  • To clarify the estimation error of snow depth spatial distribution with different DEM mesh sizes, airborne laser scanning during two periods (ground surface exposure and snow peak) and a snow depth survey were conducted in the Jozankei Dam catchment area ,in the Hokkaido, region of northern Japan. The results of these two investigations were compared for adequate evaluation of the method to determine the spatial distribution of snow depth. Our regression analysis for different topographic parameters of snow depth showed that the 50-m mesh provided a better fit, while the conformity of the 5-m mesh was poor. In addition, the snow water equivalent with the 50-m mesh demonstrated good compatibility with the results of the snow survey, while the outcome for the 5-m mesh indicated that improvements are needed.
