Does the ERDAS APOLLO Catalog replace the GeoMedia Catalog Editor Utility?
No, ERDAS APOLLO Catalog does not, and there are no plans to, replace the GeoMedia Catalog Editor.
ERDASAPOLLO Catalog was built to extract metadata from data and provide access to data.
GeoMedia Catalog Editor was built solely for metadata compliance to XML/ISO profiles and supporting update workflows.
Even though the GeoMedia Catalog Editor last version was 2013, metadata catalog support is till in the GeoMedia.
Where can I find this Geomedia Catalog Editor Utility in Geomedia 2018 ?
It is not available, it was deprecated several years ago. - Hal
So how can we edit Geomedia Catalog entries now ?
There is no means to do so. - Hal
