Abstract
Characteristics of individual land parcels were estimated for an area in Missouri using two methods: digital spatial data and an accepted system of landowner questionnaires. For the digital data, a geographically imprecise map of land ownership parcels was digitized for a 24210 ac study area. Using a GIS, this was overlaid on a classified digital satellite image in order to estimate parcel characteristics such as mean area, size distribution, and percent of a given ownership covered by forest and/or agriculture. At the same time, a currently used ground-based questionnaire survey which is used for the estimation of the same parameters as well as socioeconomic owner characteristics was conducted. Results from the two methods were comparable for estimating parcel characteristics. The digital approach is less costly and labor-intensive, but does not provide the same socioeconomic data provided by the questionnaire. North. J. Appl. For. 11(3):80-86.
