Towards a generic method for buildings-parcels vector data adjustement by least squares

9th International Symposium on Spatial Data Quality (ISSDQ'2015) - sep 2015

Being able to merge high quality and complete building models with parcels data is of a paramount importance for any application dealing with urban planning. However since parcels boundaries often stand for the legal reference frame, the whole correction will be exclusively done on building features. Then a major task is to identify spatial relationships and properties that buildings should keep through the conflation process. The purpose of this paper is to describe a method based on least squares approach to ensure that buildings fit consistently into parcels while abiding by a set of standard constraints that may concern most of urban applications. An important asset of our model is that it can be easily extended to comply with more specific constraints. In addition, results analysis also demonstrates that it provides significantly better output than a basic algorithm relying on an individual correction of features, especially regarding conservation of metrics and topological relationships between buildings. In the future, we would like to include more specific constraints to retrieve the actual positions of buildings relatively to parcels borders and we plan to assess the contribution of our algorithm on the quality of urban applications results.
