Georeferencing is one of the most important stages of digitizing analogue maps. It isaffected by many factors such as; scales and resolutions of maps, the number ofcontrol points, etc. In this study, four of these factors were investigated using 2 4factorial design in two dimensional georeferencing of cadastral maps. Factorialdesign determines, whether the selected factors have main and/or interaction effectson a response variable or not. Map scale, resolution of raster map, the number ofcontrol points and the coordinate transformation method were selected asexperimental factors. Then, main effects and interactions between these factors wereinvestigated. The results were statistically analyzed using analysis of variance(ANOVA), and a regression model was suggested to consider the significant mainand interaction effects of factors. It was observed that the two dimensionalgeoreferencing of maps were affected by each of the selected experimental factorsand by the interaction between the map scale and coordinate transformation method.
