[edit]

I created this page because it seemed to be a gaping hole in the coverage of GIS on Wikipedia. It's a good start, but it could use further enhancement:

  • More detailed history? I once saw a conference talk showing McHarg's transparent overlay technique in a Nazi-era German agriculture journal, but I can't find it now.
  • More details on the algorithm, including a good citation
  • Implementation in other software, such as spatial SQL extensions
  • More about overlay with lines and points.
  • An applications section with several examples
  • Should Spatial join and Spatial query be part of this page, or should they have their own pages? They are not anywhere else and they are overlay in a sense.Bplewe (talk) 01:20, 27 October 2021 (UTC)[reply]
