Upgrading to RGeo Version 3.0

Here's a checklist of things to change when upgrading to RGeo 3.0. For a comprehensive list of changes, see History.md.

  • Remove uses_lenient_assertions and uses_lenient_multipolygon_assertions flags from factory creation.
  • If your app requires predicate or analysis methods (ex. contains? and area) to be called on invalid geometries, you may want to consider using the unsafe_* variants of those methods to skip the validity check. See Geometry-Validity.md for more detail.
  • Remove boundary calls on GeometryCollections
  • Remove all is_*? methods and replace with the *? versions.
  • Remove SRSDatabase usage
  • Change proj4 options to coord_sys or use the EPSG SRID in the srid option for factory creation.
  • Rename instances Geographic::Proj4Projector to Geographic::Projector and use coord_sys instead of proj4 during creation.
