https://community.esri.com/t5/arcgis-pro-questions/total-area-for-same-study-site-changes-when/m-p/1617053#M95943 <P>Hello,</P><P>After conducting and processing my LULC for a study site between 2001 to 2020 at 5-year intervals, I have noticed that when I calculate geometry for the different interval LULC, the overall total area for these is different with the later intervals of 2015 and 2020 having a much bigger total area. This is despite using the exact study site boundary polygon to clip the raster layers during the process. As a result, I am having wrong figures for my overall change in the study site as a result of this increase on the study site overall area.</P><P>&nbsp;</P><P>Is there someone who might help with this or point out where I am going wrong in the process?</P> Wed, 21 May 2025 15:38:58 GMT Lubasi 2025-05-21T15:38:58Z https://community.esri.com/t5/arcgis-pro-questions/total-area-for-same-study-site-changes-when/m-p/1617053#M95943 <P>Hello,</P><P>After conducting and processing my LULC for a study site between 2001 to 2020 at 5-year intervals, I have noticed that when I calculate geometry for the different interval LULC, the overall total area for these is different with the later intervals of 2015 and 2020 having a much bigger total area.
