Projections for Australian maps

[edit]

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

[edit]

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.

Billingd/maps is located in Australia

Tasmantid Seamount Chain

[edit]

Maps and tables for Tasmantid Seamount Chain.[3][4][5][6]

Coordinates from GEBCO Undersea Feature Names [1].

Some info on Mellish Reef here [2].

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

[edit]

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.

Test location placement: Cape Howe and Point Danger are the locations where the state borders meet the coast. Errors are approximately 200 km.
