Figure 1.15
Example of blockface and dissemination block representative points

Figure 1.15 is a graphic representation of blockface and dissemination block representative points.

The illustration is made up of a fictional grouping of streets and dissemination blocks. Dissemination blocks appear as polygons. Each dissemination block contains blockface representative points, which are represented by a small "x" and are centred on the inside of each blockface. Each dissemination block also contains a dissemination block representative point located in the centre of the dissemination block, which is represented by a large, bold plus sign (+).

In the bottom right quadrant, two dissemination blocks are crossed diagonally by a census subdivision (CSD) boundary. To respect the dissemination area geography, the CSD boundary splits each of the dissemination blocks that it crosses, thus creating two dissemination blocks out of one. Each of these dissemination blocks contains a dissemination block representative point located in its centre.

Finally, most dissemination blocks in this graphic contain a series of small polygons, shaded light grey, that represent dwellings.

Below the figure is a legend that demonstrates the symbols used to represent blockface representative points, dissemination block representative points and the CSD boundary.
