Abstract :
Automatic evaluation of drawing-to-CAD conversion performance is addressed. The generating model of artificial images in the domain of cadastral maps was built. The proposed model was close to the authentic drawings on the level of graphic primitives and on the level of map understanding. The shape of the parcel was characterized by the number of corners, line lengths and respective angles. The model of a house consists of 12 random variables, while the 13th variable describes the location of the house in a parcel. The parameters of probability distributions have been estimated from the sample of 115 parcels and 127 houses. The goodness-of-fit for all distributions was very high
