An apparatus and a system and a method are provided, to generate a formation model database comprising multiple models, to rotate a downhole assembly that includes a downhole tool comprising at least one antenna pair that determines resistivity data, and to determine resistivity using the at least one antenna pair during rotation of the downhole assembly as part of a downhole operation. During the down hole operation, the method includes receiving the resistivity data; solving for at least resistivity formation parameters using a selected one of the formation models and a selected portion of the received resistivity data; and updating the selected formation model based, at least in part, on the resistivity formation parameters.
