Vaklodingen bathymetry data in OpenEarth:

1. Raw data + scripts (ascii + Matlab)
   • Raw ascii data + Matlab tools for conversion to netCDF
     https://svn.oss.deltares.nl/repos/openearthrawdata/trunk/rijkswaterstaat/vaklodingen/ (register at oss.deltares.nl)
2. Standardized data (netCDF on OPeNDAP). The netCDF files can be viewed and analyzed interactively with Ucit.
   • 2020 release: production is available via https://opendap.deltares.nl/thredds/catalog/opendap/rijkswaterstaat/vaklodingen_new/catalog.html. 
   • 2012 release: production: http://opendap.deltares.nl/thredds/dodsC/opendap/rijkswaterstaat/vaklodingen/catalog.html, processed with the new nc_gen in Matlab OpenEarthTools. This new release now has 80% (37/46 items) conformity with ISO meta-data standards with ncISO (we'll aim for more in release 2013 next year)
   • 2011 release: production: (processed with with the generic nc_multibeam netCDF tiles toolbox with Rijkswaterstaat vaklodingen tile configuration in Matlab OpenEarthTools). This old release has been deleted but can be regenerated any time with the old version of the processing chain as kept in SubVersion.
   • 2010 release: production: (generated with abandoned dedicated processing line in Python). This old release has been deleted but can be regenerated any time with the old version of the processing chain as kept in SubVersion.
3. Visualized data (kml) (only 2012 release)
   • Vaklodingen overview (with links to OPeNDAP): http://kml.deltares.nl/kml/rijkswaterstaat/vaklodingen_overview.kml
   • All Vaklodingen data as tiled pngs, the same technology that Google Earth uses for all aerial imagery: http://kml.deltares.nl/kml/rijkswaterstaat/vaklodingen.kml
