1Spatial: Edinburgh FME World Tour: Maintain a national buildings database
0 likes•53 views
This document discusses how FME software helps create and maintain a national buildings database in the UK called UKBuildings. It allows non-SQL experts to easily load, integrate, validate, and publish building data from various sources. FME is used to load data into a PostGIS database, create and integrate attributes, validate data quality, and link buildings to other datasets like addresses. This process provides a consistent and reliable way to update the database with new data and publish the buildings information in different formats.
