https://community.esri.com/t5/arcgis-image-server-questions/ndvi-landsat/m-p/670811#M1356 <P>I have these several NDVI raster scenes from Landsat (on demand) that cover my study area (15 scenes to cover all area).&nbsp;I have scenes from different dates for the different area ( due to Landsat path and data acquisition cycle). The NDVI values differ in their values (intensity) across different scenes due to changes in the ground conditions through time. Is there&nbsp;a way to normalise the NDVI values across all scenes (mosaic) so that I can compare it uniformly for my census period that occurs at a particular time period.</P> <P>&nbsp;</P> <P>Thanks for your help.&nbsp;</P> <DIV>&nbsp;</DIV> <DIV>&nbsp;</DIV> Sun, 14 Aug 2022 17:44:57 GMT VijayanSundararaj 2022-08-14T17:44:57Z https://community.esri.com/t5/arcgis-image-server-questions/ndvi-landsat/m-p/670811#M1356 <P>I have these several NDVI raster scenes from Landsat (on demand) that cover my study area (15 scenes to cover all area).&nbsp;I have scenes from different dates for the different area ( due to Landsat path and data acquisition cycle).
