So what else do we have to offer? Vision EGEA brings together young geographers in an atmosphere of respect, inclusion and personal development.

5 reasons why I blog

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.

Geospatial World: geospatial industry magazine for free

Bildschirmfoto 2015-10-27 um 08.00.23

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.

The QGIS survey needs input!

QGIS User survey

The free and open source gis QGIS started an user survey on its online webpage. The project needs your input to get the best necessary community information for prioritising future adjustments and developments.

Adding projection data to ENVI headers (GIMMS 3g example)


Once in a while you may need to take an unprojected file and add coordinate parameters to the header. Assuming you use ENVI, the hard way is to perform a reprojection via Image to Map registration in ENVI Classic. The easy way is to add the coordinate information to the header file. Here we assume you do not need to warp the file to an ellipsoid or datum. Here we use the example of GIMMS 3g data from the University of Maryland and NASA. Start by importing the data as a Binary file.   It is important to realize that…

Short Announcement: SRTM 1 Data Worldwide

coverage SRTM 1The digital elevation dataset resulting from the SRT Mission in the year 2000 is probably the most widely used digital elevation dataset in the world. It was first released with a 90 at ground resolution in a more or less global level (56° S to 60° N). In 2014 the White House announced the release of the 30 m original solution dataset. So they released parts of the dataset one-by-one. Our author Christoph just mentioned an update via Twitter.

What is better: a map or a picture?

Interchange between the 3rd Ring Road and Airport Expressway.

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?

Show your Photos in QGIS and ArcGIS: a small example

images as mouse over in QGISHi guys. Once again I found an interesting question in our Geoscientists group on facebook. One user wanted to show her photos in QGIS as she is it used from Google Maps: See a point, click on it and see the great image you’ve taken on your journey. Unfortunately the most obvious plugins failed to do it in QGIS. So check out our “at least” two usage scenarios for QGIS and ArcGIS where we will handle geotagged photos…
