Remarks
Metadata
Available metadata keys :

|---|---|---|---|
| TGIS_LayerSHP.SafeFieldName | TRUE FALSE | FALSE | False force shorter field name size. Due to some misunderstanding, some application accepts 11 characters names while others accept only 10 characters. |

Limitations
Geometry limitations:
- 2 GB size limit for any shapefile component file
Attribute limitations:
- store numeric attributes in character format rather than binary format
- The dBASE file standard only supports ANSI characters in their field names and values
- Date fields only support date,not support time
- Field names cannot be longer than 10 characters
- The maximum record length for an attribute is 32767
- The maximum number of fields is 255
- The dBASE file must contain at least one field
- Null values are not supported
Shape types
Mixing shape types is not allowed. For example, when concerning wells (point), rivers (polyline) and lakes (polygon), they must be stored in three separate shapefiles.
Error codes
During some operations, “File … has wrong format or was corrupted” exception is raised with a code referring to known limitations:
| Code | Description |
|---|---|
| 65536 | The maximum buffer size of geometry exceeded |
| 32767 | The maximum buffer size of attribute exceeded |
