Predictive surficial geology, Washburn Lake area, Victoria Island, Nunavut, NTS 77-E and 77-F east / [Authors: D.R. Sharpe ... [et al.]]. : M183-1/172-2014E-PDF
"The predictive surficial geology map combines remotely predicted map and visually interpreted imagery from LANDSAT and SPOT data. Machine-automated classification was integrated with landform and regional ground-truth data. The tonal character of spectral data, moisture content, controlled by sediment texture, topographic position, vegetation, and material thickness is mapped by machine methods. Visual analysis of terrain form, with expert knowledge, reveals a series of crosscut streamlined flow fields that record a complex glacial history, including glaciolacustrine and marine limit water plains. Scoured bedrock in an east-west flow field indicates that it is an erosional terrain that bifurcates a high area of thick, ice-cored, hummocky terrain. Remotely predicted map methods are efficient, accurate, and save time in mapping spectral details on the ground surface, allowing the geologist more time in developing the essential geological models of glaciated terrain. This publication includes the predictive surficial geology data in two formats: Sheet 1, raster (about 75%)/vector (about 25%), and Sheet 2, vector"--Abstract.
