I found the concept of Kepler pretty cool and although no real GIS functionalities were present at that time, I decided to give it a try.<br /> <br /> We have implemented new Kepler actors supporting some basic GIS functionalities using the <a href="http://geotools.codehaus.org/">GeoTools API</a>: <ul> <li>Bounding Box Selection</li> <li>WFS Requests</li> <li>Feature Merge Operations (geometry and attributes)</li> <li>GML Reader</li> <li>GML Writer</li> </ul> Those actors define the base for workflows dealing with spatial information processing. <br /> <br /> In one of our first workflows, we have developed a new actor implementing the Biomass Yield Model developed by the FH Eberswalden (<a href="http://www.fh-eberswalde.de/K1222.htm">Prof. Piorr</a> and <a href="http://www.fh-eberswalde.de/de/Forschung/Projekte/Bioenergie/Team/E3363.htm">S. Brozio</a>). The workflow takes as parameter a bounding box and computes the yield based on the information retrieved from different WFS Servers (soil quality, temperature, precipitation…).<br /> <br /> We are currently working on further GIS functionalities like for example JSON support and some more advanced operations on Features. ctuot <a href="http://ctuot.twoday.net/topics/Kepler">Kepler</a> Copyright © 2007 ctuot 2007-08-03T12:53:00Z Search this site: q http://ctuot.twoday.net/search
