Abstract:

From 1997 to 2000, the Spatial Analysis and Geomatics Applications (SAGA) section of Agriculture Division at Statistics Canada produced province-wide land cover and crops area estimates for the Prince Edward Island (PEI) Department of Agriculture and Forestry. These estimates were produced through the use of high-resolution digital satellite imagery and aerial surveillance. For the year 2001, current satellite imagery data was not available. However, due to the need for validation of the Canadian 2001 Census of Agriculture data and the importance of potatoes to PEI, a proposal to produce potato area estimates using aerial surveillance only was made. In this paper we describe the steps taken--in particular, the statistical sampling and estimation techniques--that allowed the production of potato area estimates and data quality indicators by means of aerial surveillance.
