The paper is devoted to estimation variance problems when sampling in spatial statistics. Anisotropic fibre processes as defined in stochastic geometry are investigated using total projections. Relation to stereological methods based on sections is emphasized. Intensity estimators are studied and the technique of estimation variances evaluation is developed. Explicit results are obtained in the Boolean segment model. The theory is applied to compare several unbiased length intensity estimators of earthworm burrow systems. © 1997 John Wiley & Sons, Ltd.
