I really enjoy this! I wish it would also support cities, it would help me get a better sense of the size of a city to compare it to one I'm familiar with already. But I guess city limits are less well defined that country limits. Anyway, great project!
Surely any city is small enough that projection distortion is negligible? So you can just open cities on two maps side by side and zoom in/out till the scales are equal.
That site only seems lock the zoom value of the two maps together, not correct for distortions. E.g. zoom in on Svalbard on one side and the Democratic Republic of the Congo on the other. Svalbard appears larger despite being many times smaller. This means if you zoom into Longyearbyen it will appear several times larger than it should compared to say Kinshasa.
Longyearbyen is a pathological example but it's quite easy to end up thinking a city in the UK is ~1.75 linearly and ~3x by area compared to one on the equator using this site.
same here, I was looking for a tool that does exactly that a few weeks ago. Ended up just comparing 2 google maps with same zoom level, but it's not practical at all. Open to any suggestion you may have!
