This study applies decision analysis techniques for the qualification of economic value of the a high intensity Soil Survey of Sentinela do Sul County, RS, Brazil (scale 1:50,000) and a soil survey of the Charcoal Basin of the Jacuí River, RS, Brazil (Scale 1:100,000), using economic information related to the major regional crops and soil survey quality. The determination of the economic value is made by quantifying the increase in economic return when land use planning uses soil survey information. Results of this evaluation highlight the economic benefits generated by the use of soil survey information (R$153,15 ha-1 e R$70.15 ha-1, respectivelly for a 1:50,000 map and for a 1:100,000 map) are larger that soil survey costs (R$1.03 ha-1 for a 1:50,000 map and R$0.38 ha-1 for a 1:100,000 map).
