The draft of the model below
TASK: I need to calculate the percentage of river channel that is covered with shadow in each timestep
RESOURCS: I have values for azimuth and elevation of the sun (hourly timestep for daylight hours within a year – over 3000 values)
INPUTS: 1. A table (.dbf) with azimuth and elevation values 2. A river chanel mask (single polygon) 3. A DSM
How to make an interaction with two lists as parameters
The elevation value and azimuth value are assingned to a certain time and date, .I don’t want to calculate hillshade for e.g elevation row 2 and azimuth row 6 –I want only elevation row 1 + azimuth row 1, elevation row 2 + azimuth row 2, elevation row 3 + azimuth row 3… etc…
How to save an output – all the means - back to the input table – I had an idea to use a calculate field tool, but I don’t know how to “import” the values to the expression field.
I've figured out the solution to my first problem. It was easier than I thought. I Do not need to iterate. The simple for of input variable as a list and specifying the table to derive the values. But there is still the other problem - how to write the output back to the input table as a next column
