Developing Standards for Trail Conditions Using Image Capture Technology

Abstract This study compares normative standards for trail impacts measured using three alternatives suggested by the literature. During September and October 2002, data were collected from a survey of 281 day hikers at three trail locations in Mudeung-Mountain Provincial Park, Korea. For the overall photo evaluation method (OPEM), respondents were asked to rate the acceptability of bare soil area for each of a series of photographs. For the specific photo evaluation method-1 (SPEM-1), respondents were asked to select a photograph that illustrated the largest acceptable proportion of bare soil area from a series of 10 photographs. For the specific photo evaluation method-2 (SPEM-2), respondents were asked to circle a number representing the largest acceptable proportion of bare soil area on a scale after looking at three referent photographs. Aggregated normative standards varied somewhat for different measurement alternatives and trail locations. Although SPEM-1 was the easiest alternative for respondent...
