4. Repeat this process for the osopenroads files (since some addresses are linked to only gb1900 and some only to osopenroads).

3. The scot_1851_gb1900_recidlkup.tsv file provides a bridge between the recids in the I-CeM file you've downloaded to the gb1900 map data in the scot_1851_gb1900.tsv. Once linked, you can map any of your variables in the downloaded I-CeM file using the geometry data in the scot_1851_gb1900.tsv file

2. Link the 'recid' field in your Govan I-CeM data to the 'recid' field in the scot_1851_gb1900_recidlkup.tsv file. Then link the 'gb1900_uid' in the scot_1851_gb1900_recidlkup.tsv file to the 'gb1900_uid' field in the scot_1851_gb1900.tsv file.

1. Download the Govan 1851 data from icem.ukdataservice.ac.uk
