I'd like to overlay the cities of Europe on Australia for distance/size comparison purposes using QGIS and I'm wondering how best to achieve this while preserving distance between the European cities?
It's somewhat roundabout, and I don't know how you'd implement it in QGIS, but I'd try:
- Flip the sign on European latitude values,
- Shift the Europe longitude to center on Australia,
- Define two conic projections using the same central meridian but different standard parallels for Australia and flipped Europe
- Override the flipped Europe projection with the Australian projection
From there, you might flip north to south through the central parallel, but the distances would be compromised by that process.
It would also be possible to flip longitudes about a central meridian in step 2, which might be less disorienting.
- Either deproject the European shapes to GCS_WGS_1984 or project the Austrialian data to the conic projection for apples-to-apples comparison.
