hi, if I want to create subbasins in the basin, I have to create outlets manually and use subcathment?

Hello, congratulations on the course. I was learning a lot, but at this point the instructions became very complex and I don't understand how to use the commands. Is there an easier way? or is it only possible with manual insertion of commands?

[@HansvanderKwast]

There's the PCRaster documentation and courses at www.pcraster.eu. Soon there will be an open course on PCRaster released. I'll post an update on the channel when it's ready.

Hello Sir, Can't we give coordinates as direct input, why do we need to use col2map function?

[@HansvanderKwast]

The catchment operation needs as an input a PCRaster map with the outlet. There's a new video that shows how to integrate col2map in your script: kzbin.info/www/bejne/iJimh4aObM13j6M Alternatively you can create a map from coordinates by using a NumPy array and converting it to PCRaster format with numpy2pcr: pcraster.geo.uu.nl/pcraster/4.3.0/documentation/python/reference.html?highlight=numpy#pcraster.numpy_operations.numpy2pcr

Hello Sir. lot's of thanks for this wonderful vedio on PCRaster . Sir I have a problem in last step when I run cmd "aguila rurcatchment.map" . It gives "Data source rurcatchment.map:cannot be opened".Will you please help me

Assuming that you have the file, the error means that it can't find the file. Maybe you're in the wrong folder.

Thank you @Hans van der kwast Sir. Can I covert .map format file to GeoJson file?

[@HansvanderKwast]

@@omkarkadlag8916 The PCRaster format is a GDAL supported format, so you can convert to any other GDAL supported format.

Is this would work on Pycharm? or i have to download anaconda for it?

[@HansvanderKwast]

It runs on Python. The IDE can be chosen and works as long as it is configured. More info here: pcraster.geo.uu.nl/quick-start-guide/
