How to calculate spatial correlation between two Raster?
As Jetse Stoorvogel points, the “Band Collection Statistics” in the “Spatial Analyst Tools” computes summary statistics, matrix of covariance and correlation, the documantatios is available in:
How to investigate and represent this relationship in ArcGIS?
Does anyone have any ideas of how I can investigate and represent this relationship in Arcgis? Two options – If you are doing a global correlation (between all points or cells in your study area) then extract values to points and you can use the OLS tools in the Spatial Statistics toolbox. Then you can plot the residuals.
I suspect they are closely related but I would like to produce a map output to illustrate this relationship.
How is map algebra used in raster analysis?
Raster Analysis Map algebra Concept introduced and developed by by Dana Tomlin and Joseph Berry(1970’s) Cell by Cell combination of raster data layers Each number represents a value at a raster cell location Simple operations can be applied to each number Raster layers may be combined through operations Addition, subtraction and multiplication
How are raster data layers used in GIS?

How to select layer types in raster and vector?
Select the [Show Menu] icon in the top left of the
How are raster values extracted to point locations?
Raster values, such as elevation, velocity, and temperature, are extracted to point features to identify geographic data at specific point locations.
How to find raster value difference between two rasters in ArcMap?
Option A: Use Raster Calculator. In ArcMap, navigate to ArcToolbox > Spatial Analyst Tools > Map Algebra > Raster Calculator. In the Raster Calculator window, double-click one of the rasters to be analysed, click the minus sign (-), and double-click the second raster. Specify the name and location for the output raster.
How do you add a raster layer to a point layer?
Use the Add Surface Information tool to append values of a raster layer to the input point layer. In ArcMap, click the Search icon and search for Add Surface Information (3D Analyst). For Input Feature Class, select the point layer. In this example, it is Stations_SW_LA.
