Topographic Multiplier (Mt) Detection Improvements

Until now, CHECKPOLE has used a combination of the 500 m segment criteria from the AS/NZS 1170.2 commentary (though with a “rolling” 500 m segment instead of less accurate 500 m increments from the crest suggested by AS/NZS 1170.2), in addition to our own local minimum criteria to determine the base of a feature.

Figure 1: AS/NZS 1170.2 C4.4.2

However, the problem with utilising the local minimum criteria is that the base might be determined as being at the bottom of a valley with a steep slope for certain terrain, leading to overly conservative Mt values, as shown in Figure 2.

Figure 2: CHECKPOLE v5.0.7 results

The local minimum criteria was intended to avoid situations where the 500 m segment might identify the “base” as being halfway up/down a slope, which seemed counter intuitive. Regardless, we’ve adjusted the algorithm and removed the local minimum criteria and now rely solely on the 500 m segment method. This has led to an overall reduction in Mt values across all of our test sites, as shown in Figure 3.
