Description
When generating lists of tile ids covering geometries we are seeing a difference between the tile-cover and the rs cover generated tile ids. For the same geometries:
wc -l /tmp/tile-cover.tiles
116230 /tmp/tile-cover.tiles
wc -l /tmp/rs-cover.tiles
115248 /tmp/rs-cover.tiles
Our rs cover tool does not include 982 tiles the tile-cover tool gives us. We need to look into this.
Tasks:
- Figure out difference between
tile-coverandrs cover

Research direction
Start by reproducing the comparison between the tile-cover output and the rs cover output for the same geometries, using the reported wc -l counts. Inspect the rs cover entry point and compare its tile list with tile-cover to identify the 982 missing tiles. Done means the discrepancy is explained and, if appropriate, the two tools produce matching coverage.
