In the early twentieth century, American suffragists used ‘‘a suffrage map’’ showing the spread of women’s suffrage on posters, pamphlets, and broadsides. The map was part of a shift in tactics used by the suffrage movement: leaving the parlours and taking to the streets, the suffragettes were claiming public space. This article explores the verbal and graphic rhetoric of these persuasive maps,...

This was another stimulating and enjoyable conference of the Groupe des Cartothécaires held in the impressive gravity-defying new extension to the Kongelige Bibliotek. The papers and issues discussed ranged from the everyday and practical to the abstract and theoretical, from historical cartography to future digital glints in the eye, and this report is inevitably a personal and simplified acco...

Recent developments in computer science have influenced the use of Geo-imagery by expert groups and the general public. The processing methods of remote sensing results and photogrammetric recording have became more accurate, effective and the work flow is accelerated. The results, in general, are often used for engineering, documentation purposes and for the communication of environmental syst...

Despite common belief, software engineers do not spend most time writing code. It has been shown that an approximate 50–90% of development time is spent on code orientation, that is navigation and understanding of source code. This may include reading of local source code and documentation, searching the internet for code examples and tutorials, but also seeking help of other developers. In thi...

We aim at finding a set of timing parameters for which a given timed automaton has a “good” behavior. We present here a novel approach based on the decomposition of the parametric space into behavioral tiles, i.e., sets of parameter valuations for which the behavior of the system is uniform. This gives us a behavioral cartography according to the values of the parameters. It is then straightfor...

The creation of maps is the art and science cartography, which has been a vital part human history for millennia. Maps have used to represent world around us since prehistoric cave drawings through contemporary satellite imaging, assisting in navigating, exploring, comprehending our surroundings. Cartography changed significantly over past few decades as result technological advancements availa...

In this article, we present a new method of automatic 3D urban cartography in which different imperfections are progressively removed by incremental updating, exploiting the concept of multiple passages, using specialized functions. In the proposed method, the 3D point clouds are first classified into three main object classes: permanently static, temporarily static and mobile, using a new poin...

In the literature on complexity theory it has been noted that the increasing interdependence, non-linearity, and adaptiveness of social and other systems require forms of representation that can accommodate such complexity. In this essay I argue for examining the possibilities of cartography (mapmaking) in and of educational theory and research. Cartography offers alternative forms of represent...

Influenza viruses have been responsible for large losses of lives around the world and continue to present a great public health challenge. Antigenic characterization based on hemagglutination inhibition (HI) assay is one of the routine procedures for influenza vaccine strain selection. However, HI assay is only a crude experiment reflecting the antigenic correlations among testing antigens (vi...

It is impossible to specify with any precision when the "cartography program" originated at Penn State. From the department's start in 1945, Penn State geography has been rooted in maps and mapping. Maps have been viewed as both an integral part of the research process and the result of research, rather than simply as a summary of research findings. Recent work using spatial adaptive filtering ...
