Random Forest Classification of three different species of trees in Delft, based on AHN point clouds: Additional Thesis

Trees are an important aspect of the world around us, and play a sufficient role in our daily lives. They contribute to human health and well-being in various ways. Tree inventory and monitoring are of great interest for biomass estimations and changes in the purifying effect on the air. It is a very time consuming and cost inefficient way to...

Automated photogrammetry of outcrops: with MicMac

Every year the second years of the bachelor Applied Earth Science have a geological fieldwork in Southern France. To supervise the students after a day in the field the idea is to collect a 3D model database of the outcrops in the field. This is done by photogrammetry and the open-source program MicMac.<br/>In this report an acquisition protocol...

The effectiveness of a snow fence in the dry Andes region of Chile

The region of Coquimbo, Chile, is located adjacent to the dry Andes. Water is scarce, and with very little precipitation during spring and summer, water supply in these seasons depends mostly on melt water from snow in the Andes mountains. <br/>A project funded by the local government was conducted by CEAZA, a research institute based in the...

Usage of drones in the event of an incident on the rail: Measuring efficient and accurate

From this study can be concluded that using drones equipped with cameras a 3D model van be created of an incident on the rail. From the recordings, a 3D model van be made using photogrammetry. In this model it is possible to measure post distances with an estimated error of less than 1 centimeter. The distances between the laser scanner point...
