Snow surface mapping and change detection in avalanche release areas using a consumer-grade UAS and SfM photogrammetry

One of the main limitations of the present study for the operational application of UAS-SfM in forest inventories was the inefficiency of the UAS-SfM data acquisition in

The accuracy of the ensemble model was slightly better than all individual models for generating the snow avalanche hazard map, as validation analyses showed an AUROC = 0.966 and

This study examines the validity, feasibility and accept- ability of using a consumer grade activity device (ConD) as a substitute for a commonly used research grade acti-

1) The topography and climate of the study area allows for snow avalanches, and, generally speaking, most of the railway lies within potential snow avalanche run-out areas. Within the

This could be very useful for future missions since change detection can be done more effectively in an interesting area by using time series of geocoded images with different

In order to address the need for scalability, increased automation and to minimize operator training costs, we propose a custom ground control station (GCS) providing functions

Analyses of 16S rRNA gene copy yields found that bacterial numbers decreased with increasing humidity, peaked during spring for air sam- ples (Additional file 1: Table S4; Figure
