The Legacy 2D Seismic with Ecology dataset <\/SPAN><\/SPAN>(GEO_LEGACY_2D_TRIM_ECOLOGY_LN) <\/SPAN>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 <\/SPAN><\/SPAN>BC TRIM Miscellaneous Lines<\/SPAN><\/SPAN><\/A> dataset. <\/SPAN><\/SPAN><\/P> 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 <\/SPAN><\/SPAN>Caslys 2D Seismic Recovery Mapping Summary Report 2023<\/SPAN><\/SPAN><\/A> for additional information including methods and accuracy assessment. <\/SPAN><\/SPAN><\/P> 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 <\/SPAN><\/SPAN>BC Geographic Warehouse<\/SPAN><\/SPAN><\/A>. 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. <\/SPAN><\/SPAN><\/P> 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. <\/SPAN><\/P> Data Dictionary<\/SPAN><\/SPAN><\/P> Attributes / Column Name<\/SPAN><\/SPAN><\/P><\/TD> Field Alias<\/SPAN><\/SPAN><\/P><\/TD> Data Type<\/SPAN><\/SPAN><\/P><\/TD> Data Precision<\/SPAN><\/SPAN><\/P><\/TD> Comments<\/SPAN><\/SPAN><\/P><\/TD><\/TR> OBJECTID<\/SPAN><\/SPAN><\/P><\/TD> Object Id<\/SPAN><\/SPAN><\/P><\/TD> Object ID<\/SPAN><\/SPAN><\/P><\/TD> Automatically assigned by database<\/SPAN><\/SPAN><\/P><\/TD><\/TR> SHAPE<\/SPAN><\/SPAN><\/P><\/TD> SHAPE<\/SPAN><\/SPAN><\/P><\/TD> Geometry (Line)<\/SPAN><\/SPAN><\/P><\/TD> Contains the geometry information for mapping software.<\/SPAN><\/SPAN><\/P><\/TD><\/TR> SHAPE.LEN<\/SPAN><\/SPAN><\/P><\/TD> SHAPE.LEN<\/SPAN><\/SPAN><\/P><\/TD> Double<\/SPAN><\/SPAN><\/P><\/TD> Line length automatically calculated by database.<\/SPAN><\/SPAN><\/P><\/TD><\/TR> SEGMENT_ID<\/SPAN><\/SPAN><\/P><\/TD> Unique Segment ID<\/SPAN><\/SPAN><\/P><\/TD> Long<\/SPAN><\/SPAN><\/P><\/TD> LINE_WIDTH<\/SPAN><\/SPAN><\/P><\/TD> Line Width<\/SPAN><\/SPAN><\/P><\/TD> Text<\/SPAN><\/SPAN><\/P><\/TD> 20<\/SPAN><\/SPAN><\/P><\/TD> This classifies line width into three classes, either <3m, 3-7m, or >7m.<\/SPAN><\/SPAN><\/P><\/TD><\/TR> WIDTH_CODE<\/SPAN><\/SPAN><\/P><\/TD> Width Code<\/SPAN><\/SPAN><\/P><\/TD> Long<\/SPAN><\/SPAN><\/P><\/TD> This is the width class of the line feature (3m,5m, or 7m).
