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.
