Hello everybody!
I have a grid file of 4x5 cells. This file contains values of water velocity.
I also have a polygon shapefile that contains the information of land use in the same region.
I am reading the velocity cell values one by one and according to these values and the type of land use, I want to solve a specific equation.
My problem is that I am reading the velocity values from the grid file and everything is ok, but how can I read simultaneously the respective types of landuse from the shapefile in the respective location of every grid cell?
I have managed to read a shapefile by the use of the following code:
But obviously these commands read the whole shapefile. I only need to read the respective values in the specific cells.
I imagine that a solution is to convert the land use shapefile to a grid file but is there any other way?
I am a new Python user and unfortunately I can’t imagine yet what Python can do…
Thank you very much for your time!!!
