Spatial Variable Dependence-- what occurs at a
|
|
|
location
in geographic space is related to:
|
|
|
|
• |
the
conditions of that variable at nearby locations, termed
|
|
|
|
Spatial Autocorrelation (intra-variable
dependence)
|
|
|
|
• |
the conditions of other variables at
that location, termed
|
|
|
|
Spatial Correlation (inter-variable
dependence)
|
|
|
Spatial Relations Dependence-- the relationships
|
|
|
among mapped variables are:
|
|
|
|
• |
relationship constant throughout space (and time), termed
|
|
|
Spatial Homogeneity
|
|
|
|
• |
vary
as a function of space (and time), termed Spatial

Heterogeneity
