TerraME is a development environment for spatial dynamical modelling that supports the concepts of nested cellular automata (nested-CA). TerraME uses a spatial database for data storage and retrieval. A spatial dynamic model is a model whose locations are independent variables. The outcomes of these models are maps that depict the spatial distribution of a pattern or of a continuous variable. TerraME enables simulation in two-dimensional cellular spaces. Among the typical applications of TerraME are land change and hydrological models.
This tutorial provides an introduction to the basic features of TerraME. For a full description, see [1]. The tutorial has four parts. In section 2, we present the TerraME architecture. In section 3, we present the basic commands of the TerraME programming language. In section 4, we show an example of using TerraME for hydrological modelling. In section 5, we show an example of land change modelling. Before using this tutorial, the reader should first install TerraME. Readers interested in an introduction to the principles of modelling should refer to [2] or [3].

Learning to live with spatial inconsistencies
Presentation
Spatial consistency defines admissible values of spatial data in database and information systems. Although this is a desirable and usually enforced property of geographic information systems, inconsistency in geographic information systems is not necessarily an exception, but a common situation we have to live with. Multiple examples are found around spatial global systems that access multiple and heterogeneous spatial local databases. This talk raises issues about inconsistency handling, which aims at manipulating data despite the fact that databases or information systems may contain inconsistency information. Instead of focusing on modeling and reasoning about consistency, it discusses what we can do when inconsistency exists. The talk takes a database perspective to define consistency in geographic information and concentrates on spatial constraints (topo-semantic and geometric constraints) that describe the valid states of spatial databases. The talk discusses traditional database approaches and their limitations in the context of geographic information. It also proposes to combine structural, functional, and semantics characteristics of spatial information for handling inconsistency.

Presentation
Networks of autonomous sensors can be embedded in a variety of spatial environments, such as airports, highway stretches, forests, or even the ocean. They enable the monitoring of environments for a wide variety of applications, from security to biological. Desirable properties for these networks include scalability, transparency to the users, and real-time response. Sensor networks with these properties exemplify the pervasive computing paradigm that is expected to become central in the 21st century. For many applications, the ability to query sensor networks in an ad hoc fashion will be key to their usefulness. Rather than re-engineering the network for every task, ad hoc querying allows the same network to process any of a broad class of queries, by expressing these queries in a variant of SQL. Transparency is achieved by giving the user a single point of access to the network (the server), and by focusing on query primitives that are independent of the exact number and routing configuration of the sensors in the network (to achieve scalability). In essence, the network appears to the user as a single distributed agent whose job it is to observe the environment wherein it is embedded, and to interact with the user about its observations.
The sensor network setting introduces novel aspects in each of the areas of database querying: query language, query interpretation, query evaluation, and query optimization. After an introduction to sensor network querying, we will focus on some of the novel issues introduced by the sensor network context, and discuss some technical results. We finish by exploring the possibility of merging geosensor network querying with spatial databases such as PostGIS.
