Association between our proposed industrial land area ratio (%) and the official data-based industrial land area ratio (%) for six representative cities. Ratios were calculated within a 5 km grid inside city boundaries. Official industrial land data were rasterized to 30 m from the original vector file. Port/airport areas in Singapore and semi-industrial areas in Nagoya, classified in the official data, were excluded from both datasets for calculation due to mixed land use. The grey line represents the linear regression, with the correlation (r) indicated.
