Visualizing spatial data is an important task. In this mini-tutorial, you will learn how to quickly visualize OpenStreetMap (OSM) data with PostGIS and QGIS. The idea is to get you started as fast as possible, and to make the most out of your data. Installing QGIS QGIS is freely available as Open Source software and […]

In times of COVID-19, governments contemplate tough measures to identify and trace infected people. These measures include the utilization of mobile phone data to trace down infected individuals and subsequently contacts to curb the epidemic. This article shows how PostGIS’ functions can be used to identify “overlapping” sections of infected and healthy individuals by analysing tracks […]

Last time we imported OpenStreetMap datasets from Iceland to PostGIS. To quickly visualize our OSM data results, we will now use QGIS to render our datasets and generate some nice maps on the client. Let’s start with our prerequisites: A PostGIS enabled PostgreSQL database preloaded with OpenStreetMap datasets as described in blogpost https://www.cybertec-postgresql.com/en/open-street-map-to-postgis-the-basics/ An up […]

OSM to PostGIS – The Basics Ever wondered how to import OSM (OpenStreetMap) data into PostGIS [1] for the purpose of visualization and further analytics? Here are the basic steps to do so. There are a bunch of tools on the market— osm2pgsql; imposm; ogr2org; just to mention some of those. In this article I […]
