  4. 4. Western Canada DLS Grid !  ~1,500,000 km2 (or about 10 Englands) !  ~10,000,000 polygons
  5. 5. Western Canada DLS Grid
  6. 6. Defintion: “Road Allowance” !  20m or 30m separation between sections !  Surveyed sections from 1871 to 1880 all have road allowances !  Surveyed sections after 1881 reduced by half the number of East/West road allowances !  Not all road allowances have a constructed road

  18. 18. First Pass !  Meridian lines with variable distances and problems !  Known areas missing grid !  Holes caused by misaligned vertices !  Decision to use summer students to correct holes
  19. 19. How to validate manual work? Use FME!
  20. 20. Great Scott! Holes Everywhere!
  21. 21. Multi-Step Process !  Add Sliver Remover to main workspace !  Re-evaluate whole process and split into sections for performance
  22. 22. Coordinate Rounder
