Abstract
Spatio-temporal grid data form a core structure in Earth and Space sciences alike. While Array Databases have set out to support this information category they only offer integer indexing, corresponding to equidistant grids. However, often grids in reality have irregular structures, such as raw satellite swath data. We present an approach to modeling spatio-temporal regular and non-regular grids in a coherent manner, suitable for querying, transporting, and storing such data while remaining format independent. We briefly describe an implementation based on the combination of a relational and an array DBMS. Our model is currently under adoption as an international standard by OGC and ISO.
