Service Areas, Traffic and QGIS

Our author Riccardo recently published an article on GeoNet where he described the traffic aware analysis of service areas (isochrones) in ArcGIS Pro with the analytical support of ArcGIS Online. I searched for a way to do something similar in QGIS. So let’s follow the white rabbit.

Mapalomalia: First web geological modeling platform

Mapalomalia lets geologists create and visualize 3D geological models from their browsers. It’s a free to use geological modeling platform. I hope people will use it to convey information about our planet that helps humankind to tackle big problems and at the same times makes geological modeling easier. I have developed it with input from many geologists, and by releasing it early I hope to receive more input from many more geologists. Just sign up here to start creating models.

The Geography of Tweets: Reading Tweets with QGIS

Anita showed some nice examples of tweets in QGIS in 2012. Since then it seemed to be quiet about the twitter-content in QGIS. Yet tweets can be an interesting source of information. Sometimes they can tell you something about the spatiotemporal dimensions regarding a keyword, the digital heartbeat of a defined region and many more. Yet we need to be careful with the data as it is completely biased. But how to get this data stream into QGIS?
