LIDAR-BASED SPATIAL MODELLING OF SOIL MOISTURE CONDITIONS AND OTHER PROPERTIES ALONG A BOREAL WETLAND-UPLAND CATENA
This poster provides an overview of how DEM-derived wet-area and cartographic depth-to-water maps can be used to map soil type, vegetation type and drainage conditions across the landscape. Also addressed is the topic of wetland delineation, by comparing GPS-tracked wetland areas with areas indicated to be wet by way of the cartographic depth-to-water index (DTW) and the topographic wetness index (TWI, or SWI meanign soil wetness index), with both derived from high-(LiDAR) and low-resolution DEMs.
EXAMINING AND FURTHER DEVELOPING PREDICTIVE SOIL MOISTURE MODELS BASED ON HIGH RESOLUTION DEM DATASETS
This poster informs about the general process of generating LiDAR-based DEMs, and some of the issues encountered when turning these DEMs into reliable flow channel, wet areas and cartographic depth-to-water maps. Allowing the numerical flow accumulation process to continue automatically across roads on account of culvert placements and other structures underneath the road surface is one of these issues.
