LiDAR Services International (LSI), une entreprise dont le siège social est situé à Calgary, a effectué un levé LiDAR aérien pour la réserve de la biosphère du Lac-Redberry (RBLR) et pour Agriculture et Agroalimentaire Canada (AAC) en octobre 2011. Le projet comprenait la collecte de données LiDAR pour un bloc d'une superficie de 362,97 km2, soit 252,77 km2 pour la réserve de la biosphère du lac-Redberry et 110,20 km2 pour AAC dans une zone au nord-ouest de Saskatoon (Sask.).Pour plus d'information, consulter : http://ouvert.canada.ca/data/fr/dataset/c12645b7-4f70-4c37-808d-0b1ff3bd0051

La cartographie des risques d'inondation des infrastructures d'AAC en Saskatchewan - 50 centimètres comporte des courbes de niveau à intervalles de 0,5 m, déterminées au moyen du LiDAR dans la zone d'acquisition de données de la Saskatchewan. Les courbes de niveau ont été modélisées en fonction de la classe de sol suivant une distance verticale maximale de 0,5 m et une distance horizontale de 20 m. Aucune ligne de rupture n'a été utilisée autour des entités hydrographiques, de sorte que le niveau des plans d'eau n'est pas nécessairement uniforme lorsque des données recueillies à des dates différentes se chevauchent. On a déterminé un intervalle de 5 m pour les courbes maîtresses, tandis que les courbes intermédiaires ont un intervalle de 0,5 m.

Background: More than 80% of the heat produced in the Earth's crust comes from granitoid rocks. When granitoid rocks form they naturally concentrate radioactive elements such as U, Th, and K, and the radiogenic decay of these elements is an exothermic reaction. The radioactive decay of these elements within a granitoid body may generate local heat anomalies and elevated geothermal gradient at relatively shallow crustal levels. In combination with other local rock properties (e.g, porosity, permeability, thermal conductivity), radiogenic heat has the potential to generate a geothermal resource. The decay of radioactive elements converts mass into radiation energy, which in turn gets converted to heat. While all naturally radioactive isotopes generate some heat, significant heat generation only occurs from the decay of 238 U ,235 U ,232 Th and 40 K. Therefore, potential heat production is governed by the concentrations of U ,Th and K in the rock. In igneous rocks, radiogenic heat production is dependent on the bulk chemistry of the rock and decreases from acidic (e.g. granite) through basic to ultra basic rock types. Therefore, granites with anomalously high concentrations of U ,Th and K are targets for calculating potential radiogenic heat production. Potential radiogenic heat production (A)from plutonic rocks can be calculated using this equation: A (\\u03BCW/m 3 )=10 -5 \\u1D29 (9.52c u +2.56c K +3.48c Th ) where "c" is the concentration of radioactive elements "U" and "Th" in ppm, and "K" in %; and "\\u1D29" is the rock density. Heat production constants of the natural radio-elements U, Th, K are 9.525x10 -5 , 2.561x10 -5 and 3.477x10 -9 W/kg, respectively. Data and Methods: Geochemical data from \~1760 samples of plutonic rocks from Yukon are used to calculate potential heat production. The calculated values for radiogenic heat production (A) are plotted over the mapped distribution of Paleozoic and younger plutonic rocks and major crustal faults are also shown for reference.
