Statement

Dataset Source: Original data came from Division of Survey and Mapping's VICBASE. This is 1983 Digital Map of Victoria which was formed using the AUSLIG 1:250000 as its base control. Apparently the 1:250000 maps were reduced to 1:500000 and then digitised as a training exercise by Division of Survey and Mapping. Dataset Originality: Primary
