Abstract : Modern remoe sensing techniques have produced such large numbers of images that conventional analytic and evaluative procedures are no longer sufficient. Existing spatial sampling techniques were investigated to see if information could be retrieved in a less costly and time-consuming manner. More specifically, the purpose of the project was to determine whether available techniques could be used for identifying and measuring geographic features as they are depicted on maps and aerial photographs. This final report includes 6 appendices: Spatial sampling, an annotated bibliography; problems in spatial sampling; error components in scientific model building; statistical properties of spatial distributions; large scale variations in spatial data; and empirical experiments in sampling of spatial phenomena.
