The generalization by simplification operator with Chrobak’s method of objects representing groups of buildings in Gdańsk district - scale 1:25000

Description

The process of automatic generalization is one of the elements of spatial data preparation for the purpose of creating digital cartographic studies. The presented data include a part of the process of generalization of building groups obtained from the national geodesy and cartography resource from BDOT10k (10k topographic database) [1].

The input data are building groups obtained as a result of the aggregation operator activity (GDA_BuildingAggregation). The Chrobak's operator was designed to simplify lines [2]. For the purpose of simplifying buildings, this method has been adapted and extended by verifying the minimum size of the object using the cartographic matrix [3]. The resulting objects require another stage - orthogonalization. As a result of the simplification process, 1.5% of building groups have been removed.
