Create XY plot of raster data

ShouvikJha — Tue, 11 Oct 2016 08:21:35 GMT

Dan Patterson‌. Thank you. I want to do on cell by cell basis. I have two different parameters of raster data, so one parameter i want to plot in X axis and another one Y axis to make it relation between two parameters.

How do i convert it in row and column format. can i convert it in ASCII format?

Data is tiff format same as which we got from our above scrip suggested by Xander Bakker.

before you go off into a side tangent of graphing and trying to 'correlate', 'predict' or extrapolate see...

Geographically Weighted Regression (GWR)—Help | ArcGIS for Desktop

Only if you are working with interval/ratio and there is some real predictive behaviour between the two variables. Looking for correlations, relationships between two variables via a magical statistical test is overused. But if you are looking for an association then the above and other substitutes will save a flurry of activity in the wrong direction

For nominal data... Combine—Help | ArcGIS for Desktop gives you the basis for tests of Association such as the chi-squared test. And at worst it gives you a tabular output for discussion

Make your intent clear and specific... otherwise people with keep throwing suggestions out that will meet vague goals ... not necessary specific ones.
