Figure 4.
The flow direction map covers the Auckland region from approximately 35 degrees 50 minutes south to 37 degrees 30 minutes south and 173 degrees 50 minutes east to 175 degrees 50 minutes east. The legend classifies flow direction values as 1, 2, 4, 8, 16, 32, 64, and 128 within the regional boundary. These flow direction classes form dense, branching patterns throughout the mainland and surrounding islands, tracing drainage pathways across the region. A compass indicates north, east, south, and west. The scale bar extends from 0 to 100 kilometres, with marks at 12.5, 25, 50, 75, and 100 kilometres.Flow direction
