Description: This layer is the result of nearly 50 years of bedrock mapping and it continues to change as new interpretations are made and more data is collected through field work and analysis. This layer is meant to be used in conjunction with the Bedrock Geology Relatetable and the Bedrock Geology Lines layer.Using digital data that existed in files that generally followed National Topographic System (NTS) grids at the 1:20,000 and 1:50,000 scale. These files were combined and edited (e.g., edge matching at file boundaries) to create the provincial, continuous coverage layer. New point data (2018 - present) are collected digitally using GPS enabled tablets. Updates to the polygon features are digitized in ArcGIS. Mapping is generally conducted at the 1:20,000 scale.This layer is updated periodically when new information resulting from additional geologic mapping impacts polygon boundaries or associated attributes. This is most likely to occur annually after field projects are completed. Refinements and minor changes are ongoing and may occur on a more frequent basis.A separate table, BedrockGeology_Relate, with additional information about each unit in the feature class is available. This table can be used as a relate or join within your GIS.See attached Excel file, NBGeology Geodatabase Structure.xlsx
