i.nl

ADAGUC is about…

� Connecting atmospheric- and geosciences

� Atmospheric datasets in GIS systems

� Open standards � OGC� Web Mapping Service – For visualization

� Web Feature Service – To retrieve vector data

� Web Coverage Service – To retrieve raster data

� Knowledge & technique dissemination

NetCDF4 as data carrier

� Joint project between Unidata and HDF Group

� NetCDF 4 uses HDF5 as the storage layer of NetCDF

� Programming interfaces are backward compatible with the netCDF3 programming interface

NetCDF3popular, simple, lots of tools,

multiple implementations

HDF5powerful, high-performance,

storage efficiency, extensibility

NetCDF4

Best of both formats combined!

i.nl GDAL/OGR drivers

Open source translator library for raster geospatial data formats

Used in many software productsUMN MapServer, GeoServer, Quantum GIS, ArcGIS, GRASS, OpenEV etc..

GDAL - Geospatial Data Abstraction Library

� Access raster data

OGR - Simple Feature Library

� Access vector data

GDAL/OGR extensions for the ADAGUC format standard are available:

� Obtaining the real data through OGC services or the original ADAGUC (NetCDF/HDF5) files

� WFS or WCS ?

� WebGIS client selects the appropriate service depending on the datatype (raster/vector)

� WCS – obtain optimal parameters:

� Predefined bounding box, columns, rows and cell size

� No resampling/interpolation

User is always free to adjust the parameters

� User must select his favorite (GIS) format

Summary

� Product standard is stable.

� Much experience gained with GDAL/OGR, NetCDF/HDF5, INSPIRE, OGC, UMN MapServer

� Portal and services are ready:� Satellite, model, and radar datasets are

available and more will follow.

� Next challenges:

� Start using catalogue services (CSW).

� Data policies, operational status.

� 4 dimensional data.

� Client applications should work on supporting the OGC standards.
