The street records of the State Digital Road Network (SDRN) baseline dataset have been generated from road casement boundaries of the QLD Digital Cadastre Database (DCDB)and updated where more accurate source data has been available. Other sources used in the maintenance of the streets dataset include aerial imagery, QLD Department of Transport and Main Roads State Controlled Roads dataset, supplied datasets from other State Government Departments, Local Government data, field work using GPS, and user feedback.
