screenshot-from-2014-12-16-174447QGIS 2.6 landed recently on this planet and it already brought great improvements to our daily work with geodata, the way we publish our results and the convenience in our workflows. But due to the very ambitious release plan of the QGIS core team and the great work of Klas we can have a look at the upcoming features in QGIS 2.8 major version already. Check em out:

Short Announcement: new MOOC on GeoInt!

2014-12-18 20_37_43-CourseraToday I received an interesting E-mail from Pennstate University which pointed towards an upcoming MOOC with a more or less special focus: Geospatial Intelligence. The title is Geospatial Intelligence & the Geospatial Revolution: Learn how the revolution in geospatial technology combined with the tradecraft of Geospatial Intelligence (GEOINT) have changed how we develop insights about how humans use geography, and discover the power of GEOINT. So let’s have a look at.

I’ve been experimenting with very short QGIS tips on YouTube, and if you like them I’ll continue to create them. They may or may not reveal something extraordinary, and if you have an idea of something worth creating a short video on, leave a comment or send me an e-mail, tweet, or whatever.

International Year of Soils 2015 – Summarize of Soil content

topelement

Here comes another more or less off-topic post on soil science because I realized that the feedback for the last two soil related contents about global soil data and soil atlas was quite surprising. So it seems like that there are some soil scientists or at least digital geographers with an interest in soil science among us. This post is related to the upcoming YEAR OF SOIL 2015 which was oficially initiated on December 5th, the World Soil Day. In Germany, the upcoming german Soiltype of the year 2015 will be “Pseudogley” after celebrating the so called “Weinbergboden” in 2014.  …

A small tool with Python: the shapefile archiver

the dialogLet me introduce to you, guys, my first Python tool: “Shapefile Archiver”. Usually, I face lots of problems in managing my shapefiles. My first problem is backing them up in a decent way, especially, before starting some experimental things on them (That sounds scary!), while the second problem is that Finder/Windows explorer doesn’t tell me about the shapefile more than its name!. Moreover, Finder/Windows explorer shows the shapefile as a bunch of files (*.shp, *.prj, *.shx, *.dbf,…) which makes me feel annoyed especially because I’m too lazy to open QGIS browser or ArcCataloge every time I want to explore my…

Create custom markers with R for your webmap

piechart markerWhen it comes to webmapping there are thousands of possible markers you can choose from but when it comes to markers depending on the data, which is inside the shapefile, possibilities are more limited. In leaflet you can define different icons according to the attributes of your data by defining the icon url in an attribute. Let me show you, how to use the data in each feature to create a custom icon like a piechart marker using R.

Since QGIS 2.6 was released with a lot of new features and functions I’ve been testing it sporadic and have come to realise that the quality and functionality of symbol styling and labelling is so high that ESRI ArcMap no longer can match it. Honestly I haven’t tested the 10.3 version of ArcMap, so my experience is based on previous versions. Here I’ll use an example to highlight some of the extensive possibilities offered in QGIS.
