The notion of an object bearing information is central to the traditional situation semantics framework. Herein, this notion is extended to the realm of thematic maps as a vehicle for the formalization of their thematic content. Maps are the most acknowledged graphic representations of spatial phenomena. In the light of Situation Theory, we apply its evolution theory; Information Flow, to exami...

Thematic maps are nowadays widely used in a variety of research domains and human daily lives to depict and analyze spatial phenomena in reality. Though current Web-based GISs can already display thematic maps via internet, their content is nonetheless restricted to those maps already stored in databases. Naïve users, with limited cartographic knowledge and GIS software experience, can hardly s...

Tactile cartography has always been a niche topic, but even among tactile cartographers, little attention paid to thematic maps. Thematic maps are used in education and the lack of such materials makes it difficult fulfill particular subjects’ curriculums. In this research, we propose methodology for automatic compilation legible cartographically sound educational that bases on concept anchor l...

Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

Accuracy of thematic maps is identified as having two components: planimetric accuracy and data representation accuracy. The first is of only minor concern for thematic maps. Data representation accuracy, however, is at least as significant to map effectiveness as are the perceptual and cognitive aspects of map reading that have been given so much attention in recent years. The focus of the stu...

Comparison of thematic maps is an important task in a number of disciplines. Map comparison has traditionally been conducted using cell-by-cell agreement indicators, such as the Kappa measure. More recently, other methods have been proposed that take into account not only spatially coincident cells in two maps, but also their surroundings or the spatial structure of their differences. The objec...
