Increasing the Efficiency of Detailed Soil Resource Mapping on Transitional Volcanic Landforms Using a Geomorphometric Approach

Table 5

Cost comparison between geomorphometry approach and conventional grid method. The grid method calculations are based on a survey in 2018.

	Geomorphometry mapping units	Grid method (60 m × 60 m)
Number of samples	124	811
Number of teams	3	3
Time for survey	8	54
Cost (1 USD = 14,500 IDR)	$ 256.27	$ 1,676.07
Cost/km^2	$ 85.42	$ 558.69
