Emit #1 – Into Spatiotemporal

One of my new year’s resolutions for 2018 was to “blog more”. Not being very active on the well-known social media: a bit tired of Twitter, never really into Facebook, bit of LinkedIn.  OSGeo mailing lists, GitHub and Gitter is where you can find me most (thanks Jody, for reminding!). And…

Even 3D-versions for several of these datasets are upcoming. These and other nuggets can be found and downloaded via our national geo-portal:…

Into the Weather – Part 2 – Fun with Raspberry Pi

This is a follow-up to “Into the Weather – Part 1 – Exploring weewx”. Sorry, still almost no geospatial content for now. To recap: I am trying to setup an infrastructure where measurements from a Davis Vantage Pro2 Weather Station are collected and exposed to web services, most notably OGC Services like…
