Summary
Although agriculture has always been considered as a »transportation industry against its will« during the last decades structural changes in agriculture intensified agricultural transportation processes. Despite the importance of the subject »transportation in agriculture« – apart from local surveys and expert’s opinion – detailed, reliable, and comprehensive information about local transportation distances or the quantity of area that can be accessed by a single road segment is missing. This paper presents a tool and concepts for a high-performant, detailed and especially comprehensive assessment and analysis of all agricultural farm-field transportation processes. Analyses are both based on nationwide available geospatial data from the Agricultural Administration as well as geospatial data from the ordnance survey. Apart from processing large amounts of data major challenges were the harmonization and integration of heterogenous geospatial data from different sources in one single comprehensive semantic data model.
