I'm calculating Simple Ratio (SR) from NDVI using Raster calculator in Arcgis. Here is expression I wrote in Raster calculator.
SR=(1+float[NDVI_apr.tif])/(1-float[NDVI_apr.tif])But when I evaluate this expression, the following error always appear on the screen.
GRID ERROR-Unable to open the input grid: 1+FLOATC:\document\... Error in executing grid expression.What is wrong with this expression?
