In this study, two different GIS-based nominal land value maps have been created in Avanos district of Nevşehir province. One of the land value maps (Model-1) was created using factor scoring and weights that accepted in the literature. On the other hand, for the 2nd land value map (Model-2), factor scoring was not performed based on the literature entirely; instead, it was partially changed by taking the local characteristics of the study area into consideration, and by using our expert experiences in the region. In addition, for Model-2, weighting was made via the Analytical Hierarchy Process (AHP), by taking the local characteristics of the study area into account. After the nominal land value maps were created, they were converted into parcels and indexed according to the unit values obtained from the current values and converted to TL. When the nominal values were compared with the current values on a street basis, it has been observed that Model-1 which was produced according to the literature has a compatibility rate (approximately) of 79%, and Model-2 which was produced by considering the local features has a compatibility rate of (approximately) 88%. Finally, the tax values collected from the relevant municipality and the current values were compared on a street basis and it was concluded that the tax values were found significantly different than the current values.
