This topic contains information on the Oracle spatial data types supported for import via the Open Data Import Centre.
Spatial Geometries Supported for Import
The following Oracle spatial geometries are supported for import:
|
Spatial Data Type |
Import Comment |
|---|---|
|
Point |
- |
|
Oriented Point |
Orientation vector is ignored |
|
Multi-Point |
First point only imported |
|
Point Cluster |
First point only imported |
|
Line String |
Line strings where points are connected by arcs are converted to straight lines with multiple points added along the arc. |
| Compound Line String | Arc lines are converted to straight lines and the straight lines are imported as a normal line string. |
|
Polygon |
Supported where the boundary is connected only by straight lines or where it is a rectangle |
|
Multi-Polygon |
First polygon (connected by straight lines or a rectangle) only imported |
|
Collection |
First compatible element only imported (if present) |
The following Oracle spatial geometries are partially supported for import:
