Unmanned aerial vehicle (UAV)-based snow depth is mapped as the difference between snow-on and snow-off digital surface models (DSMs), which are derived using the structure from motion (SfM) technique with ground control points (GCPs).

Intercomparison of photogrammetric platforms for spatially continuous snow depth mapping [PDF]
Snow depth has traditionally been estimated based on point measurements collected either manually or at automated weather stations. Point measurements, though, do not represent the high spatial variability in snow depths present in alpine terrain ...

EVALUATING THE CONSISTENCY OF REMOTE SENSING BASED SNOW DEPTH PRODUCTS IN ARID ZONE OF WESTERN CHINA [PDF]
Snow cover is a sensitive indicator of global climate change. Among various snow cover parameters, snow depth which can indicate snow accumulation is essential for retrieving snow water equivalent.

An Approaching on Estimating of Snow Depth and Snow Water Equivalent.
Snow water equivalent (SWE) and snow depth (SD) is estimating using Snow 17 model for several meteorological mountain stations from Romania. The model uses air temperature as the sole index to determine the energy exchange across the snow-air interface.

Persistence in intra‐annual snow depth distribution: 2. Fractal analysis of snow depth development [PDF]
We present an analysis of high resolution laser scanning data of snow depths of three different slopes in the Wannengrat catchment (introduced in part 1) using omnidirectional and directional variograms for three specific terrain features; cross‐loaded slopes, lee slopes, and windward slopes.
