Slow-proofed and worth the wait. Worth its weight in flour.
Summary
The article discusses the technical challenge of computing simplified geographic polygons, specifically simplified hulls, for various applications where meter-resolution geometry is unnecessary and higher resolution comes with storage and transfer costs. The author presents an overview of current approaches and seeks better algorithms for this recurring problem in their work.
Key quotes
· 3 pulledA somewhat recurring problem I encounter in things I work on is the need to compute simplified geographic polygons, or more specifically, simplified hulls of geographic polygons.
Meter-resolution geometry isn't needed for any of those use-cases, hundreds of meters or even a kilometers are more than sufficient.
And using a higher resolution does come at a cost, larger geometry needs to be stored and transferred.
