I’ve been using OpenStreetMap for a long time, however only today i decided to sign up and volunteer my time to help. I noticed that the beach in Portsmouth, UK was quite inaccurate so decided to edit it. All is perfectly well, however at different zoom levels it to be jagged and incorrect. Any help?
I have also noticed one other thing. I added some pathways to my local park. Again, some zoom levels show what it should look like, and other show it how it was before. Any help?
It takes a while for changes to be re-rendered and the rendering takes place at each zoom level. Usually the changes like your new paths can be seen almost straight away but they do sometimes take a day or so to appear at all levels. Changes to the coast line are a different matter, as the whole thing has to be done its not re-rendered very often. It might take a month for the coast to again look Ok through all zoom levels. Keep an eye on it though.
