Digital Northern Ontario Engineering Geology Terrain Study (NOEGTS) - Polygons
Coordinate system: 4269 - "NAD83"Abstract:
The NOEGTS (Northern Ontario Engineering Geology Terrain Study) data set is a digital version of the 103 original cartographic NOEGTS maps. An engineering geology terrain study is an evaluation of near-surface geological conditions for the purpose of determining the engineering significance of the terrain. In this context, terrain refers to the physical aspect and characteristics of an area or landscape under observation.
The main investigative techniques used to gather the information for such a study are air photo interpretation combined with literature searches and limited field work. A total of 370 000 km2 of northern Ontario was mapped between 1977 and 1980. With conversion to a digital format, additional geological interpretation was completed on many of the maps to improve the data set. In addition, standard legends and symbology were designed so as to provide an improved cartographic product.
Base layer information includes lakes, townships, a shaded relief image and roads. Additional information and metadata are found within a readme file provided with the product.
Supplementary data can be used and are available for download from the additional documentation section.
