SADIE as tool for heterogeneity quantification: practical cases in Sierra Nevada National Park (Granada, Spain)

Abstract

SADIE as tool for heterogeneity quantification: practical cases in Sierra Nevada National Park (Granada, Spain). SADIE is a tool for spatial analysis based in distance indices. Its simply methodology, quantifies the spatial pattern of a focal variable, reveals local clusters
of the variable and measures the association or dissociation degree between variables. SADIE creates continuous statistics in each sample point, in this way, different characteristics of the spatial pattern should be mapped. SADIE can be use with data of different nature although different  shortcomings  of  this  methodology  are  described.  The  creator  of  SADIE  have  also  designed  a  software,  which  can  be  use  in
windows, facilitating the harness of this tool. As example, different results from a field study about small-scale spatial variation of abiotic factors in Sierra Nevada National Park are presented. Lately, this spatial analysis tool has been widely used in scientific literature because its versatility and simplicity.
