Hi I'll propose for QGis VisTrails plugin, here the text i'll be submitting as idea, do you have any feedbacks?
Idea: In scientific work-flow environments, Earth Observation/ Geospatial data, services and processes should be integrable together so that non-GIS users can utilise spatial data in their analyses (e.g. running statistical analysis, machine learning and numerical modelling processes). VisTrails is an open-source scientific work-flow and provenance management system developed at the University of Utah that provides support for data exploration and visualization. Whereas work-flows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, such as simulations, data analysis and visualization, very little is repeated---change is the norm. As an engineer or scientist generates and evaluates hypotheses about data under study, a series of different, albeit related, work- flows are created while a work-flow is adjusted in an interactive process. VisTrails was designed to manage these rapidly-evolving work-flows [vistrails.org] Many work-flows can include spatial data and would take a grate advantage of an integration between the QGIS in VisTrails. Furthermore, due to the use of PyQt in both projects, the fit should be natural. The aim is to produce a tool that will allow the following work-flow: - Allow a user to to fetch all the data layers s/he is interested in into Qgis. - Use the plug-in API to launch VisTrails as a plug-in - Give VisTrails access through Qgis API to all the currently loaded data layers in a data module. - Use other VisTrails modules to construct a work-flow - Have a VisTrails modules that places new generated or manipulated layers back into Qgis This approach would allow on one hand, Qgis users to have a model builder like environment where input data can be transformed through complex work-flows into new information. On the other hand this would allow seasoned VisTrails users to trigger the power of Qgis into their work-flows As a future work, this tool could be adapted as a VisTrails module so that it can directly be used from within VisTrails to trigger the Qgis spatial analysis power. ciao Marco -- Marco Bernasocchi www.bernawebdesign.ch skype: mbernasocchi _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
