This user guide facilitates the identification of surficial deposits and borrow pits using LiDAR data and aerial photographs. The high accuracy of LiDAR data is particularly useful for observing geomorphological details that are difficult to see using other data sources (e.g., aerial photographs only). The shaded relief digital terrain model produced from LiDAR data removes the masking effect of vegetation, exposing the underlying terrain and thus allowing an easier and more precise identification of surficial deposits. Using this guide to identify more easily and more precisely surficial deposits can undoubtedly facilitate preliminary analyses and field work, as well as the search for material favourable to civil engineering work and the construction of roads.

This user’s guide presents how to view or modify LiDAR derived products in both ArcGIS and QGIS. Basic and advanced features are shown, for example changing a symbology, combining a hillshade and transparent DTM, creating a new hillshade or slope model, assembling or clipping rasters, creating contour lines, reclassifying a raster, converting a raster to vector format and creating a focal CHM or a topographic wetness index.

The vegetation map of northern Québec provides information on forest and non-forest ecosystems for the entire territory located north of the 53rd parallel (680 000 km²). This map is based on the application of rigorous criteria for stratifying the vegetation and the physical environment. To facilitate the use and understanding of the map, this document presents the land cover stratification criteria as well as the different classes of vegetation and surficial deposits used.
