Talk-au, I am pleased to introduce new grayscale imagery for all of Australia at 2.5 metre resolution.
“The Australian Geographic Reference Image” is produced by Geoscience Australia and made available under Australian Creative Commons Attribution 2.5. http://agri.openstreetmap.org/ JOSM tms url: tms:http://agri.openstreetmap.org/{zoom}/{x}/{y}.png Potlatch background url (Background > Edit> Add): http://agri.openstreetmap.org/$z/$x/$y.png (Will be added to Potlatch imagery default in a few days.) Recommended source tag: source=AGRI The positional accuracy seems to be excellent. I have already used the imagery to add a few missing railway line sections in Western Australia. It takes a little while to get used to the imagery being grayscale. In JOSM I’ve found it helpful to add some colour to the imagery by overlaying the imagery over a Bing background with AGRI layer set slightly transparent. Geoscience Australia’s IP and Copyright Manager has confirmed that the attribution requirement does NOT carry through to tracings derived from the aerial imagery. Quote: “The attribution requirement does not have to carry through to the tracings from the aerial imagery.” - IP and Copyright Manager, Geoscience Australia The service is very much in beta at the moment and may go offline for testing and revision at times. It will also likely take me a few weeks to fix the black overlap issues. I’ll also make the 2950GB of source imagery files available once I have worked out a suitable hosting arrangement. Thank you to: - Andrew Harvey for pointing out that the imagery was available: http://lists.openstreetmap.org/pipermail/talk-au/2012-February/008919.html - OSMF for supplying hardware + funding for the purchase of the imagery. - Geoscience Australia Happy mapping.
