Release Notes

mapbox/rasterio

v1.2.9

Compare Source

• Compute geometry_window more accurately and tightly for rotated rasters,
  fixing a regression introduced in 1.2.1 (#​2303).
• Copy mask to destination in rio-clip and rio-convert (#​2232).
• Use a default 70% confidence threshold when matching CRS to definitions in
  authority files (#​2293). The confidence threshold can be defined when calling
  to_epsg and to_authority, which partially addressed the issue reported in
  #​2290.
