1. An apparatus, comprising:

  • a slide estimator of a surface steerable system of a drilling rig for generating information relating to slides responsive to externally monitored data;

    wherein the slide estimator can detect whether a borehole assembly (BHA) connected to the drilling rig is in a slide mode of operation or a rotary mode of operation responsive to the externally monitored data;

    wherein the slide estimator detects a slide mode responsive to detection of a flow rate of drilling mud, a stationary BHA and an on bottom condition of the BHA; and

    wherein the detection of the flow rate of drilling mud is determined by detection of a standpipe pressure exceeding a standpipe pressure circulation threshold.
