lecture first, and then proceed with a hands-on afternoon
how to extract a relevant subset of the data deluge with Matlab, python and R scripts.
- when: Thursday May 30th, 12:00 lunch lecture with sprint session afterwards until 16:00.
- where: NIOZ, Texel. route: www.nioz.nl
- Sign-up: gerben.deboer<at>deltares.nl
- !! Bring your own laptop with your own Matlab/Python/R!!
A new NetCDF file with the JARKUS transects up to 2012 is now available via http://opendap.deltares.nl/thredds/catalog/opendap/rijkswaterstaat/jarkus/profiles/catalog.html
