Introducing: My personal application list

Once again I switched from Windows back to Ubuntu as I only needed Win for my granted ESRI license but hated to be “interrupted” by automatic updates, missing dll libraries and crashing flash container plugins on Firefox. So now I am building my personal computational slave once again based on Ubuntu and wanted to share with you my list of applications that I need for my daily work with geodata, matrices, graphics, cartographic outputs and statistical analysis.

Geotagging Basics with ExifTool

  Why Geotagging? In a recent post, I discussed the new drone that I got for the holidays and a bit about how I was using it for developing map products.  I do this using structure from motion algorithms and when working with a lot of images it is a great help if there is a good initial estimate of the image location.  This is where geotagging comes in. If you have a smartphone, then you are familiar with geotagging.  Most iPhone and Android devices tag their images when they are collected.  That is great if you are uploading to Facebook or Pinterest,…

Maptime Berlin: what was/what will be

In the middle of September the first Maptime Berlin took place. I was totally amazed to see so many people sitting there, being interested in mapping, opensource, cartography and software. At least 40 people from different places of the world with different background (sociology, coding, styling, etc.) met at the Supermarkt Berlin (an open place to work together) to share their knowledge and learn new stuff. Here just a few photos: What was done at MaptimeBER After a short introduction from everyone Alsino presented what is Maptime all about: bringing people together, share the joy of creating and consuming maps…

Overview: Newest developments from ESRI

At this years 11th geoforum of central Germany ESRI showed some new developments in their ArcGIS online portfolio. Those were published 23rd of September. Let me please introduce you to some of these features. If you came across the website of ESRI you might have mentioned that current ArcGIS offline or desktop applications are beyond the functional possibilities of the new ArcGIS online framework. One of these was the new multi-directional shadow algorithm which came on stage on the ArcGIS online platform and is now a downloadable function. Of course they will be available with the upcoming ArcGIS pro but…

Opticks – My first step with the OpenSource ERDAS pendant

David vs. Goliath? Since years I work with QGis, now I will test the OpenSource ERDAS pendant Opticks for remote sensing issues with raster data. It would be very nice, if I could ban all evil proprietary GIS-software from my dektop for ever. The specs of Opticks sounds very good – lot of data types are supported, Opticks can handle big data load (>16 GB per image) etc. After that I had to install the glorious piece of software to my Linux-OS (it’s also available for Windows and Solaris as well). Let’s get a first impression of Opticks You can…

FastGAPP – Fast Geochemical Analysis Plotting Program

Geochemical studies of igneous rocks are fundamental to classify rock types in terms of main-, minor-, trace element whole-rock chemistry. Together with petrographic observations from thin sections it is possible to classify igneous rocks and to draw interpretations about: The petrogenesis and evolution of igneous rocks. The thermal and barometric conditions in which a primary magma have formed. The magmatic processes that might be involved in the evolution of igneous rocks. The geotectonic environment in which igneous rocks might have formed. Specific programs for the evaluation of geochemical data of igneous rocks are rare and often very difficult to use.…
