Spatio-temporal interpolation and fuzzy logic for GIS simulation of rural-to-urban transition.(geographic information systems)(Abstract)
April 1, 1999... ABSTRACT: When studying dynamic geographic phenomena such as rural-urban transformation in a raster GIS environment, information between two consecutive snapshot layers may not be available. This paper describes an application of fuzzy logic which enables the completion of unknown...
Representation and manipulation of moving points: an extended data model for location estimation.(spatio-temporal systems)(Abstract)
April 1, 1999... ABSTRACT: In this paper we introduce a classification for spatio-temporal systems based on the properties of the represented objects. Building on this classification, we assert that complex objects can be derived from simpler ones, following an evolutionary approach which starts with the...
"Time travel" visualization in a dynamic voronoi data structure.(geographic visualization)(Abstract)
April 1, 1999... ABSTRACT: It is now widely recognized that incremental changes of cartographic data evolving in space and time cannot be maintained easily within current GISs, and therefore visualization of such changes is limited to series of "snapshots" of cartographic data. Recent research on dynamic...
Conceptualizing space and time: a classification of geographic movement.(Abstract)
April 1, 1999... ABSTRACT: In an increasingly complex and interactive world, the need to study, manage, and understand the critical interface between physical and human environments is becoming more urgent, precipitating technological advancements in the dynamic spatio-temporal capabilities of geographic...
Dealing with Time
April 1, 1999... Maps are involved as soon as one decides to understand spatial relationships and patterns. Most maps limit themselves to a single snapshot in time. However, the study of geographical processes cannot be successful without considering time as well, because these events only happen as time...
