GeoCoordStatus Enumeration
This enumeration lists all possible status as returned from a coordinate conversion to or from a
GeographicCRS and either another GeographicCRS or a GeodeticDatum.
see the PointWithStatus included in an IModelCoordinatesResponseProps or GeoCoordinatesResponseProps.

| Name |
Value |
Description |
| Success |
0 |
Indicates successful coordinate conversion. |
| OutOfUsefulRange |
1 |
This value indicates that the conversion was performed outside of the normal use of application of either Geographic Coordinate Reference Systems.
This return value can often be treated as a warning in specific cases. For example, global imagery extent spans the whole globe and
may extend far beyond the normal area of the iModel project extents and the extent of normal use of its Geographic Coordinate Reference System.
In such cases this value can be considered a warning as accuracy and precision is not expected in this specific case and approximate localization
of global imagery or other low accuracy context data is not essential far from the project.
If this status is returned for high accuracy data then it indicates that either Geographic Coordinate Reference Systems were inappropriately selected
for the iModel or other geolocated data. If this is the case the status should be somehow reported so action
can be performed to verify used geolocation parameters.
In either case the returned coordinates are to be considered valid though they may be inaccurate or result in some unexpected distortion of graphical
elements. |
| OutOfMathematicalDomain |
2 |
Indicates a hard error where conversions were requested outside of the area of the mathematical capacity of the conversion process for either
Geographic Coordinate Reference Systems involved. An example could be to attempt a conversion involving a Transverse Mercator more than 60 degrees
East or West of the projection central meridian.
The values returned may or may not be valid and should be discarded. |
| NoDatumConverter |
25 |
Indicates that datum transformation between the two Geographic Coordinate Reference Systems could not be performed.
This error is usually the result of a datum transformation path requiring use of latitude/longitude grid shift files that could not be obtained
or installed. In this case the latitude/longitude transformation is bypassed but the remainder of the conversion process is completed.
This error can be ignored for low accuracy data but should be somehow reported so actions can be performed to provide the missing files. |
| VerticalDatumConvertError |
26 |
Indicates that a problem occurred during vertical datum conversion. This may the result of the inability to access the
Geoid separation data or vertical datum differential data (such as used by NGVD29 to NAVD88 conversion).
The horizontal coordinates returned are valid but the elevation ordinate will be returned unchanged or partially changed.
This status should be somehow reported so actions can be performed to provide the missing information. |
| NoGCSDefined |
100 |
Indicates that the source or target of the conversion is not defined, usually the iModel Geographic Coordinate Reference System. |
| CSMapError |
4096 |
General inner conversion engine error. Coordinates returned are invalid and should be discarded |
| Pending |
-41556 |
This temporary status is used to mark coordinates for which the conversion has not yet been processed by the backend
as opposed to other coordinate conversions that may have been resolved otherwise (typically a cache).
At the completion of the conversion promise no coordinates should have this status. |
