In this step we want to create a regular grid to our model. To do this we will need to define the extend of the grid and the reference location (X and Y offset). These dimensions are declared in the coordinate system a the model.
The first step is to define the coordinate system of the model. For this we need the following lines of code:
Set model coordinate system
import Libraries.MapFunctions as mf
EPSGCode = 3857 # EPSG code for "WGS 84 / Pseudo-Mercator" coordinatesystem
fmModel.CoordinateSystem = mf.CreateCoordinateSystem(EPSGCode)
In the first line we declare the MapFunctions library as the variable "mf". The next 2 lines set the coordinate system of our model to WGS 84 / Pseudo-Mercator. To create the coordinate system we use the EPSG code (3857). To view the list of coordinate systems and there EPSG code visit : EPSG codes
The next step is to generate the regular grid using the following lines :
The first four statements define the dimensions and offset of the grid. The last statement actually creates the grid and adds it to the model. The 50 and 60 in the last statement stands for the number of cells in horizontal and vertical direction.
With the provided dimensions and offset you should get a regular grid between the British and French coast looking like this :
