[Qgis-user] Projection change of Open Street Map in python
Dear all, I am trying to create a map in python where I have a shape file in the BTM projection system. I want to add OpenStreetMap as the base map under the shape file. Can anyone suggest me how to change the coordinate system of the map in python?

[Qgis-user] MIKE dfsu file in QGIS
Dear all, I am trying to make a mike dfsu file visible in QGIS. For that I have used MDAL DHI Drivers. Now I have this dfsu file visible in QGIS. But when I am trying to get this map using Jupyter , all the layers from QGIS get visible in the map except the dfsu file. Can anyone suggest any solution for this?

Re: [Qgis-user] Accessing iface from jupyter
Thank you for your response. I have succeeded in adding all the shapefiles and google map layer in my map. I have another type of file which is mike dfsu file.I have added the layer dictionary in the attachment. I have five dfsu files as you can see. I need to make each layer active one at a time and create a map. So there will be five maps finally. But I can't find any resource with a solution for handling such files. Can you share any way to add such a file in a map? [image: image.png] Regards, Noshin Saiyara On Fri, 8 Dec 2023 at 03:15, Thomas Gratier wrote: > Hi, > > iface is only accessible via QGIS console.

Re: [Qgis-user] Accessing iface from jupyter to create map from QGIS
Thank you Adam for your response. I have imported iface from from qgis.utils import iface. I am working in qgis environment. It is my first work with qgis and I am finding it difficult to understand. Can you please share where I am going wrong? Is there any other way to activate a layer from multiple layers and create a map? I have google street map , shape file and dfsu file in these layers which are required to be added in the map.

[Qgis-user] Accessing iface from jupyter to create map from QGIS
Dear all,
I am trying to create a map from qgis. I have added a few layers and
created a layout in qgis. All I want is to create a script to get a map
from the layer on the layout that I have created in qgis. I have attached
the code. I am thinking of activating each layer at a time so that only the
activated layer will be on the layout and a map will get generated. While
trying to activate with iface.setactivelayer I am facing an error. So no
layer is added to the layout. I have added the code and image of the
generated map.
[image: Day-1.png]
[image: image.png]
How to access the layer in qgis? how to deactivate the first layer and then
move to the next layer for the next map.
Regards,
Noshin
