Projections for Australian maps
According to the Australian Intergovernmental Committee on Surveying and Mapping (ICSM) here:
The Lambert Conformal Conic is the preferred projection for regional maps in mid-latitudes. In Australia the national mapping agency prefers to use this projection using 18° and 36° South as the two Standard Parallels. Projection information: Lambert Conformal Conic; centred on 140° East and 25° South, and two Standard Parallels 18° and 36° South.
Cosgrove track
The Cosgrove volcano hotspot track is a theorized chain of volcanoes through eastern Australia.[1][2]
I want to create an image like this. Coordinate data from Davies[1], Extended Data Table 1
Template:Location map+ places one or more location marks on a map, with optional labels. One of the examples is a map of Australia using Module:Location map/data/Australia with base map image Commons:File:Australia_location_map.svg.
OK. Looks OK for a start
Maps with overlays
Looking for examples of maps with overlays:
- Kidepo Valley National Park has an svg overlay.
- map is in a Template:Infobox protected area
- location template is Module:Location map/data/Uganda
- The base map is Commons:File:Uganda_location_map.svg
- the overlay is Commons:File:Kidepo_in_Uganda_location_map_overlay.svg
- Template:Superimpose may be what I want
Play with Uganda example
and with image_overlay added
Tasmantid Seamount Chain
Maps and tables for Tasmantid Seamount Chain.[3][4][5][6]
Coordinates from GEBCO Undersea Feature Names .
Some info on Mellish Reef here .
Another base map is Commons:File:Australasia_and_South_Pacific_locator_map.svg
Here are some Commons:location markers
First attempt at overlay is Commons:File:Tasmantid seamount track overlay.svg

Location map+ | Australia and New Zealand
How accurate are locations on Module:Location map/data/Australia and New Zealand using Template:Location map+ ? Very wrong!! Cape Howe and Point Danger are the locations where the state borders meet the coast. Errors are approximately 200 km.
