This study uses individual survey data to investigate the impact of information about hiking destinations on estimated wilderness values in a spatial context. The data is derived from a revealed preference survey of backcountry visitors who responded to questions about their recreation behavior in the San Jacinto Wilderness of southern California. Two GIS data layers are developed showing spatial representations of non-market values derived from a Kuhn- Tucker demand model, with and without destination information. Each pixel in each data layer contains an estimate of the recreation value at that location. The destination data provides more detailed information on recreation behavior that can be used to more accurately allocate the landscape values. Results show that including destination information produces significantly greater heterogeneity in parcel value estimates for large areas of the wilderness.

本研究使用个人调查数据来调查有关远足目的地的信息对空间背景下估计的荒野价值的影响。该数据来自对偏远地区游客的一项公开偏好调查，这些游客回答了有关他们在南加州圣哈辛托荒野的娱乐行为的问题。开发了两个 GIS 数据层，显示了从 Kuhn-Tucker 需求模型导出的非市场价值的空间表示，有和没有目的地信息。每个数据层中的每个像素都包含对该位置的娱乐价值的估计。目的地数据提供了更详细的休闲行为信息，可用于更准确地分配景观价值。
