| Abstract | The Remote Predictive Mapping Project (RPM), recently renamed to Systematic Mapping of Arctic Canada by Remote Techniques (aka SMART) is focused on developing efficient and timely mapping of large areas
of the North that require up-dated and /or more detailed bedrock mapping. This poster demonstrates a step-by-step approach for accomplishing this task using an example from the Hall Peninsula in central Baffin Island. This area was last mapped in the
1950's and both bedrock and surficial geology requires updating. We are accomplishing this task by applying both visual and computer-assisted processing techniques to various geoscience data including remotely sensed (LANDSAT and SPOT), geophysical
(magnetics) and topographic (DEM) data to extract both lithological and structural information. We incorporate legacy geological data (existing maps, field observations) to assist in geologically calibrating the predictive maps we produce.
The
remote predictive mapping process begins with the acquisition, processing, and geological interpretation of available remotely sensed data sets, and results in predictive maps that outline interpreted units and structures in the study area. RPM can
be either completed in isolation from field-based mapping or can be intimately integrated with it in order to ground truth the interpretation as field mapping proceeds. Figure 1 shows a summary of the RPM process integrated into the work flow of a
geological mapping project. Regardless of whether the interpretation of remotely sensed data is fully integrated into a geological mapping project or not, the following provides a systematic outline of RPM work flow. |
