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 data cover the spatial range of Kartuzy district. In the district there are buildings of almost every class according to the BDOT10k classification except BUBD20. Single-family residential buildings account for 61% of all buildings, farm buildings for 31%, each of the other classes contains less than 2%.
The provided data include original data downloaded from geoportal.gov.pl (on 6 November 2020) [2] as well as processed data. The aggregation process was performed taking into account the proximity of the neighborhood [3] based on the minimum size of the figure [4, 5]. The data are the basis for the subsequent steps in the process of sequential generalization of building groups.
