Characterizing Patterns
Résumé
The characterization of pattern requires a solid foundation in spatial sampling, and the different direct and indirect means of obtaining relevant spatial data. The scale triplet of extent, spacing and support are used as a means for structuring the understanding of spatial data (and by extension, for looking at temporal patterns), and relevant sampling strategies are discussed in relation to each. Direct and indirect ways of collecting data on appropriate ecogeomorphic parameters – vegetation, water, soil and animals – are then discussed. The potential for collecting large extents of data using remote sensing is then considered. Emphasis is given throughout on the need to consider process as central to developing robust sampling methodologies.
