  1. Join GVRDda06SocEcon table to Vancouver_DA, which contains F2 (Population).
  2. Intersect Bus Stop, School Point and Vancouver_DA with Vancouver (Westside) Mask.
  3. Intersect UBC Trail, Stream and Contour (2m) with Pacific Spirit Regional Park Mask.
  4. Self Digitizing a SHP point data for facilities in the Pacific Spirit Regional Park.
  5. Reclassify the DA_PSRP (DA close to Pacific Spirit Regional Park) to 4 classes. QQ20160406-22@2x
  6. Operate Multiple Ring Buffer specifically for the 4 classes of DA polygons as well as the Facilities, Bus Stop and Schools.
    1. DA: 200, 500, 1000, 5000 (m)
    2. Facilities: 200, 500, 1000, 5000 (m)
    3. Bus Stop: 100, 500, 2000, 5000 (m)
    4. Schools: 200, 500, 1000, 5000 (m)QQ20160406-15@2xQQ20160408-0@2x
  7. Convert each vector buffer to raster by using Polygon to Raster tool.
  8. Numericalize the elevation data in contour line’s attribute table.
  9. Create TIN from contour line in PSRP region.
  10. Convert TIN to Raster to generate a DEM.
  11. Use Slope Calculator to generate the slope.
  12. Reclassify the slope into 4 classes.QQ20160406-14@2x
  13. Run the Raster Calculator to operate MCE by using Raster Calculator:
    1. School: 10%
    2. Bus Stop: 10%
    3. Facilities 30%
    4. Slope: 30%
    5. Population Density in Each DA Class: 20%
      1. class 1: 50%
      2. class 2: 30%
      3. class 3: 15%
      4. class 4: 5%QQ20160406-12@2x
  14. Buffer 15m from the UBC trail.
  15. Extract by Mask the generated raw MEC with the buffered trail.
  16. Buffer 50m from the stream in PSRP as the Ecological Sensitive Area.
  17. Clip the Ecological Sensitive Area out from the result.QQ20160406-11@2x
  18. Convert from Raster to Points for the MCE Final Result.QQ20160406-8@2x
