Data Collection
Data for this project were collected from the following sources.
ArcView Components
1. Spatial Data (shape files): SIS network under S drive's Data Warehouse
folder
|
a. Enumeration
areas.shp
Query builder was used to select only Vancouver, Burnaby, and New Westminster.
They were prepared to work with Census EA data.
|
b. Muni.shp
Three municipalities were compiled together using Summarize merge function.
This was later then used to convert to raster.
|
c. GVRD_1996_landuse.shp
The land use for only three cities were extracted using Select by theme
function (intersect).
|
d. Majorroads.shp
Major road network of GVRD was obtained.
|
e. hospitals.shp
Twelve hospitals in Vancouver, Burnaby, and New Westminster were digitized
in ArcView.
|
2. Attribute
Data for 1996 Census variables: Research Data Library (http://www.sfu.ca/rdl/)
|
a. Age
(Profile of enumeration area)
CAP table of Part 1: Age and Sex and Families was downloaded and modified
in Beyond 2020 in order to transpose the data. Then it was saved as
.dbf to work in Microsoft Excel.
|
b. Income
(Profile of enumeration area)
CAP table of Part 8: Sources of Income was downloaded and modified in
Beyond 2020 in order to transpose the data. Then it was saved as .dbf
to work in Microsoft Excel.
|
c. Population
(Profile of enumeration area)
CAP table of Part 1: Age and Sex and Families was downloaded and modified
in Beyond 2020 in order to transpose the data. Then it was saved as
.dbf to work in Microsoft Excel.

| 1. Average
Age |
There were
23 different age categories for male and female. In order to find the
average age for each EA, the number of people for each age category
was multiplied by the median age for that category (46 categories all
together). Then, those numbers were added all together for each EA.
Later, they were divided by total male and female to find the final
average age for each EAs. The average ages for the study areas, Vancouver,
Burnaby, and New Westminster, were joined to the theme table based on
EA numbers after creating a new field, average age.
|
| 2. Population
Density
|
Population
data, which was modified in Beyond 2020 was joined based on EA numbers
in the theme table of the EA shape file. Then a new field, population
density, was created. Using Calculate function in ArcView, total population
for each EA was divided by area (m2) in order to find population
density.

1. Converting
vector to raster
The following shapefiles were converted to ascii raster format in ArcView
and then imported as rasters in Idrisi.
|
a. Muni.shp

|
b. Landuse.shp

|
c. Majorroads.shp

|
d. hospitals.shp

|
e. age96.shp

|
f. income96.shp

|
g. density96.shp
