Calculating depth array from elevation array

TimNixon1

Hello.

At some point in the past I recall being able to calculate a depth array using channel maths by subtracting the elevation array channel from the ground surface elevation. This doesn't seem to work today. Does anyone know if i imagined this or if it is possible now?

Many thanks

Tim

Hello Tim

You can do this. Here are the steps :

Copy your input array to the output array, to generate another array with the same dimensions.

Database tools>Channel Tools>Copy Channel

Then run Math Tools
