Agriculture plays an essential role in restructuring and country planning. However, the agricultural world is under economic pressures that affect the efficiency of landowners. To ensure good productivity, the farmer needs his land to be spatially well organised and well equipped. To use the agricultural land most efficiently, it is important first to understand the area by collecting together ...

Geographic information systems (GIS) have developed in response to a range of needs, and provide highly structured environments for working with particular classes of information. The environment and structure of a GIS is defined by its data model; the paper reviews the basic data models of GIS. The needs of discrete transportation modeling have led to a number of extensions of the basic data m...

It is 20 years since the term “geographic information science” was suggested to encompass the set of fundamental research issues that surround GIS. Two decades of GIScience have produced a range of accomplishments, in an expanding literature of research results as well as in the infrastructure of research. Several themes are suggested for future research, based both on gaps in what has been acc...

This paper presents five properties that are true of the resolution of (geographic) data, and discusses their implications for Geographic Information Science (GIScience). It argues that resolution is (i) always present in data, (ii) representation-dependent, (iii) positively correlated with accuracy, (iv) positively correlated with data volume, and (v) more specific than granularity. These stat...

Terraced areas have existed in Italy since ancient times, and they continue to be characteristic elements of the cultural identity of the country. The progressive abandonment of rural areas and farmland that began in the 1960s has led to the disintegration and disappearance of many terraces, representing one of the problems connected with the deterioration of the historic Tuscan agricultural la...

The paper introduces an overview on the researches we are currently carrying out on the integration of semantic aspects in Geographical Information Systems. Through an overview on the activities in the context of a project concerning the study of Bronze Age settlements in northern Italy, the paper shows how issues concerning semantics and GIS are currently faced to define an innovative and inte...
