Geoparsing: from place names in text to a map
In this brief blog post, we’ll explain what geoparsing is and how you can use the Python library developed by a former geography student at UZH.
DIY: Linking R with Web Mapping
If you missed yesterday’s workshop with Stefan from ESRI about the R-ArcGIS Bridge, we are happy to share the workshop material with you. You can read the theory part and do the exercises independently.
“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.
