Rte objectives l.jpg
RTE Objectives

  • The main objectives of the RTE are to:

    • Demonstrate the creation of harmonised data products

    • “on-the fly” from existing data sets

    • Allow users to test and evaluate the data products (and hence the specifications)

  • Achieved through interactive website that:

    • Provides access to background information

    • Allows harmonised vector data products to be generated through the use of “schema-translation” software and WFS.

    • Allows harmonised raster data products to be generated through the use of a WCS.

    • Allows harmonised data products to be compared to the input datasets

  • Additional testing requires external additional GIS processing

Main software components l.jpg
Main Software Components

  • Oracle database 10g

  • Snowflake Go Publisher for:

    • Schema Translation

    • WFS

  • Minnesota Map Server for WMS and WCS;

    • and cascading to the WFS for GML portrayal

Testing l.jpg
Testing

  • Three Themes

    • Hydrography (i.e. catchment area polygons; river and lake segments)

    • Landcover (i.e. RISE defined scheme based on CORINE classification)

    • Elevation (i.e. uniform grid of Digital Elervation Model (DEM)

  • Two Test Areas

    • Vindan (East Sweden)

    • Enningsdalsalven (Swedish Norwegian Borders)

Use of matching tables l.jpg
Use of Matching Tables

  • Schema translation definitions created with the use of Matching Tables.

  • These have to be generated by domain experts.

Proposed data product testing l.jpg
Proposed Data Product testing

  • Via the website:

    • Display pre and post harmonised data products

    • Display data with other layers to demonstrate consistency

    • Capture data products for additional external testing

  • External testing:

    • Hydrography: network analysis

    • Landcover: generate % landcover for given catchment

    • DEM: Carry out Thalweg analysis

  • RISE-User Meeting planned for 26th June.

Current status l.jpg
Current status

  • Hardware and software installed.

  • Website created

    • http://www.pinkbox.space.qinetiq.com:8080/rise

    • For username and password please contact wyn cudlip

  • Test data ingested and example harmonised Data Products produced.

  • Example hDPs passed to externals for further testing.

  • Further work:

    • Improve website

    • Improve hDP creation process

    • Carry out further product testing

    • Document results

Conclusion l.jpg
Conclusion

  • RISE RTE can produce hDP “on the fly”.

  • In general, “missing information” can be created automatically without any database intervention.

  • In practice, the degree of automation will depend on how much information is missing from the input existing datasets.

  • External testing of hDP is being established.

  • Scalability issues (i.e. to cope with national datasets) needs to be thought about.
