> On the other hand, my understanding is that the WKB Geometry used in the covering statistics is not a bbox. It's not necessarily one; however, the cheapest possible way to build a bbox covering would be to build a bbox from the input and convert it to a POLYGON. Similarly, the cheapest possible way to push a filter down into the WKB-encoded covering would be to compute the bbox of the WKB-encoded covering and use that. In the Java implementation it seems like you can lean on JTS for all of this (in C++ we probably don't want to invoke any actual geometry libraries). -- This is an automated message from the Apache Git Service.
