Surveying tree rows and windbreaks by line intersec sampling

Abstract

The survey of tree rows and windbreaks is of remarkable interest in the context of forest multiresources inventories. In such a perspective, this work reports the experimentation of an innovative survey procedure based on line intersect sampling designs on remotely sensed images. Under the examined conditions, designs based on a relatively high number of survey units characterized by a relatively limited length prove to be more precise and accurate than those based on a few longer survey units. Survey units configured as radial line clusters, displaced under a random design, can be generally suggested.
