JuxtaposeJS and the Death (and Re-Birth) of Bogoslof Island

This post is just a quick update on a unique event unfolding in my home state of Alaska and a cool new tool to help you post image sliders on the web.  First, let’s start with the event. The Eruption of Bogoslof Island Over the past few weeks, a volcano has been erupting in Alaska.  This by itself is not that unique, as we have lots of volcanoes and they tend to erupt pretty frequently.  You can check out the current activity for yourself at the Alaska Volcano Observatory.  This most recent eruption is a bit different though.  The island is…

Intergeo 2016 Day One: drones and drones and drones

The first day of the Intergeo 2016 and it was just mind blowing. The last years we saw a small increase in drone technology companies but especially here in Hamburg they seem to be everywhere. So there is the business rolling. About 500 exhibitors are here showing their latest products and services. At least 130 of them are into drone technology. The hottest shit is most likely the drone based laser scanning systems. So drones are getting more powerful, we see more and more fixed wing systems and the 3D laser scanners are getting smaller and smaller every year. I…

AHP for ArcGIS 10.x using Python

When it comes to site selection problems or suitability models, the spatial Multi-Criteria Analysis (Weighted Overlay) is the most commonly used method. It’s easy, simple and popular. However, if it’s your first time to come across this method, it’s highly recommended to have a look at this link. After defining the problem you want to solve, the next 4-steps are followed to perform this method. Determine significant layers. Reclassify the layers. Weight the input layers. Sum up the weighted layers My concern was always about how I can assign a weight to each layer in a kind of scientific way.…

Maps of “Out of Eden Walk” by Paul Salopek (National Geographic)

Today I had the chance to attend a lecture by Paul Salopek in Tbilisi, Georgia. This lecture took me to the idea to write a short review about Paul Salopek and his project here on Digital-Geography because he mentioned several times that mapping his journey is one of his main goals. Some would wonder now: Which journey? – I’ll tell you what’s about: Paul Salopek is a journalist of National Geographic who is doing an amazing project at the moment. He is walking from the birthplace of humanity in Ethiopia at the pathways of human spreading around our globe for more…
