How does data accuracy influence the reliability of digital viewshed models? A case study with wind turbines
Original language description
Viewshed analysis is a GIS tool commonly used in a number of research and practical spatial analyses. Input data and their spatial uncertainty are important aspects affecting analysis reliability. Given that inappropriately selected input geodata can produce imprecise visibility models and as a result cause incorrect spatial decisions, quantifying the effect of this uncertainty on resulting visibility models is important for the models' subsequent use. The objective of our study was to evaluate the suitability of digital surface models with varying levels of detail (a LiDAR-based model and models based upon vector data at differing scales) for simple (binary) viewshed analysis of wind turbines (three wind parks each containing 3?6 turbines). Visibilitymodels based upon this input data were compared with actual visibility from 150 control points at random locations. The study results confirmed the prediction that the viewshed model based on more precise input data corresponded more clo
