Sažetak
Quantification and monitoring of complex geomorphic spatio-temporal changes requires multiple field surveys and creation of very-high resolution (VHR) digital elevation models (DEMs). Due to pronounced terrain roughness and complex surface topography modelling of gully erosion induced spatio- temporal changes can be very challenging. Although advanced geospatial technologies, such as terrestrial laser scanning (TLS), provide good basis for modeling of complex morphological features, certain limitations still exist that can lead to the overall devaluation in model quality. Most of these limitations are related to the non-systematic TLS survey approach, that lacks thorough survey planning and preparation phases. Main aim of our research was to provide guidelines for optimization of TLS surveys over gully erosion affected areas, through development of new systematic survey methodology. Established systematic TLS survey methodology allows multiple detection, quantification and monitoring of spatio-temporal changes, where survey characteristics are adjusted to the local terrain characteristics and specifications of available terrestrial laser scanner. Developed survey methodology was applied for TLS survey over chosen gully site at Pag Island, Croatia.
