The completeness and versatility of spatial data models and associated operations serve as the foundation of any GIS. The raster data model and the cartographic modeling framework provide the representation and operations for analyzing geographic fields. The current GIS raster data model and cartographic modeling operations are limited in that all the attributes measured at each location in fields are scalar quantities. This research proposes a new raster data model for representation and analysis of spatially distributed vector measurements. It extends the cartographic modeling framework by identifying new operations specific to vector fields and by extending existing operations to vector fields. Applications of the data model and operations are also provided.
