As I realized that I have a really huge family I was keen to digitize the current family tree and get into contact to my relatives. For getting things done, I choose the open source genealogy software Gramps to record all offline information about my family members and create a database as base for further investigations, updates and of course spatial visualization. After that, I exported a database view and visualized it with QGIS.
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…
While preparing for an upcoming presentation at the annual meeting of the American Geophysical Union (AGU) I came across a topic that I thought might make an interesting blog post. The presentation is about using data from the Sentinel-1 mission for Earth Science applications. The Sentinel-1 spacecraft are C-band SAR systems launched and operated by the European Space Agency (ESA). An innovative aspect of this mission is that the collection scenario devised by ESA is systematic and very broad in coverage. Using Sentinel-1 we can monitor Earth using SAR data like never before.
Sentinel-2 is the optical satellite of the Copernicus programme. It can be compared to Landsat, although it has a better resolution, of 10 to 20 meters. We’ll be using it for crop monitoring with simple vegetation indices.
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.
Today I received the newsletter from Mapbox with interesting screenshots of their new mapstyles. The company convinced many users with nice basemap styles already in the past. Now they updated their background mapstyles for webmap usage. Just have a look: All pictures are from Mapbox. In my opinion the new styles fits good for modern map applications. If you’re interested in other background maps, check out this article – Map Compare. If you’re interested in getting more information about Mapbox styles, just visit this Mapbox article.
I was reading an article entitled “China, the megalopolis of 110 million inhabitants that impresses the world” on a popular online journal (see article) and after a dozen lines read: “Beijing is already surrounded by six ring roads, [… ] but the seventh will be 940 kilometers long.” How many are 940 km for example along a circle, as the Circular Highway of Milan?
