I'm doing rainfall analysis over an area, and for that I got a .csv file comprising of a matrix where the columns correspond to latitude position over the area, rows correspond to longitude position, and each cell has a rainfall volume for that position. I want to convert this .csv matrix into a polygon shapefile showing the rainfall distribution over the area for use in ArcMap. I searched around but I only found ways to convert .csv tables with fields for coordintates, but nothing for a .csv matrix. The file itself has no coordinates but I can georeferenciate it once it's been converted.
