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:
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.
Note: 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.
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.
Note: 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.
