### Local vs. Regional CCI  
Each of the counties analyzed is characterized by an overestimation of the area of maximum compliance by regional CCI compared to local CCI. The largest growth of maximum data compliance takes place in Otwocki and Piaseczno counties, amounting to 50.9% and 40.1%, respectively, and the lowest in Miedzyrzecki (16%) and Slupski counties (14.7%). The overestimation of a very good match between BDOT10k and OSM does not depend on the spatial extent of the region, i.e., it does not change when counties are added and the extent of the region increases. The upsurge in maximum data compliance was at the expense of a moderate compliance class, showing an average of 17.2% (the highest, 29.8%, in Otwocki and the lowest, 6.8%, in Miedzyrzecki counties), and that in comparable data agreement (semi-conformance class) showed an average of 8.2% (the highest, 12.2%, in Otwocki and the lowest, 4.1%, in Slupski); low and very low compliance classes (moderate and maximum non-compliance) increased by 3.5% and 1.9%, respectively. The maximum decline in the area considered non-compliant occurred in Piaseczno and Otwocki counties. However, their extents do not exceed 9%.
