Resumen:
Multilevel modeling is an approach to model-driven
engineering (MDE) in which the number of metamodel levels is
not fixed. In this paper, we present and discuss the application of
multilevel software modeling to the development of geographic
information systems (GIS), and its potential benefits. Different
GIS applications may provide different features and functions,
but they all share a set of common concepts (regarding spatial
data types, operations, services, etc.), common architecture, and
a common set of technologies. Although we do not present a
complete set of models, we present representative parts of that
set (spatial networks, territory decomposition, and trajectories)
that, when compared with previous work on MDE applied to
GIS, support our proposal that multilevel modeling can provide
more benefits to GIS development than just applying a more
traditional two-level MDE approach.
