Workflows (5)

Workflow Polygon buffer - Using pyWPS (1)

Thumb
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...

Workflow Voronoi polygon generation using GRASS-GIS... (1)

Thumb
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)

Workflow GRASS-GIS orchestration using pyWPS (2)

Thumb
Generic workflow that run r.watershed, with auxiliary services: r.math and geotiff2png. Watershed accumulation is calculated from DEM using r.watershed, the accumulation result is then filtered using r.math with equation:output=(if(a>10,a,null())) Generic workflow that run r.watershed, with auxiliary services: r.math and geotiff2png.
