CartoTalk Ivana Brkovic

We are happy to welcome Ivana Brković, Ph.D, of the University of Zagreb to our colloquium CartoTalks.

Semantics of space in the 17th century Ragusan literature

The presentation deals with representation of space in literary texts of the 17th century Ragusan authors. Following spatial turn in contemporary humanities and social sciences, literary space is approached as a social and cultural product. Focusing on exemplary literary works, it will be shown that literary spaces in the given texts invoke multiple meanings, which are generated by different discourses (historical space, social space, (geo)political space, religious space etc.). Implying multiple demarcations, representation of space in the texts of the Ragusan authors implies the different concepts of collective identities. Preferential space(s) of identity/alterity reveals the auto/raguso/centric perspective and, especially, the 17th century political (and ideological) discourse of the Ragusan aristocracy.

Ivana Brković, Ph.D, is a Senior Assistant at the Department of Croatian Language and Literature (University of Zagreb, Faculty of Humanities and Social Sciences), researching and teaching Early Modern Croatian Literature.

She also works on the Research Project “Imagological research of the 16th-19th century Croatian literature”.  In February 2011, she defended her PhD thesis on “Semantics of space in the 17th century Ragusan literature”.

8th International Symposium on Location-Based Services

lbs2011_logoThe 8th International Symposium on Location-Based Services took place at Vienna University of Technology from 21 to 23 November 2011. We are happy that after its initiation at TU Vienna in 2002, the conference traveled around the world to come back “home” now.

CartoTalk Rene Sieber

Wir freuen uns, René Sieber, Projektleiter Atlas der Schweiz und Mitarbeiter am Institut für Kartografie und Geoinformation (IKG) der ETH Zürich in unserer Vortragsreihe CartoTalks begrüßen zu dürfen:

Vom proprietären Atlassystem zu einer offenen 3D-Webatlas-Plattform

Die grosse Popularität von geografischen Daten und Anwendungen bietet Atlas-Autoren die einmalige Chance, neue Nutzergruppen anzusprechen und in die Umsetzung des Projektes einzubinden. Hierzu müssen die digitalen Atlanten indessen neue Wege einschlagen, um gegenüber frei verfügbaren, kostenlosen Kartendiensten, Geoportalen und Virtuellen Globen konkurrenzfähig zu bleiben. Eine Analyse aktueller Geovisualisierungsprodukte hat gezeigt, dass die Mehrzahl der heute betriebenen Anwendungen primär für den Einsatz im Web konzipiert ist. Die Attraktivität solcher Anwendungen basiert auf dem unmittelbaren Nutzen im Alltag, der Aktualität der Daten und den integrativen Möglichkeiten. Anwendungen mit Virtuellen Globen bestechen zudem durch die intuitiv navigierbare Dreidimensionalität. Die inhaltliche und kartografische Qualität dieser Applikationen ist hingegen sehr heterogen; zudem fehlt eine atlasspezifische Funktionalität. Die grosse Herausforderung und das Ziel für die Zukunft ist es, eine Webatlas-Plattform zu entwickeln, welche hochqualitative 2D- und 3D-Visualisierungen sowie einen kollaborativen, offenen Zugang in Bezug auf Datenintegration und Programmerweiterungen unterstützt.

Als Lösungsansatz wird das Konzept der Atlas-Plattform-Schweiz (APS) vorgestellt, welche auf einem Virtuellen 3D-Globus basiert, mit beliebig grossen Datensätzen umgehen kann, sowie in der Funktionalität durch Plug-ins erweiterbar ist. 3D-Ansichten und klassische 2D-Karten sollen mittels einer einheitlichen technologischen Grundlage und Datenstruktur aufgebaut werden. Auf Basis dieser Webatlas-Plattform wird in einem mehrjährigen Projekt die neue Produktelinie ATLAS DER SCHWEIZ – ONLINE und ATLAS DER SCHWEIZ – MOBILE entwickelt, welche interaktive, thematische Kartografie mit einem 3D-Atlas verknüpfen wird.

Als Zusatznutzen dieser Plattform können externe Atlas-Autoren ihre eigenen Atlasprojekte realisieren, indem sie einzelne Module oder Funktionen der APS selektieren, kombinieren, erweitern und mit einem angepassten grafischen User Interface zu einem eigenständigen Produkt fertigstellen.

CartoTalk Miljenko Lapaine

We are happy to welcome Prof. Dr. Miljenko Lapaine of the University of Zagreb to our colloquium CartoTalks.

Mollweide Projection and the ICA Logo

Pseudocylindrical map projections have in common straight parallel lines of latitude and curved meridians. Until the 19th century, the only pseudocylindrical projection with important properties was the sinusoidal or the Sanson-Flamsteed projection. The sinusoidal has equally spaced parallels of latitude, true scale along parallels, and equivalency or equal-area. As a world map, it has the disadvantage of high shear at latitudes near the poles, especially those farthest from the central meridian.

In 1805, Karl Brandan Mollweide (1774–1825) announced an equal-area world map projection, aesthetically more pleasing than the sinusoidal, because the world is placed in an ellipse with axes in a 2:1 ratio and all the meridians are equally spaced semiellipses. The Mollweide projection was the only new pseudocylindrical projection of the nineteenth century to receive much more than academic interest.

The lecture will start with a brief description of Mollweide’s life and work. The formula or equation in mathematics named after him as Mollweide’s formula will be shown, as well as its proof “without words”. Then, the Mollweide map projection will be defined and formulas derived in different ways to show several possibilities leading to the same result. The inverse equations will be derived as well.

The most important part in research of any map projection is the distortion distribution. That means that the talk has to continue with the derivation of formulas enabling us to gain insight about the linear and angular distortion of the Mollweide projection.

Finally, the ICA logo will be used as an example of a good application of the Mollweide projection. The talk will finish with a comparison of some similar map projections. The map painted on the ICA flag is going to be mentioned. It seems the map was not produced according to the Mollweide projection and is different from the ICA logo map.
