Other effects of SCAM

• Previous example has shown the ‘single table’ effect of SCAM

• There are also problems when comparing:

• (a) flows between tables at one scale

• (b) flows between tables at different spatial scales

• because SCAM is applied independently to each table at each level

Notes:

The previous effect gives an indication of the ‘single table’ effect of SCAM but SCAM also creates problems when we want to compare (i) flows between tables and (ii) flows between spatial scales.
