How To: Export geodatabase annotation to an ArcInfo coverage with a valid extent
Instructions provided describe how to export a geodatabase annotation feature class to coverage annotation.
The invalid extent for the annotation coverage occurs because annotation is not a 'real' feature, has no topology, and when exported to a coverage, ArcInfo does not have a way to determine the coordinate extent of the annotation feature class. The result is the unusable extent of the annotation coverage.
There are two ways of exporting the annotations:
- Option 1:
Export both the annotation and a 'real' feature class, containing point, line or polygon features, from the database into the same coverage with the annotation. The 'real' features provide a proper extent for the output coverage.
It may be necessary to start an ArcEdit session, and modify the $SIZE pseudoitem for the coverage annotation, if the coverage annotation output is too large, and does not display properly in ArcMap.
- Option 2:
1. Add the annotation feature class from the geodatabase to a new, empty ArcMap session.
2. Open Layer Properties > Source tab, and copy the coordinates for the extent of the annotation feature class.
3. In ArcInfo Workstation, use the GENERATE > Polygon command to generate a polygon coverage which has the same extent as the annotation features, copied above in ArcMap.
4. BUILD the new polygon coverage at the Arc: prompt.
5. Use COPYFEATURES to copy the annotation feature class from the annotation coverage into the polygon coverage.
6. At the Arc: prompt, issue the REBOX command.
7. Use PROJECTDEFINE to define the projection for the polygon coverage, which now has polygon and annotation features.
8. At the Arc: prompt, BUILD the coverage for polygons and the annotation feature class.
Again, it may be necessary to start an ArcEdit session, and modify the $SIZE pseudoitem for the coverage annotation, if the coverage annotation output is too large, and does not display properly in ArcMap.
