What is spatial cross-correlation?

Spatial autocorrelation is defined by one size measurement (e.g. city population) and one spatial contiguity measurement (e.g., Euclidean distance), while spatial cross-correlation can be defined by two size measurements (e.g., city population and urban area) and one spatial contiguity measurement.

What is the difference between spatial autocorrelation and spatial correlation?

Spatial correlation is positive when similar values cluster together on a map. Positive autocorrelation occurs when Moren I is close to +1. The image below shows the land cover in an area and it is an example of a positive correlation since similar clusters are nearby.

What is spatial correlation coefficient?

The spatial correlation coefficient reflects the indirect correlation based on the spatial contiguity between any two geographical entities. Pearson's correlation coefficient minus the spatial cross-correlation coefficient leaves the direct correlation coefficient.

What is the significance of spatial correlation?

The presence of spatial autocorrelation is important, (a) because it is usually taken as indicating that there is something of interest in the distribution of map values that calls for further investigation in order to understand the reasons behind the observed spatial variation, and (b) because the presence of spatial ...
