Interpretation Guide: Québec Landsat Satellite Image Mosaics
This guide describes the method used to create Landsat satellite mosaics and provides interpretation keys for the optimal use of these mosaics.
User’s Guide: Products derived from LiDAR Data
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.
Ecological Mapping of the Vegetation of Northern Québec – Mapping Standard
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.
Photographic Interpretation of Forest Species in Southern Québec
The photo-interpretation of the different species that can be found over their full range of possible growing conditions proves to be of great complexity. This guide provides criteria for the identification of commercial coniferous and deciduous tree species based on characteristic shapes, textures and colors that are visible when photo-interpreting digital 3D aerial photos. The task of photo-interpreters, novices or experienced, is thus facilitated. The identification criteria provided in this guide are based on “frame by frame” 20 cm resolution digital aerial photographs.
Province-Wide LiDAR Data Acquisition – Impact Analysis and Recommendations
This report presents the results and recommendations of an analysis of the economic benefits for the gouvernement du Québec and the forest industry relating to LiDAR data acquisition. The sections present, in order, the source and nature of the information as well as the method used for the impact analysis. The results of the analysis and their interpretation follow, leading to some recommendations regarding LiDAR data acquisition.
