########## format/spec.md: ########## @@ -483,6 +485,8 @@ Notes: 2. For `float` and `double`, the value `-0.0` must precede `+0.0`, as in the IEEE 754 `totalOrder` predicate. NaNs are not permitted as lower or upper bounds. 3. If sort order ID is missing or unknown, then the order is assumed to be unsorted. Only data files and equality delete files should be written with a non-null order id. [Position deletes](#position-delete-files) are required to be sorted by file and position, not a table order, and should set sort order id to null. Readers must ignore sort order id for position delete files. 4. The following field ids are reserved on `data_file`: 141. +5. For `geometry`, this is a point. X = min value of all component points of all geometries in file when edges = PLANAR, westernmost bound of all geometries in file if edges = SPHERICAL. Y = max value of all component points of all geometries in file when edges = PLANAR, northernmost bound of all geometries if edges = SPHERICAL. Z is min value for all component points of all geometries in the file. M is min value of all component points of all geometries in the file. See Appendix D for encoding. Review Comment: Personally, I'm good with geodesic; however, there were others that brought up concerns with that term in the GeoParquet group meetup and were more comfortable starting with pseudo-geodesic. I don´t remember the exact details of the issue. Perhaps @paleolimbot, @jiayuasu , and/or @desruisseaux can chime in with their perspectives on it. -- This is an automated message from the Apache Git Service.
