I am trying to calculate CVI(coastal vulnerability index)using 7 parameters. shoreline change rate,geomorphology,mean sea level rise, tidal range, wave height,coastal slope and regional elevation.when i am putting the CVI formula in raster calculator it is returning me values in highest=1#INF and Low : -1.79769e+308. before applying the formula i have reclassified my .img files also. vector files are converted and reclassified. also the output file given by raster calculator is not displaying on screen.
