HERE maps Berlin-Munich by cat

Navigating from a to b is really easy today. Once you have a power connector in your car (bike, bicycle, scooter or whatever) and a mounting point, smartphones are absolutely comparable with common navigation units for vehicles. App sharing onto new car infotainment systems makes it easy to choose your preferred navigation software also in current car models, if you’re not satisfied with the build in software. Also on your desktop many applications will guide you to your preferred destination. It’s time to check out the current navigation solutions on the market.

How a QGIS plugin saved my day: autotrace

3483780One of my favourite horror exercises for students was the digitization of geological maps. Everyone hated it as you need to take of snapping options, correct attributes, and always needed to check with the background map which was most of the times a bad quality scan of an old never-heard-of-this-country geological map.

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

Winter_GIMMS

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.
