Temporal relations in geographic information systems

Abstract: A workshop on temporal relations in Geographic Information Systems (GIS) was held on October 12-13, 1990, at the University of Maine. The meeting, sponsored by the National Center for Geographic Information and Analysis (NCGIA), gathered specialists on Geography, GIS, and Computer Science to discuss users' requirements of temporal GIS and to identify the corresponding research issues.

“…By this time, GIS software had become widely available and was being used in various institutional and academic fields.The same was true for image processing, used for analysis of aerial photographs and satellite images. There also was extensive conceptual work on how to handle time in GIS databases (Langran 1992), a conference on GIS and temporal data (Barrera et al 1990), and over 350 papers on spatiotemporal issues by almost 300 researchers (Al-Taha et al 1994). Other work dealt with underlying concepts and techniques of time and geography (Thrift 1977), visualization of geographic time-series data (Monmonier 1990), and treatment of time as a variable on maps (Vasiliev 1990).…”

“…Um banco de dados é um modelo da realidade por representar um conjunto selecionado de fenômenos da 13 natureza, que podem estar associados a diferentes períodos de tempo (passado, presente ou futuro) [19]. Modelagem de dados geográficos é o processo de discretização que converte uma realidade geográfica complexa em um conjunto finito de registros ou objetos de um banco de dados [20].…”
