Isopach and Structure Surface Grid Data

Control Points Extracted from Atlas Structure Surface Files

These files contain data from SurfaceII (SII) and CPS3 grids generated from the Western Canada Sedimentary Atlas project and are suitable for input to gridding and contouring software. The records are for nodes in the grids from which the contours were drawn. They do not deal with boreholes directly.

  • The SII grids (structure and isopach) were generated on atlas point data.
  • The CPS3 grids (structure only) were generated on the back modeling of the published contours.
  • All point sets are located in geographic coordinates (decimal degrees), the elevation or thickness values are in metres.

Quality Control

  • The back modelled grids were checked to see if they resulted in contours which reasonably overlaid those in the printed volume. Except in areas of low slope, at saddle points and near the edges of the contoured areas, they overlay well.
  • The atlas control points were compared to both the original grids and the back model grids. The correspondence was variable. It was especially poor in areas where relief varied rapidly. This is, in part, because of the heavy averaging used in production of the original grids.

For ease of importing, the below files do not have column headings. The headings for each file are

Position (4th quarter degrees)

  • longitude NAD 27
  • latitude NAD 27

Elevation or thickness (m)

  • value
