[talk-au] Mapping Coastlines (Was: Re: Boundary removal.)

[mick]

Is there not an Official Datum for tide heights, I vaguely remember reference to it in a project I was involved in back in the early 1990's.

Failing that, are the GeoScience Australia Topo 250k series maps an acceptable source? I have the complete digital set here as either ESRI shape files or MapInfo tabs. From memory the mapping ranges from 1973 to 2001 and publication dates to 2006.

According to the website ( https://www.ga.gov.au/products/servlet/controller?event=DEFINE_PRODUCTS ) the data is released under Creative Commons Attribution 3.0 Australia Licence.
