The individual 25K model tiles were aggregated into two sets one for the TL sheet and one for the TM sheets as described above, these were subsequently merged into the complete model in 2011 which covers approximately 500 sq km of land area. Consistency between tiles was achieved by the use of docker sections iterated between the two tiles and then envelope merging using the polygon editing tools. The final workspace was assembled to include all sections, standard, helper and dockers, merged envelopes for all units, and a regional Nextmap 50m dtm supercede by the BGS Bald Earth model.
