Objects resulting from the sequential generalization of the buildings group in Gdańsk district - scale 1:10000

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 provided data are the result of the last stage of building groups sequential generalization process. During the process, objects with the highest average coefficient values were selected from three methods of data simplification (Chrobak’s method - GDA_OrthogonalizationChrobak, Sester’s method - GDA_OrthogonalizationSester and the Simplify Building tool - GDA_OrthogonalizationArcGIS) for a group of buildings with the same identifier, while eliminating those objects that had a value of -1 in one of four coefficients.
