Errata : Old Carbon 

 Dear Email Subscribers,A correction to my last post on ancient human footprints from New Mexico. I mistakenly typed their estimated age as 22,0000 (Two hundred and twenty thousand). The correct assigned age in the paper I referred to is 22,000 (Twenty two

Short Announcement: Your Input is Needed… A Readers Survey 

We are always looking for new ideas, tutorials, work flows, solutions. Unfortunately we were not able to write so much in the past for our beloved blog Digital-Geography.com. Therefore I am asking you today: What do you want to know, read, see, be advised on in the future? Take this short survey as a starting point so we can gather your ideas and write about the stuff you would like to read in the future. Our Small Survey Looking ahead we would like to start with some new motivation into 2018. [...]

Ten years of Mountain Beltway 

Callan has been blogging about geology for a decade. Here are a few reflections on those ten years behind the wheel of "Mountain

Year in review 

We approach the end of another calendar year, and with it comes my ninth anniversary of beginning to write about geology online. (A year from now will mark a decade of geoblogging for me!) It’s been a rough year, health-wise for my friends and family. Loved ones have suffered strokes, brain cancer, Alzheimer’s, and other horrible ailments. I myself have been battling a persistent respiratory infection for most of the

Letters, op-eds, and blogs express concern over defunding of geological survey 

Geologists and geology advocates are making their opinions known about Arizona Gov. Doug Ducey's government consolidation decision to defund the Arizona Geological Survey as of June 30.  The AZGS duties have been handed over to the University of Arizona, which is providing partial funding for one year while the Survey is expected to become fully self supporting from grants and fees

Science bloggers – join the 2016 General Assembly blogroll! 

Will you be blogging at the 2016 General Assembly? If so, sign up here and we’ll add you to our official blogroll. We will be compiling a list of blogs that feature posts about the EGU General Assembly and making it available on GeoLog, the official blog of the European Geosciences Union. We’d ask you to write posts that relate directly to the Assembly during the conference in Vienna (17 – 22 April). The content of each blog on this list is the responsibility of the authors and is not [...]

Job Page – reloaded 

Since 3 years digital-geography.com provides a nice page for your job search in the fields of GIS and Geosciences. As most of our visitors are young professionals, which are not necessarily interested in a job near their home, we started this job page with a webmap from the very beginning. Now we made a big rework of the side. The Early Beginning Just have a look at this old side: The old pages where based on a single map for each week and was implemented using openlayers. This was every time [...]

The benefits of an informed prior 

Since Bayesian priors seem to have come up on a couple of blogs recently... A few weeks ago I got a rather spammy email about a “climate change challenge” from someone I'd not come across before. Looking at his “publication list”, that is perhaps not so surprising (the most recent ACP submission listed there was rejected without review, so cannot be found on their web site). Anyway, it's

Hitting a nerve with popular posts 

I blog here a few times a week, when I can manage it. Mostly I focus on new things I discover on field trips, advances in geologic imagery, and structural geology.  I get about 500 readers per day. But occasionally I write about other things, like creationism or current events disasters like earthquakes, and those posts garner a lot more attention. They get shared and reshared and spread out. My

5 reasons why I blog 

5 reasons why I blog, and why shall you. About 4 years ago I started blogging and building a website/blog with content about GIS, geodata and programming. As I am an IT consultant for banks and mainly working as a testmanager in a SAP-software surrounding in Switzerland you might ask: “Why the heck do you this?”. Check out my motivation and reasons why I blog and spend time here. I studied Geography and Mathematics at the Freie University Berlin with the aim to become a teacher one [...]

Geospatial World: geospatial industry magazine for free 

The geospatial media industry is really negligible. Some blogs here, some magazines there. Luckily their authors are very hard-working. This article will introduce a magazine called “Geospatial World” (formerly known as GIS Development magazine). Since 1997 the magazine investigates geo-related topics and writes about present viewpoints of experts, worldnews, case studies, reviews, upcoming technologies and more. Besides the monthly free downloadable and printable PDF-magazine, [...]

What is better: a map or a picture? 

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? I immediately had the need to go and draw a circle with a circumference of 940 km, because I realized [...]

AP Changes Policy On Labeling Climate “Skeptics” 

A lot of us who write blogs about science face the issue of how to label those who think climate change isn’t real, or who think the science is all wrong. Just to be clear, virtually none of these folks have any background in atmospheric science, as several studies have clearly shown, but that still leaves the issue to be dealt with. I can tell you from my own experience

Geo Business and Social Media: Blogs, Twitter and Facebook 

This year I visited the Intergeo 2015 not without reason. I was invited at the booth of the German GeoBusiness Commission for an interview. The interplay of geobusiness and social media should be examined more closely. I like to publish my theses here as well<! – More -> Talk about your deeds The German (geo-)economic landscape is rich in smart companies, ideas, concepts and great products. Nevertheless, Germany is “dubbed” as a country of the small and medium-sized [...]

Spot the difference 

This Greek thing seems to be all the rage on some blogs I could mention, but I struggle to get excited by it. According to the Grauniad website today, The IMF views a debt-to-GDP ratio above 120% as unsustainable. Here, for some context, are some recent data for a couple of countries: I won't be offering prizes for guessing the identities of Countries A and B. One of them has

Vagabonding on Dangerous Ground: On the Road in the Pacific Northwest (a new blog series) 

The Lost Coast of Northern California If you've been following my blogs for the last few weeks, then you know I've been on the road in the Pacific Northwest. I'm not quite home yet, but I'm headed that way soon, and I've realized that there has been a convergence of events that are leading to my next blog series. I've decided to call it "Vagabonding on Dangerous Ground". The Devil's

Carnival of Space #403 

Back in the days before Tumblr and facebook and twitter, people wrote blogs, read other blogs, and collate series of posts about common themes into link compilations called "Carnivals."  These days, most carnivals have dies out, due to the death of independent blogging, the loss of attention span to microsocial, and the increasing automation of trend formation.  But a few still live on, and

Mine Reclamation & Closure Costs 

    Our training as engineers a long time ago in South Africa included no courses on cost estimation.  For that was the province of Quantity Surveyors–a speciality and a degree in itself.  It was considered unprofessional for engineers, or anybody else, to compile a cost estimate.  Only professional quantity surveyors were entitled to do

Blogs and social media at the Assembly – tune in to the conference action 

With hundreds of oral presentations, PICO sessions and poster presentations taking place each day, it can be difficult to keep abreast of everything that is on offer during the General Assembly. As well as finding highlights of interesting conference papers, lectures and workshops in the daily newsletter at the General Assembly, EGU Today, you can also keep up to date with all the conference activities online. Blogging GeoLog will be updated regularly throughout the General Assembly, [...]

Mining Reflections on Opera and Books Read 

A typical Vancouver Saturday:  cool, overcast, some sunny periods, and much reading.   Then after six pm a bottle of wine and an opera. Here are some of the books I dipped into today–I have been reading some for a while; some are old and should have been finished a long time ago; and some are
