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&nbsp;georeferenciate it once it's been converted.</P></BODY></HTML> Tue, 21 Jan 2020 17:41:44 GMT José_MariaDos_Santos_Rodrigues 2020-01-21T17:41:44Z Converting a .csv matrix into polygon shapefile https://community.esri.com/t5/data-management-questions/converting-a-csv-matrix-into-polygon-shapefile/m-p/748700#M42111 <HTML><HEAD></HEAD><BODY><P>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.
