In this paper, fuzzy-based multisensor data fusion is studied and an iterative fuzzy classifier is proposed. Obtained results are given as a set of two maps: a thematic map, and a confidence map (a classification certainty map representing the degree of certainty in the thematic map). The application of this classifier using ERS-1/JERS-1 SAR composites is shown to very promising.

This study presents a method used for predicting the air temperature distribution in an urbanized area from the surface temperature of trees. A strong trend of urbanization can be observed whole over the world (United Nations Centre for Human Settlement, 1996). It is well known and documented that urbanization can have significant effects on local weather and climate (Landsberg, 1981). One of t...

In this paper we examine the visualisation of multiple variables in thematic maps by using the third dimension. Three cases illustrate the potentials and limitations for three-dimensional visualisations of multivariate datasets. After examining these examples, we reflect what should be considered carefully when creating this kind of maps. Maps making use of the third dimension can help to visua...

In this study, associations between alexithymia, interpersonal problems, and cognitive-structural aspects of internal interpersonal representations were examined. Alexithymia was measured using the Toronto Structured Interview for Alexithymia (TSIA) and the 20-item Toronto Alexithymia Scale (TAS-20). To measure interpersonal problems, the dominance and affiliation dimension scores of the Invent...

In the field of electronic publishing, encyclopedias represent a unique sort of text for investigating advanced methods of navigation. The user of an electronic encyclopedia normally expects special methods for accessing the entries in an encyclopedia database. Navigation through printed encyclopedias in the traditional sense focuses on the alphabetic order of the entries. In electronic encyclo...

In this paper, we describe a segmentation technique that integrates traditional image processing algorithms with techniques adapted from knowledge discovery in databases (KDD) and data mining to analyze and segment unstructured satellite images of natural scenes. We have divided our segmentation task into three major steps. First, an initial segmentation is achieved using dynamic local threshol...

The starting point for this article is the fact that each spatial object i is characterized by three coordinates: x (latitude), y (longitude) and zi(by tradition elevation). The discussion is organized around three axes. First, the author reviews some of main problems encountered when representing a volume (ellipsoid) on a plane (map). Second, some elementary principles of cartography are discu...
