File formats for spatial data

This chapter documents the DB2 Spatial Extender well-known representations. The representations are described as well-known because they are provided by ESRI and are not specific to DB2 Spatial Extender. Three kinds of spatial values are important to understand for the importing and exporting of spatial data:

• The Open GIS Consortium (OGC) well-known text representations
• The OGC well-known binary (WKB) representations
• The ESRI shape representations
