“There are hot spots of wrecks in places I did not expect”
What can shipwrecks of the 19th century in the Indian Ocean tell us about the climate of the past? And what can the records of these wrecks tell us about climate knowledge production? Debjani Bhattacharyya, Professor for the History of the Anthropocene at UZH, explores these questions.

Was sagen Volksmusik-Sendungen über uns aus?
Volksmusik-Sendungen sind mehr als nur Unterhaltung. Was sie über die Gesellschaft, Kultur und Heimat aussagen, dem geht ein SNF-Forschungsprojekt nach. Wir vom GIS Hub durften fürs Projekt eine Karte der Sendeorte erstellen.

How to create a map layout?
You need a map for a paper or a presentation? This QGIS tutorial shows you how to create a layout for your map with a title, a legend, a north arrow, a scale etc., which you can export as image or PDF.
Comparing two sets of point data (III)
When we count points of two data sets per cell, we can compare their densities. Generating Chi expectation surfaces allows us to compare actual with expected densities. To come back to our geographical names with “wald” in Switzerland, we could compare if these names are over- or underrepresented compared to all the geographical names.
Working with point data (II)
This is part II of the point data tutorial for QGIS. It teaches you how to create a grid to calculate a density surface, that is to count the points per grid cell.
Selecting point data in QGIS (I)
Let’s assume: You have imported point data into QGIS and want to analyse it further. This short tutorial shows you step by step how you can filter your dataset based on an attribute or on the spatial location.
How to start a new project in QGIS?
You have spatial data and know what you want to analyse, but how do you start? This short tutorial gets you started and guides you step by step through a project setup.
Using GIS to tackle the SDGs
How do companies, NGOs and public institutions monitor their progress towards the sustainable development goals (SDGs), and how can GIS software contribute? Five speakers provided answers from different perspectives at the event “Using GIS to tackle the SDGs”, organized by the GIS Hub and ESRI Switzerland.
“I love to see my data on a map”
As a dialectologist, Carlota de Benito Moreno is interested in how linguistic features change over time and space. By plotting her data on a map and combining it with historical data, she can detect diffusion patterns, divides, or clusters. Sometimes, she even discovers something she did not expect.
A new generation of desktop GIS for the Swiss Parks
This summer, the Competence Centre for Geoinformation (CCG) of the Swiss Parks Network, in collaboration with the Department of Geography of the University of Zurich (GIUZ), organised an introductory training course on ArcGIS Pro for employees of the Swiss parks.

Was uns Ortsnamen verraten
Wie sind Ortsnamen mit «Wiese» und mit «Matte» über die Schweiz verteilt? Wie lässt sich diese räumliche Verteilung erklären? Im Mastermodul «Einführung in die Onomastik» haben sich Germanistikstudierende unter anderem mit solchen Fragen befasst. Die Kartierung hat ihnen geholfen, Muster zu entdecken und Antworten zu finden.
Cholera 1855 in Basel: Between History, Epidemiology and Geographic Visualisation
In 1854, Dr. John Snow creates a map of cholera cases in London’s Soho district. He can thus show that the disease is transmitted through contaminated water. In her Master’s thesis, Inga Birkhölzer investigated what can be extracted today from the cholera figures of 1855 in Basel using geographical visualisation.

From background maps and time series to toilet tiles in the national map look
The GeoVITe platform provides topographic raster and vector maps, digital elevation models and orthophotos for research. Roman Walt, who supports and advises the users of the platform, explains in an interview how the data from GeoVITe can be used, what the added value is compared to the data from Swisstopo – and he reveals the funniest request.

Seven reasons to try ArcGIS Online
ArcGIS Online is the little brother of ArcGIS Pro, a GIS software developed and maintained by ESRI. We collected seven reasons for you to try out the light version.
QGIS Cloud: Share your maps and geodata
UZH’s QGIS Cloud is ready! In this cloud, students and researchers can publish maps and geodata, share them with others – or get inspired by others. Leyla Ciragan from the GIS Hub explains what the QGIS Cloud is and what you need to know as a user.
GIS Hub officially launched!
On Friday, the 11th of November, we officially launched the GIS Hub together with the participants of the workshop, members of the Advisory Board and the entire GIS Hub Team.
Auf der Suche nach Mehrdimensionalität in Raum und Zeit
Eine Nation, eine Sprache – nach diesem Grundsatz wurde die Ausbreitung von Sprachen früher oft kartiert. «Doch Sprachen sind nicht nur territorial», sagt Johannes Kabatek, ordentlicher Professor für romanische Philologie an der Universität Zürich. Er sucht deshalb nach Möglichkeiten, wie sich Sprachen mehrschichtig im Raum und über die Zeit darstellen lassen.

Was die Karte dem Linguisten enthüllt
Als Niederlandist untersucht Chris De Wulf zum Beispiel, wie sich Diminutivendungen* in verschiedenen Dialekten über die Zeit verändern. Die Endungen extrahiert er aus Dokumenten wie Tagebüchern oder Urkunden – automatisch versteht sich – und speichert sie in Tabellen. Doch erst durchs Kartieren enthüllen sich ihm die Zusammenhänge.
Von der Wundermaschine zum kritischen Tool
Als sich Archäologe Timo Geitlinger vor ein paar Jahren zum ersten Mal an eine GIS-Software wagt, meint er, eine Wundermaschine vor sich zu haben. Heute hingegen weiss er, wie die Wunder zustande kommen und wie vielseitig und geschickt er die Software in seiner Forschung einsetzen kann.
“I will use GIS software again in my career”
Lovasoa Rakotozafy, a PhD student in Ecology at UZH, used a GIS software to prepare her field work in Madagascar. «There are a lot of things of which I don’t know how I would have done them without the software», she admits.
