A multidimensional data model and OLAP analysis for soil physical characteristics

The paper describes the construction of a multidimensional data model intended for the analysis of soil physical properties. The data from the model are provided by two agricultural soil/land databases. Based on the multidimensional data model we build an OLAP cube called AGRISOL_FIZ. The "cube" accepts queries on several dimensions and hierarchies, including land uses, soil types, soil textures, counties, micro-zones, physical geographical units and relief forms. Note that OLAP is a flexible tool that is suitable for complicated analyses of multidimensio nal data. The analyses are done in a screen -efficient way. We give two examples with OLAP operations on the cube AGRISOL_Fiz.
