You are asked to develop a vector-based index model. The model computes the index value using elevation and slope:Index value = 2 * elevation + slopeThe scoring (data standardization) systems for elevation and slope are as follows:ElevationScoreSlopeScore<= 1000'3<= 10%3> 1000'1> 10%1 You already have the elevation and slope layers. Describe the procedure you will follow to complete the task.
