Résumé(disponible en anglais seulement)
A query framework for spatial targeting within a 3-D GIS software environment is introduced. Input to a query consists of parameters relevant to the query type together with a set of Common Earth Modelling objects represented as point sets, polygonal lines, surfaces, and grids or a region set (sub-set) within such objects. The result of a 3-D GIS query is a subset or region within each of the input objects that consists of nodes or grid cells where the query criteria was satisfied, i.e., found to be true. We provide example scenarios, drawn from mineral exploration, where 3-D queries are used to guide spatial targeting within a near-mine or regional map scale setting. This development focuses on queries relevant in the 3-D data integration and interpretation stages of mature geological model development as well as early analysis, typically undertaken before a fully partitioned and attributed 3-D topological model is built.
