  1. it would be useful to see in each PR what's different to the currently published version
  2. it would be useful to see what's changed in each result run automatically by machine

If a ton of things have changed, how would you want to see a very large diff?

on a map, but there are varying levels of how well integrated it would be. ranging from:

  1. just providing a script which accepts two outputs and produces a diff CSV
  2. providing a diff csv as part of the results
  3. providing a slippy map of the diff

with the diff containing

  1. new addresses marked INSERT green
  2. removed addresses marked DELETE red
  3. changed addresses marked MODIFY orange. Though detecting this isn't straightforward. It could be based on everything remaining constant except the geometry or vice-versa geometry is constant but some attribute changed value...

Thanks — I think it’d be possible to work with these ideas. I’m unsure of the time commitment required, but this is all technically possible!
