towards the geospatial semantic web

I know that it has been a while since my last blog but so many things to do and so little time.

We have been working a lot on our Biomassplaner (RAPR) which I have already briefly presented in a former story. One of the most important steps in research and development is the evaluation.
Some weeks ago, we had the opportunity to evaluate our software with 14 farmers. Each of them gave us some electronic documentation of their fields downloaded from the public service "FLächeninformationen Online" (FLOrlp). The documentation goes through our Biomassplaner which delivers a prognosis for the yield based on the model (Biomass Yield Model) developed by Professor Piorr and Sybille Brozio at the University of applied sciences Eberswalde. Our Biomasseplaner offers both some advanced geographical and table based visualization. We also developed several export plug-ins for Goolgle Earth and Microsoft Excel.
During the evaluation, we were interviewed by a journalist working for a regional newspaper “NAHE-REPORT” and finally we got a whole page describing our current work.

The first feedback we got from our users is more than positive and we are now working on a first release. I hope I will be able to blog soon about RAPR going productive.

AT last, just some few words to thank my project partner Dr. Wolfgang Schneider from Dienstleistungszentrum Ländlicher Raum who initiated the project.

I have just finished uploading two videos in Youtube both demos of the tools we have implemented in the RAPR project. The videos are commented but in German, sorry for that but it is always difficult to maintain different versions. Since I am also not convinced about the quality of the videos (thx Youtube), I will render new Videos with English comments and store them on my Homepage.

1. DFKI - Projekt RAPR - Demo - Logistikplaner
2. DFKI - Projekt RAPR - Demo - Biomasseplaner

The Logistikplaner is kind of a mashup based on Adobe Flex 3 and GoogleMaps. The Logistikplaner can be used for example to determine the best position to build a plant for the production of Biogas optimizing the distance to specific fields minimizing the transport distance (routing distance).

The Biomasseplaner has access to the soil quality and the weather information and uses the Biomass Yield Model developed by the FH Eberswalde to compute the yield on given fields depending on their crop rotation. The tools offers a hight interaction with the user to correct results and also supports export in Open Document Format (ODF).
The Biomasseplaner is based on XForms and OpenLayers.
One objective of the IVIP project is to deploy those tools in a productive environment.

IVIP stands for "intelligent integration of source of information for business specific, location based planning for the production of energy crops" (German: Intelligente Vernetzung verteilter Informationsquellen zur betriebs- und standortspezifischen Planung der Energiepflanzenerzeugung).

Decision making in crop production is essentially stamped by location-based or more precisely by space-oriented information or also by particular location driven situations. This is for example the case for the production of food and renewable raw-materials. Indeed, the cultivation of bio-raw materials can in certain regions lead to severe irregularities in the configuration of crop rotations. According to this fact, farmers and regional experts producing renewable raw materials mostly rely on new spatial-data-oriented decision making tools.

Within the RAPR project, DFKI conducted a feasibility study in Rhineland-Palatinate to show the benefits of a location-based biomass-planer using digitalized geographic information about ground allocation (FLOrlp) and soil quality (LGB). This project resulted from the successful cooperation of the different geologic and plant cultivation consulting facilities in Rhineland-Palatinate.

With the IVIP project, we intend to fill in the gap between the bid of information from LGB and the valuable location-based consulting services of DLR/ZEPP/ISIP in Bad Kreuznach by using the Web-based Spatial Decision Support System prototype developed in RAPR.

Last Wednesday, I had the opportunity to present the RAPR project at the German Federal Ministry in Bonn. But what is exactly the RAPR project?
Spatially Oriented Rule Based System for a Resource and Production Management of Raw Bio-Materials (German RAPR: Raumbezogene Regelwerkzeuge fuer ein Produktions- und Ressourcenmanagement von Biorohstoffen).

A DFKI Kaiserslautern - Knowledge Management - project for the region Rhineland-Palatinate in collaboration with John Deere and Agricultural Management Solutions (AMS) in Zweibruecken. RAPR aims to develop a rule-based prototype to process space-oriented agricultural knowledge in order to economically grow organic commodities. The prototype is planned to be tested while supporting the existing advisory service for production and resource management. After its completion the system will be available as open source software.
We already have two working prototypes, the Logistic-Planner and the Biomass-Planner. For copyrights problems, we are not allowed for the moment to put those prototypes online. However, I will write blogs describing both tools in details with Snapshots or Videos.

I believe the presentation went quite well and people were impressed by the demos. We have already got positive feedback and I hope this will continue.

The RAPR project was successfully closed on April 2007. I am now working on the IVIP project, more information in my next Blogs.
