Legacy 2D Seismic Lines with Ecology

The legacy seismic data (GEO_LEGACY_2D_TRIM_ECOLOGY_LN) is a value-added product derived from multiple spatial data sources enriching TRIM Miscellaneous Lines with ecology data.

The Legacy 2D Seismic with Ecology dataset (GEO_LEGACY_2D_TRIM_ECOLOGY_LN) was generated by the BC Energy Regulator to be a foundational dataset for planning, executing, and managing 2D seismic restoration projects. The seismic spatial data is derived from the BC TRIM Miscellaneous Lines dataset.

The data is value-added with physical, environmental and land use parameters to support planning operations. This includes attributes for seismic line width, alternate line use, shrub and canopy cover derived from high resolution satellite imagery. Please reference the summary report for additional information including methods and accuracy assessment.

The dataset also references attributes for soil moisture and soil nutrient regime; line elevation and orientation; adjacent cover type (species, height, and projected age); surrounding BCLSC land use information; land ownership data; forest fire; cutblocks; and wetland information sourced from the BC Geographic Warehouse. These attributes are indicative of forest cover and vegetation adjacent to the seismic line (not on-line vegetation). The dataset also indicates when the line is within identified caribou ranges.

The seismic lines are segmented to capture variable attributes along each seismic line. If for example a line is partially located on private land or a wetland, the line will be in multiple segments where the line intersects different features.

The results of this project are from a desktop analysis based on the available imagery datasets. This project is not an assessment of seismic recovery based on local ground-based field assessments. This data product should not be used in a one-to-one comparison with someone standing within a seismic line to assess ecological recovery. It is a landscape level planning tool to begin building more detailed strategies on a project-by-project level. You can find further information on the data limitations in Section 3.3 of Caslys 2D Seismic Recovery Mapping Summary Report 2023.
