Spatial correlation means that there is a correlation between the received average signal gain and the angle of arrival of a signal. Rich multipath propagation decreases the spatial correlation by spreading the signal such that multipath components are received from many different spatial directions.

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.
How do you find spatial correlation?
You can explore the spatial autocorrelation in your data by examining the different pairs of sample locations. By measuring the distance between two locations and plotting the difference squared between the values at the locations, a semivariogram cloud is created.
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 difference between spatial and temporal correlation?
Spatial refers to space. Temporal refers to time. Spatiotemporal, or spatial temporal, is used in data analysis when data is collected across both space and time. It describes a phenomenon in a certain location and time — for example, shipping movements across a geographic area over time (see above example image).
