ABSTRACT: Knowledge of the soil and terrain characteristics of a site is essential to any development. The sooner this data is made available to the Project engineering team, the better. This kind of data helps reduce overall costs by identifying critical soil and terrain features up front allowing the Project to progress with full knowledge of these features. Too often projects poorother words the scale of the publically available data is inappropriate for the intended use. Projects need site specific data (1:5,000 or larger) while publically available earth science data tends to be at scales ranging from 1:50,000 to 1:1,000,000. A popular misconception today is that LiDAR data can be used to provide data on the characterization of soils and terrain features. LiDAR data is simply elevation data; it can be viewed using a 3D hillshade model but for the most part, provides little or no data regarding soil and terrain characterization such as material types, depth to bedrock, drainage regime, and so on. Nevertheless, this type of information can be easily garnered from stereo aerial photography by a trained geoscientist. The paper discusses new tools that are available for creating soil and terrain data at scales of 1:5,000 and larger.
RÉSUMÉ: La connaissance des caractéristiques des sols et du terrain d'un site est indispensable à tout projet de développement. Le plus tôt ces données u Projet de progresser en toute connaissance de cause. Trop souvent, les projets se développent à partir des données est inappropriée pour l'utilisation prévue. Les projets ont besoin de données spécifiques (1:5,000 ou plus) alors que les données publiques ont tendance à être à des échelles allant de 1:50,000 à 1:1,000,000. Une fausse idée populaire utilisant un modèle d'ombrage 3D, mais pour la plupart, elles fournissent très peu ou pas de données sur la caractérisation des sols et du terrain, tels que les types de matériaux, la profondeur du substrat rocheux, le régime de drainage, etc. Ce type d'information peut être facilement recueilli par un géoscientifique à partir de photographie aérienne stéréo. Cet article présente des nouveaux outils qui sont disponibles pour créer des données de sols et de terrain à des échelles de 1 :5,000 ou plus.
