Taverna 2 Original Uploader Jorgejesus	Polygon buffer - Using pyWPS (v1) Created: 26/10/10 @ 16:10:14 \| Last updated: 26/10/10 @ 16:10:15 Credits: Jorgejesus License: Creative Commons Attribution-Share Alike 3.0 Unported License Basic example on how to integrate a Web Processing Service (WPS) using PyWPS's WSDL/SOAP The workflow will accept a GML file with featureCollection where polyon is described using gml:coordinate element structure. This GMl is easely generated with GDAL. The coodinate structure will be converted to WKT and used to create a polygon using shapely, the output will be a buffer polygon with a defined width. Output polygon will replace the orginal polygon and the existing XML will be return...

Taverna 2 Original Uploader Jorgejesus	Voronoi polygon generation using GRASS-GIS (v.voronoi) (v1) Created: 27/04/11 @ 16:18:17 \| Last updated: 27/04/11 @ 16:18:19 Credits: Jorgejesus License: Creative Commons Attribution-Share Alike 3.0 Unported License Generic example on how to deal with vectorial data. Major pitfall is the need to process ProcessOutputs using Xpath plugin. A random point file in GML 2.1.2 is sent to the v.voronoi service and after it is sent to a service that runs v.out.svg generating a SVG image that can be rendered in Taverna (need to set output to SVG image) Rating: 0.0 / 5 (0 ratings) \| Versions: 1 \| Reviews: 0 \| Comments: 0 \| Citations: 0 Viewed: 15 times \| Downloaded: 8 times Tags (7): gml \| grass \| netmar \| pywps \| svg \| vector \| voronoi	View Download (v1)
