I am using ArcGIS 10.1. How do I calculate an accurate area measure for a polygon, where portions of it are falling in two zones, i.e. UTM ZONE 44 & 45 (India)?

    do you want area in just those two zones? or area in each zone? – klewis Apr 07 '16 at 16:23

    Accurate is relative here. Have you looked at this yet: http://gis.stackexchange.com/questions/3761/dealing-with-data-that-spreads-across-utm-zones – John Apr 07 '16 at 16:31

  • This is a FAQ: see http://gis.stackexchange.com/search?q=polygon+area+accurate+calculate . The short answer: use an equal-area projection. – whuber Apr 07 '16 at 22:01
