I will be using aerial photography/Object Based Image Analysis to separate plants in a field from their background, creating a polygon for each plant.
I will then convert these polygons to point on centroid and retain each polygon's area attribute, yielding DATASET 1.
I have a raster map of soil moisture of this field, DATASET 2, upon which I will overlay and georeference DATASET 1.
I will be normalizing the data so all raster pixel values in DATASET 2 and point values in DATASET 1 fall between 0 and 1.
I want to analyze the spatial correlation between the values of the points in DATASET 1 (plant area) collocated with values in DATASET 2 (soil moisture).
Can anyone suggest a technique to execute this? I have done a lot of research yet am finding it hard to find precedent to wrap my head around the problem.
I will be using ArcGIS 10.3 for Desktop to process the datasets.
