Hello guys!
I found OpenHistoricalMap recently, and I'm having a great time with it.
I'm from Rio de Janeiro, and my first goal is to map the various lines of
trams we had in the city until the 1960s.
This work has been easy, but I have faced some problems. Since I didn't
find answers in FAQs or similar things, I forward my doubts.
1. How do I map changes on the coastline? The history of Rio in the 20th
century is marked by numerous embankments on the waterfront, so the map
would be more interesting if it were possible to reproduce these changes.
1.a. Same for ponds and piped rivers. What should I do to reproduce these
changes over time?
2. One of the railroads I am mapping was built in 1878, but was not
electrified until 1945. Is there any way to insert two time frames into the
same object?
2.b. One of the trolley lines I mapped has been converted into a heavy
railroad track. Should I map two overlapping lines or is it possible to
time differentiate them using tags?
Thank you for your attention.
