<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset displays the man-made canal</SPAN><SPAN> </SPAN><SPAN>areas (canal estates, drains, channels) covering eastern Queensland. The area covered includes all the east coast drainage basins from the South Coast Drainage Basin (NSW border) to the Endeavour Drainage Basin (Cooktown) as well as the Fitzroy, Burdekin and Murray Darling Drainage Basins. The canal area feature is shown when a canal exceeds a set width and is dependant on scale of the data. (e.g. for 25000 data, canals are greater than 30 metres will be shown as a canal area. For 50000-100000</SPAN><SPAN> </SPAN><SPAN>data, it will be those canals greater than 60 metres wide) A connector feature flows</SPAN><SPAN> </SPAN><SPAN>through canals areas to create a continual linear network for hydrological modelling.</SPAN><SPAN> </SPAN><SPAN>Features are attributed with names where available. Features have been captured or updated from the best available imagery with an attribute within the data describing the source and reliability. Those features within the coastal drainage basins have been captured at 1:25000 mapping specifications, while those features within the Fitzroy, Burdekin and Murray Darling Drainage Basins have been captured at 1:100000 mapping specifications.
