It's a good link; also cited nearby is: http://www.ga.gov.au/oracle/#topo I think Geoscience Australia may not cover the Australian state of Tasmania at the same level of detail as portions of the Australian mainland? It looks like even most of the mainland is not in their database. For example this image shows available region data and Tasmania is not covered: http://www.ga.gov.au/image_cache/GA3461.jpg I am also not sure about the resolutions they have. I would like 1:25000. They do have some 1:100000 data for a narrow chunk of geography not including Tasmania: https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&catno=64002 Also I'd like something searchable that can synthesize a dataset for me. There does seem to be some DEM/elevation data such as at the link below; but it's just a search interface that yields "some files that the system could find in the area" not really a synthesis of everything in the specified region: http://www.geoscience.gov.au/bin/mapserv36?querymode=&mode=browse&zoomdir=1&INPUT_TYPE=auto_rect&INPUT_COORD=115%2C12%3B350%2C229&qlayer=oq&map=%2Fpublic%2Fhttp%2Fwww%2Fgeoportal%2Fgadds%2Fgadds.map&zoomsize=4&mapsize=440+270&imgxy=219.5+134.5&imgext=142.049233+-44.754147+150.647600+-39.468136&map_width=440&map_height=270&min_x=142.049233&min_y=-44.754147&max_x=150.647600&max_y=-39.468136&layer=dem There is however a nice new WMS server - excruciatingly slow but pretty as heck: http://mapconnect.ga.gov.au/MapConnect/imf.jsp?accept_agreement=on&site=MapConnect And sadly it requires you to heh - confirm a license that the data is free - and then crashes because the license url is missing. So downloads of extracts fail. Oh well. I told them their site was borked. I wonder if Australia has the best data in the world about Australia. What about the GTOPO30? http://edc.usgs.gov/products/elevation/gtopo30/gtopo30.html http://edc.usgs.gov/products/elevation/gtopo30/e140s10_tile.html What is the best data in the world that we can get our hands on? Is there one place that has a perfect collection of all free data? ;-) - a _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
