Old geological maps were stored as paper maps and thus need to be digitized when integrating them into digital geographic information systems. Metadata is required to find relevant maps fast. However, metadata is usually created manually with a lot of effort. We present work in progress for a semi-automated approach for extracting metadata from maps. The results show that it lowers the manual effort significantly to extract the location and improves at least the experience of the manual annotation with respect to date metadata.enNLPMetadataOCRgeological mapsText/Conference Paper10.18420/inf2023_1711617-5468
