The following spatial data (shapefiles) and attribute data (Canada Census) were obtained from the SIS network under S: Drive’s Data Warehouse folder

The following spatial data (shapefiles) were achieved by manually creating point features on ArcMap. Google Map was used to determine the spatial locations of the existing hospitals, libraries, and shopping centre. juststreet2.shp was use as reference material to create point features on the shapefiles. Point and polygon features were created using the Editor Tool in ArcMap.

        • hospital.shp
        • library.shp
        • shopping_centre.shp

To complete the project, the below softwares were extensively used:

        • ArcCatelog
        • ArcMap
        • Dreamweaver
        • IDRISI
        • Micsoft Paint

DATA MANIPULATION WITH ArcMap and IDRISI

Only the area of GVRD were kept from the BC_UTM10n.shp, making it the base map (called BC_UTM10n_basemap.shp) of the project. The attributes table of the base map and the Census data are then joined (field DAUID), and exported into thematic map shapefiles. The following shapefiles with Census data were created:

        • employment_rate.shp


        • average_income.shp


        • total_population.shp


        • transit_users.shp


Other than people who are taking public transit, people with mode of transportation of bicycle, walking, and other method were included as well since they have higher demand than those who drive. A new field of transit users was created, with addition of various columns of in the field calculator.

These shapefiles were projected into UTM 10N reference system and imported into IDRISI using the SHAPEIDR module.

After the Census maps were imported into IDRISI as vector images. Desired field (employment rate, average income, total population, transit users) of each image was selected and used to create a new raster image.

Image Calculator was used to calculate the population density. Mathematical expression was selected with the following equation:

population_density = [total_population_totpop]/[total_population_totpop_area]

where

        • total_population_totpop = raster image of total population
        • total_population_totp_area = raster image of area created using AREA module


Spatial shapefiles were projected into the UTM 10N reference system as well and then imported into IDRISI through the SHAPEIDR module. These vector images were then converted to raster format using RASTERVECTOR module.
