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

• 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

• 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

• Schema translation definitions created with the use of

Matching Tables.

• These have to be generated by domain experts.

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

• 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

• 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.
