When dealing with point clouds, you’ll probably run into the LAS format at some point, as it is the file format most commonly used for point clouds acquired through laser scanning. LAS supports a number of […]

Windows batch scripts are incredibly useful for processing data. You can automate many tasks by a simple batch file. The most common thing that I use is a for loop over all files of a certain […]
A colleague asked my whether it would be possible to view the current location of a user in a Leaflet-based GIS viewer. Luckily, this is very easy to do, as explained in this tutorial. All you […]
When designing a surveying network, it is important to know the accuracy of your observations in order to get a realistic estimate of the accuracy that can be achieved for the coordinates. For traditional observations such […]
Since the beginning of Covid-19, I’ve from time to time downloaded the official Dutch Covid-19 statistics (available here) and created my own plots, using a Jupyter Python notebook that you can find over on Github. But […]
During my studies in geodesy and surveying, we did a lot of linear algebra computations, as adjustment theory requires matrix computations. Naturally, Matlab was used a lot – although I preferred to stick with C++ most […]
Most laser scanners produce point clouds with irregular spacing – surfaces close to the laser scanner are scanned in much more detail than surfaces that are further away. This leads to huge point counts and file […]
For my job I deal with point clouds almost daily – in fact, much of my programming revolves around point clouds and how to extract information from them automatically. This means that it is very important […]
