Spotlights

The spotlights will focus on conceptual as well as technical topics related to the general task of reaching out for the project goals.

Automated setup of working environment

Setting up a working or project environment requires the definition of different folder paths and the loading of necessary R packages and additional functions. If, in addition, external APIs (application programming interface) of QGIS, SAGA, GRASS Orfeo Toolbox (to name the most important) are to be integrated stably and without great effort, the associated paths and environment variables must also be defined correctly.

Deriving a CHM from LiDAR & more

Light detection and ranging (LiDAR) observations are point clouds representing the returns of laser pulses reflected from objects, e.g. a tree canopy. Processing LiDAR (or optical point cloud) data generally requires more computational resources than 2D optical observations. The spotlit provides both technical handling of LiDAR data as well as some helpful hints how to optimize the technical and conceptual workflow of programming, data handling and information gathering.

Best Practice Scripts & Functions in R

Opinions differ widely on how best to organize the programming workflow in general and the development of scripts and functions in particular. The probably supreme rule is to remain consistent in the naming of functions, variables, etc.. You will see in the example scripts that this is not as easy as it looks like…

Segmentation Strategies

In nature conservation, forestry and landscape management, quantifiable knowledge is available over a wide area and is closely linked to remote sensing. Especially the LiDAR data are of inheritable importance as they offer the possibility to recognize microstructures and to distinguish tree individuals from each other. If a delimitation is successful, tree positions, tree heights, growth rates and horizontal and vertical distribution patterns can be calculated.

Validation Strategies

How to operationalize Paradigms?

Actually if we take an straightforward example for using GIS software, a very nice and apparently simple one is the idea that one is able to calculate a representation of the worlds surface. This means more ore less a to get an idea of the altitude of a lot of points.
