public class OGCESRIShape extends java.lang.Object implements Shape
POLYGON ((-89 43,-89 50,-97 50,-97 43,-89 43))
The binary representation can be generated from PostGIS by selecting
the geom column using a normal select statement. When a shape is parsed, we
detect the format and use the appropriate parser. When writing to text, we
always use the binary representation as it is faster and more compact. For
binary serialization/deserialization, we use the PostGIS writer and parser.Modifier and Type | Field and Description |
