1. A method of converting data into a subsurface model comprising:

  • obtaining a data volume associated with a subsurface volume, wherein the data volume has a plurality of traces and each of the plurality of traces includes a plurality of samples;

    forming a vector volume from the data volume, using a computer, wherein each sample within one or more of the traces in the data volume is assigned a vector representing one or more of dip, azimuth and confidence;

    using the computer, generating a labeled volume based on the vector volume by propagating labels from at least one initial trace, wherein each of the samples is associated with one of the labels, wherein the generating the labeled volume includes,selecting a first trace from the plurality of traces within the data volume,assigning first labels to samples within the selected first trace, wherein each sample is associated with one of the first labels,propagating the first labels to samples in at least one of the plurality of traces based on the assigned first labels, the vectors and a first propagation pattern to create a first labeled volume,selecting a second trace from the plurality of traces within the data volume,assigning second labels to samples within the selected second trace, wherein each sample is associated with one of the second labels,propagating the second labels to samples in at least one of the plurality of traces based on the assigned second labels, the vectors and a second propagation pattern to create a second labeled volume, andcombining the first labeled volume and the second labeled volume into the labeled volume;

    one or more of storing the labeled volume in memory accessible by a computer system and displaying the labeled volume on a display accessible by the computer system; and

    using the labeled volume to generate a subsurface model.
